10 Essential Gear Picks for State Park Swimming Hole Exploration

Finding a hidden swimming hole deep within a state park is one of the most rewarding ways to beat the summer heat. However, transitioning from a dusty hiking trail to a slippery, rocky pool requires gear that can handle both environments without failing. Having the right equipment ensures a seamless, safe transition from trail to water, turning a potential safety hazard into an unforgettable afternoon of exploration.

How to Assess a New Swimming Hole Before Diving In

Before splashing into any natural pool, safety must be the absolute priority. Never dive headfirst into a natural pool; hidden boulders, submerged logs, and shifting sandbars can easily hide just beneath the surface. Walk into the water slowly to gauge the depth and feel for underwater hazards with your feet before attempting to swim.

Pay close attention to water movement, especially near waterfalls or narrowing creek channels. Strong undercurrents, hydraulics, and undertows can trap even strong swimmers beneath the surface. If the water looks churning, foamy, or muddy, it is best to stay on the banks and find a calmer pool downstream.

Identify your entry and exit points before committing to the water. Moss-covered rocks and muddy banks can become incredibly slick once wet, making it difficult to climb back out. Look for gentle gravel slopes or sturdy rock shelves that offer reliable footing for an easy exit.

Water Shoes – Astral Loyak Outdoor Minimalist Shoes

Slipping on wet river rocks or cutting a foot on a submerged sharp branch can ruin a backcountry trip instantly. Standard water shoes are often too flimsy for hiking, while heavy hiking boots dry slowly and weigh you down in the water. You need footwear that transitions seamlessly from dry trails to slippery, submerged boulders.

The Astral Loyak Outdoor Minimalist Shoes excel because they feature a high-performance G.15 high-friction rubber outsole that grips wet rocks like glue. The low-profile, flexible design allows your feet to bend naturally, while the durable Cordura nylon uppers resist tears from sharp river debris. Engineered drainage holes in the toe and heel ensure water sheds instantly the moment you step back onto dry land.

• Outsole: G.15 high-friction rubber, non-marking
• Upper Material: 1000D Cordura nylon with stretch mesh
• Drainage: Built-in flush holes at toe and heel
• Sizing: True to size; snug fit recommended for water use

Because these are minimalist shoes, they offer very little arch support or thick cushioning underfoot. If you are carrying a heavy multi-day backpack or require rigid orthopedic support, these may cause foot fatigue on long approach hikes. They are best for day-trippers who want a lightweight, highly tactile shoe that excels in wet, slippery conditions.

Dry Backpack – Sea to Summit Hydraulic Dry Pack

Exploring a state park often means wading through deep pools or navigating mist-heavy gorge trails to reach the best swimming spots. A standard backpack will quickly soak your dry clothes, lunch, and electronics. A dedicated, submersible-capable dry pack keeps your gear bone-dry, even if you take an accidental swim.

The Sea to Summit Hydraulic Dry Pack stands out with its heavy-duty 600D TPU-laminated fabric that resists punctures and UV damage. Unlike basic dry bags with uncomfortable straps, this pack features a removable harness system made of open mesh and foam for comfortable carrying over long trail miles. The secure roll-top closure and welded seam construction ensure water stays out, even under heavy spray or brief submersion.

• Capacity Options: 35L, 65L, 90L, and 120L
• Material: 600D TPU-laminated heavy-duty waterproof fabric
• Harness: Removable, adjustable shoulder straps and waist belt
• Closure: Roll-top with interlocking buckles

When packing, always roll the top at least three times to guarantee a waterproof seal. While the harness makes hiking comfortable, this bag is relatively bulky and stiff compared to a standard daypack. This pack is perfect for those carrying expensive camera gear or electronics through wet canyons, but it is overkill for a simple, dry-trail walk to a paved beach.

Pack Towel – PackTowl Personal Microfiber Towel

Carrying a standard cotton bath towel on a hike is a recipe for a heavy, soggy, and musty backpack. Traditional towels take hours to dry, collecting dirt and leaves every time they touch the ground. A specialized, compact travel towel dries quickly and packs down to the size of a fist.

The PackTowl Personal Microfiber Towel is the ideal choice because it can absorb four times its weight in water and wring out almost completely dry. It features a soft, polyester-nylon blend that feels comfortable against the skin, unlike scratchier utility microfibers. An integrated Polygiene odor control treatment prevents that familiar damp-towel smell, even when packed away damp for the hike home.

• Sizes: Face, Hand, Body, and Family (up to 36 x 59 inches)
• Material: 85% Polyester, 15% Nylon microfiber
• Dry Time: Dries up to 70% faster than cotton towels
• Attachment: Hanging loop with snap button included

Microfiber towels require specific care; washing them with fabric softener will clog the fibers and ruin their absorption capabilities. They also tend to cling to dry leaves and pine needles if laid directly on the forest floor. This towel is perfect for backpackers looking to save weight, but beachgoers who prefer thick, plush terrycloth may find the thin texture takes some getting used to.

Snorkel Set – Cressi Palau Mask Fin Snorkel Set

State park swimming holes often hold hidden underwater worlds, from ancient rock formations to freshwater fish hiding in deep pools. Standard goggles fog up quickly and do not allow for easy breathing while looking down. A quality snorkel set opens up a whole new dimension of exploration by keeping your vision clear and breathing relaxed.

The Cressi Palau Mask Fin Snorkel Set features short, adjustable-strap fins that are easy to walk in along rocky bank edges. The mask is constructed with hypoallergenic liquid silicone that molds comfortably to various face shapes to prevent water leaks. The snorkel utilizes a semi-dry top design to reduce water entry from splashing waves, while a purge valve makes clearing water effortless.

• Fins: Short blade, open-heel design with adjustable straps
• Mask Lens: Tempered glass for clear vision and safety
• Snorkel: Semi-dry top with lower purge valve
• Included: Mesh carrying bag for quick drying

Keep in mind that open-heel fins require a snug fit, and wearing them over thin neoprene socks can prevent blisters on sensitive skin. Because these are short snorkeling fins, they do not provide the massive propulsion needed for strong ocean currents or deep scuba diving. They are specifically optimized for recreational swimmers exploring calm, sheltered freshwater pools and slow creeks.

Waterproof Case – JOTO Universal Waterproof Pouch

You want to document your swimming hole adventures, but dropping your phone onto a wet rock or into a deep pool can be a costly mistake. Stashing your phone deep inside a dry bag prevents you from taking quick photos. A wearable, waterproof phone pouch keeps your device secure, accessible, and dry right around your neck.

The JOTO Universal Waterproof Pouch features an IPX8 certification, meaning it can handle complete submersion up to 100 feet. The clear, highly touch-sensitive windows on both sides allow you to operate your touchscreen and take clear photos underwater without removing the phone. It utilizes a simple, secure snap-and-lock seal that keeps out water, fine sand, and mud.

• Compatibility: Fits smartphones up to 7.0 inches diagonally
• Waterproof Rating: IPX8 certified (submersible to 100 feet)
• Carrying Option: Durable, adjustable neck lanyard included
• Design: Double-sided clear windows for camera use

Be aware that touchscreen functionality can be temperamental under water pressure; using your phone’s physical volume buttons to snap photos works much better when submerged. Always perform a quick paper towel test at home before trusting it with your expensive phone. This pouch is an absolute necessity for casual explorers, but those seeking professional-grade underwater videography will eventually want a dedicated hard-shell camera housing.

Backpack Cooler – RTIC Everyday Cooler Backpack

Nothing spoils a great day at a swimming hole faster than warm drinks and soggy, sweat-ruined sandwiches. Carrying a heavy, rigid plastic cooler over a mile of rough state park trails is exhausting and impractical. A backpack cooler distributes the weight across your shoulders, keeping your hands free for balance on tricky terrain.

The RTIC Everyday Cooler Backpack is engineered with heavy-duty closed-cell foam insulation that keeps ice frozen for up to 24 hours. The exterior is made from a durable, water-resistant fabric that resists scuffs from branches and rocks, while the leakproof zipper prevents cold water from dripping down your back. It features comfortable, padded shoulder straps and external pockets to hold dry goods, keys, and utensils.

• Capacity: Holds up to 15 cans with plenty of ice
• Insulation: High-density closed-cell foam
• Exterior: Heavy-duty, puncture-resistant polyester
• Comfort: Padded shoulder straps with chest strap

To maximize ice retention, pre-chill the cooler with cold water or a sacrificial bag of ice before packing your actual supplies. Because this cooler relies on thick insulation, the interior volume is slightly smaller than the exterior dimensions suggest. This backpack is perfect for couples or small families heading out for a day hike, but it won’t hold enough food for a multi-day group camping trip.

Insulated Bottle – Hydro Flask 32 oz Wide Mouth

Staying hydrated is critical when hiking in the hot sun, but drinking lukewarm water from a plastic bottle is miserable. Single-use plastic bottles also sweat constantly, wetting everything in your pack, and they pose an environmental hazard if dropped. A high-quality insulated bottle keeps your water ice-cold from the morning drive to the late-afternoon hike back.

The Hydro Flask 32 oz Wide Mouth bottle uses TempShield double-wall vacuum insulation to keep beverages cold for up to 24 hours. Made from durable 18/8 pro-grade stainless steel, it won’t transfer flavors or sweat on the outside, keeping your hands and gear dry. The wide mouth opening makes it easy to drop in ice cubes and facilitates quick cleaning after a dusty day on the trail.

• Volume: 32 fluid ounces (946 ml)
• Material: 18/8 Pro-Grade Stainless Steel, BPA-free
• Cap Compatibility: Wide Mouth Straw Lid, Flex Cap, or Chug Lid
• Finish: Color Last powder coat for slip-free grip

Stainless steel bottles are heavier than lightweight plastic or collapsible bottles, adding a bit of weight to your load. They can also dent if dropped directly onto hard river boulders, although this does not usually affect the vacuum insulation. This bottle is an indispensable companion for anyone who demands ice-cold water on hot summer days, but ultralight hikers may prefer lighter, non-insulated options.

First Aid Kit – Adventure Medical Kits Ultralight .7

Wet, mossy rocks and hidden underwater branches are prime spots for minor slips, scrapes, and cuts. Being miles away from your vehicle with an open wound is a major infection risk, especially in natural water sources where bacteria thrive. A compact, waterproof first aid kit ensures you can quickly clean and dress wounds on-site.

The Adventure Medical Kits Ultralight .7 is specifically designed for multi-sport enthusiasts who need to keep weight down without sacrificing medical capabilities. The inner contents are protected by a two-stage waterproofing system, including a rugged outer nylon bag and an inner DryFlex waterproof bag. It contains professional-grade bandages, antiseptic wipes, blister treatments, and basic medications tailored for one to two people on day trips.

• Weight: Ultra-lightweight at just 8 ounces
• Waterproofing: DryFlex inner bag is 100% waterproof
• Group Size: Ideal for 1-2 people on 1-4 day trips
• Contents: Moleskin blister relief, bandages, medications, antiseptic wipes

While this kit is excellent for minor trail and water injuries, it does not contain heavy trauma supplies like tourniquets or splints. Users should familiarize themselves with the contents and basic first aid procedures before heading out, as a kit is only as useful as your knowledge of how to use it. It is perfect for day hikers and swimming hole explorers, but larger groups should look at the heavier .9 or 2.0 models.

Floating Keyring – Chums Floating Neo Keychain

Your car keys are your lifeline back to civilization, but they are also incredibly easy to lose in deep, murky water. A single slip near a deep pool can send your heavy electronic key fob straight to the muddy bottom, leaving you stranded. A floating keyring acts as a cheap insurance policy to keep your keys visible and on the surface.

The Chums Floating Neo Keychain features a high-visibility, foam-filled neoprene wrist lanyard that is easy to spot in churning water. It is rated to float up to 1.4 ounces, which is enough buoyancy to support a standard car key fob and a couple of brass keys. The bright, high-contrast colors ensure you can locate it instantly if it slips out of your hand or pocket.

• Buoyancy Capacity: Floats up to 1.4 oz (40g)
• Material: Closed-cell foam wrapped in soft neoprene
• Attachment: Heavy-duty split ring
• Colors: High-visibility yellow, orange, and neon patterns

Always test the buoyancy of your specific key set in a sink or shallow water before trusting it in a deep swimming hole, as heavy keychains with multiple tools can overcome the float’s capacity. If you have a bulky set of keys, you may need to strip away non-essential keys or attach a second float. This simple tool is an absolute must-have for anyone heading near deep water, but it is not intended to support heavy items like waterproof cameras or multi-tools.

Mineral Sunscreen – Thinksport SPF 50+ Sunscreen

Spending hours swimming and lounging on sunny riverbanks exposes you to intense UV rays, making sun protection a priority. However, traditional chemical sunscreens wash off into the water, releasing harmful ingredients that can damage delicate aquatic life and disrupt fragile freshwater ecosystems. Using a reef-safe, biodegradable mineral sunscreen protects your skin without harming the environments you came to enjoy.

The Thinksport SPF 50+ Sunscreen is a highly rated mineral formula that relies on 20% non-nano zinc oxide to physically block harmful UVA and UVB rays. It features a water-resistance rating of 80 minutes, meaning it stays on your skin during prolonged swims rather than washing off immediately into the water. The formula is free of biologically harmful chemicals like oxybenzone, avobenzone, and parabens, and it goes on smoothly without leaving an excessively greasy residue.

• Active Ingredient: 20% Non-Nano Zinc Oxide
• Sun Protection: Broad Spectrum SPF 50+
• Water Resistance: Up to 80 minutes
• Formulation: Non-toxic, biodegradable, gluten-free, and vegan

Because mineral sunscreens create a physical barrier on the skin, they require a bit more effort to rub in completely and can leave a slight white cast. Be sure to apply it at least 15 minutes before jumping into the water to allow the lotion to set properly on your skin. This sunscreen is perfect for environmentally conscious swimmers, but those who dislike any visible residue may need to rub it in more thoroughly.

Cleaning and Drying Your Swim Gear to Prevent Mold

Returning home after a successful day at a swimming hole is only half the journey; caring for your gear afterward ensures it lasts for seasons to come. Leaving wet shoes, towels, and dry bags packed away in a hot car trunk is a guaranteed way to breed mold, mildew, and foul odors. Always unpack your gear immediately upon returning home and rinse everything thoroughly with clean, fresh tap water to remove sand, silt, and algae.

Hang your gear to dry in a well-ventilated, shaded area out of direct sunlight, as prolonged UV exposure can degrade waterproof coatings and break down synthetic materials. Open all zippers on dry packs and cooler bags, and hang them upside down so water can drain out completely. Ensure water shoes are fully dry before storing them in closed closets to prevent bacterial growth and persistent odors.

Proper cleaning also plays a critical role in conservation by preventing the spread of destructive invasive species between different waterways. Always inspect your gear, especially the soles of your water shoes and the exterior of your dry pack, for any mud, plants, or small organisms. Clean, drain, and dry everything completely before moving on to your next state park adventure.

Exploring state park swimming holes is a fantastic way to connect with nature, provided you are prepared for the unique challenges of natural water environments. Equipping yourself with reliable water shoes, high-quality dry storage, and proper safety gear transforms a rugged trail hike into a stress-free aquatic adventure. Invest in gear that protects both you and the environment, and enjoy your next escape into the wild with complete confidence.
