Snorkeling Gear
for Hawaii

What to bring, what to rent, and what Hawaii law requires — complete gear guide

✅ Quick Gear Checklist
✓ Snorkel mask (own or high-quality rental)
✓ Snorkel tube (dry-top preferred)
✓ Fins (full-foot for warm water)
✓ Reef-safe sunscreen (zinc/titanium)
✓ Rash guard (sun + coral protection)
✓ Snorkel vest (especially non-swimmers)
✓ Mesh bag for gear
✓ Anti-fog solution for mask
Hawaii law: Sunscreens containing oxybenzone or octinoxate are banned from sale in Hawaii. Use mineral sunscreen (zinc oxide or titanium dioxide) to protect coral reefs.
Essential Gear — What You Need
🔄
Snorkel Mask Must Have
The mask is the most important piece of gear. A poorly fitting mask leaks constantly and ruins the experience. When choosing a mask: press it against your face without using the strap and inhale — it should hold suction for several seconds. Full-face masks look appealing but are generally not recommended for serious snorkeling; they limit field of view and can accumulate CO2 if improperly designed.
Bring from home? Yes, if you snorkel more than once per trip. Rental masks are often stretched, scratched, or poorly sealed. Your face is unique — finding a mask that fits well is worth doing at home before you travel.
🦔
Fins Must Have
Fins give you propulsion and reduce the effort needed to cover distance. Full-foot fins (like booties with blades) are ideal for Hawaii’s warm water. Open-heel fins with booties are better if you’re walking over rocky lava entries. For entry-level snorkeling, shorter, stiffer fins are easier to control. Longer fins give more power for deeper dives and rougher currents.
Bring from home? Yes if they’re not too bulky for your luggage. Rental fins are often poor quality and the wrong size. Fit matters — fins that are too loose will chafe and fall off.
🌞
Reef-Safe Sunscreen Required by Law
Hawaii law bans sunscreens containing oxybenzone and octinoxate — chemicals that cause coral bleaching and DNA damage in marine life. Use mineral-based sunscreen with zinc oxide or titanium dioxide as the active ingredient. Apply 20–30 minutes before entering the water. Brands available in Hawaii: Stream2Sea, Raw Elements, Badger, Thinksport.
Best strategy: Wear a long-sleeve rash guard to cover most of your body, then use mineral sunscreen only on exposed areas (face, back of legs, feet). This minimizes chemical input to the ocean and provides better sun protection than sunscreen alone.
📷
Underwater Camera Recommended
The Hawaiian reef is incredibly photogenic. At minimum, a waterproof phone case or a GoPro lets you capture sea turtles, reef fish, and coral. Dedicated underwater cameras like the Olympus Tough series give better color accuracy. For selfie sticks — be cautious around coral, as you can accidentally damage fragile reef if you’re not paying attention to where you’re kicking.
Safety Gear — Strongly Recommended
🛁
Snorkel Safety Vest Recommended
A snorkel vest (inflatable buoyancy vest) is one of the best safety tools for recreational snorkelers. It allows you to rest without treading water, helps in currents, and keeps your head at the surface. Orange and yellow vests are visible to boat operators. If you’re not a strong swimmer, this is non-negotiable. Tour operators at Molokini, Hanauma Bay, and Kauai’s Na Pali coast typically provide them.
👒
Rash Guard Strongly Recommended
A rash guard (UV-protective shirt) is essential in Hawaii. It protects you from the intense tropical sun, prevents coral scrapes, protects from jellyfish tentacles, and reduces how much sunscreen you need. Long sleeve, UPF 50+ rated rash guards are ideal. Women often add leggings or a full wetsuit top for full-body protection. For cooler water at Molokini or winter dives, a 2mm wetsuit provides warmth plus protection.
Hawaii UV note: The UV index in Hawaii regularly hits 10–11+ (Extreme). Even 15 minutes of unprotected sun exposure can cause sunburn. A rash guard is not optional if you’re in the water for more than a few minutes.

Guided Tour vs DIY Snorkeling

Choose a guided tour if: You’re visiting Molokini Crater or the Na Pali coast (boat access required), you’re not a confident swimmer, you want gear provided and safety staff on-site, or it’s your first time snorkeling in Hawaii. Quality operators provide good gear, a snorkel vest, and a marine naturalist guide.

DIY snorkeling works well at: Hanauma Bay, Sharks Cove, Kahaluu Beach, Poʻipū Beach, and most calm beach parks. Bring your own gear, check water conditions in advance, never snorkel alone, and always wear a vest if you have one.
