The Basic Snorkel Set
Hawai’i Ocean Safety describes traditional snorkeling equipment as a snorkel tube, face mask and fins. Familiarity with that equipment before you enter the ocean is part of safe preparation.
Mask
- Seals around your face
- Comfortable nose pocket
- Clear field of view
- Strap adjusted before entry
Snorkel
- Tube is clear of obstructions
- Mouthpiece feels comfortable
- You know how to clear water
- Practice breathing first
Fins
- Fit snugly without pinching
- Easy for you to control
- No loose straps
- Shorter movements near reef
Mask Fit
A leaking mask quickly turns a calm snorkel into a frustrating one. Before entering the ocean, position the mask evenly, keep hair out of the seal, adjust the strap without overtightening, and confirm you can remove it easily.
Fins Near Shallow Reef

Control is more important than power
Hanauma Bay’s reef flat is shallow. Strong downward kicks can strike coral, stir sediment or push you into reef. Use small relaxed kicks and stay over water deep enough for your fins to clear the bottom.
Never stand on coral to adjust gear or rest. Return to sand or shore.
Flotation Aids
Hawai’i Ocean Safety suggests considering a flotation device appropriate for snorkeling, such as a snorkel vest or belt. A flotation aid can reduce effort, but it does not replace swimming ability, a buddy, good conditions or lifeguard advice.
Full-Face Masks
Hawai’i Ocean Safety notes ongoing safety questions about full-face snorkel masks, including possible carbon dioxide buildup, difficulty removing the mask, leaking and ball-valve problems. Research is still developing, so the state does not describe all full-face masks as inherently unsafe.
If you use one, make sure it fits correctly, practice breathing and removing it before entering the water, and stop immediately if you feel dizzy, disoriented, short of breath or develop a headache.
Bring or Rent?

Bring your own if fit matters
The current DLNR Hanauma Bay facilities list includes restrooms, showers, phones and a snack bar, but does not list snorkel rentals. Concession services have changed over time.
For that reason, do not arrive depending on on-site rental availability unless you have confirmed it for your date. Some permitted tours include gear.

FAQs
Can I rent snorkel gear at Hanauma Bay?
Do not assume on-site rental is available. Current DLNR facility information does not list snorkel rental, and concession operations have changed over time. Bring your own gear or confirm current rental/tour arrangements before your visit.
What gear do I actually need?
A traditional setup is a mask, snorkel and fins. A snorkeling-specific flotation vest or belt is optional and may help some swimmers conserve energy.
Are full-face snorkel masks safe?
Hawai’i Ocean Safety says questions remain about full-face mask safety and more research is needed. Proper fit, easy removal, calm breathing and immediate exit if you feel unwell are important.
Should beginners use fins?
Fins can make movement easier, but beginners should practice with them first and use controlled kicks, especially around shallow reef.
Can flotation gear make a non-swimmer safe?
No. Ocean Safety says snorkelers should be experienced ocean swimmers. Flotation equipment does not replace swimming ability or safe conditions.
