There’s almost nothing I love to do more than strap on a snorkel, mask, and fins and jump into an amazing, underwater world. Snorkeling is a magic window onto one of the planet’s most spectacular—and endangered—ecosystems. Coral reef scenery is mind-boggling: the life forms are otherworldly, the colors surreal.
But there’s a tragic side. Over the years, I’ve seen more and more bleached, broken coral and reefs devoid of fish. Pollution, climate change, unsustainable fishing practices, and careless snorkelers are taking a toll on fragile tropical reefs, which are disappearing at an alarming rate.
According to the World Wildlife Federation, we’ve already lost 27 percent of the world’s coral reefs. If present rates of destruction are allowed to continue, 60 percent of coral reefs will be destroyed over the next 30 years.
As an underwater enthusiast, I strive to be a good ocean steward; as a writer, I hope to raise the alarm for coral reefs. My husband and I follow ocean-friendly snorkeling practices, and I’m sharing a few tips (from Reef Relief, the Coral Reef Alliance, the National Oceanic and Atmospheric Administration) that might help us preserve fragile saltwater habitats.
1. Don’t wear sunscreen in the ocean: An estimated 4,000 to 6,000 metric tons of sunscreen washes off swimmers’ bodies and endangers coral health. A sunscreen chemical called benzophenone-2 (BP-2) is highly toxic to coral, especially juvenile coral. (By the way, coral is a living organism, not rock or shell.) To protect your skin from UV rays and sunburn, wear a wetsuit or long-sleeved shirt into the water.
2. Never touch coral. Even slight contact can harm the sensitive coral polyps. Besides, some corals can sting or cut you. Also, avoid using gloves. They may protect your hands, but some people interpret that as an invitation to handle marine life.
3. Don’t tread on coral. Select points of entry and exit from the water that don’t cross corals. While you’re snorkeling, maintain a comfortable distance from the reef (two feet or more, depending on how good a swimmer you are and how rough the water is) to ensure that you can avoid contact even in turbulent water or if you’re surprised. Know where your fins are at all times so you don’t kick coral.
4. Learn to move about gracefully in the water. You should be comfortable enough in open water that you don’t depend on big kicks or flailing arm movements. Snorkelers should wear float-coats to allow gear adjustments without standing on the coral. Practice a dolphin-like swim so that you can negotiate tight spaces without disrupting your environment.
5. Take nothing, living or dead, out of the water. The exception: you may pick up “new” garbage. If the garbage is “old” (ie: covered with sand or algae), it might now be used as a home or hiding place for crabs, small fish, or eels.
6. Don’t feed the fish. Doing so destroys their natural feeding habits, and you might be injured.
7. Avoid harassing the wildlife. Chasing, touching or picking up fish, invertebrates, and marine mammals and reptiles could hurt or kill them; at the least it makes them wary of humans and could ruin future snorkeling experiences. In Hawaiian waters, it’s illegal to touch turtles.
8. Pack out your trash. It’s illegal to dump trash at sea. Plastic bags and other debris can injure or kill marine animals.
9. Don’t buy shell or coral products from gift shops. In many places in the United States, it’s illegal to harvest coral, and purchasing it at local shops only depletes reefs elsewhere.
10. Choose an eco-friendly hotel or resort. Graywater and fertilizer/pesticide runoff pollute water around many hotels. Check with nonprofits or ecotourism sites about the hotel’s environmental policies before you book.
For instance, the Napili Kai (where I stayed) is one of a number of hotels on Maui that participates in the Coral Reef Alliance’s Hawaii Hotel Reef Stewardship Project. Participating hotels use:
- Reef etiquette signage
- In-room educational materials
- Educational tools for staff to share with guests
- Staff training in reef ecology and outreach strategies
- Supporting hotels’ watersports companies in the implementation of the Voluntary Standards for Marine Tourism

Hi! I’m so glad to have found your web page on snorkeling. You write so well and the informations provided are great (we will be more careful when choosing a car leasing company). We are preparing a trip to Hawaii next June and are planning going snorkeling as much as possible! We are presently looking to buy wetsuits and would like your advise as how thick we should consider (very thin 1 mm versus 2-3 mm…). We will be buying full length suits to avoid sun lotion . Also, do you have an opinion on full masks? We are considering changing our regular masks for one of them.
Thanks again for sharing your experiences, it does help us plan better and be better travelers! Merci beaucoup!
Enjoy your trip! I don’t know much about wetsuits: Ours are thin and keep the sun off, but if you get cold easily, you might want to go with something more insulated. On Pacific Islands, the water can be much chillier than the Caribbean, for instance.
