Tidepool Etiquette

Some of the most beautiful and unique discoveries are found just beyond the beach. In some coastal areas, the changing tides expose pools of water trapped in rocks, along with the varied plant and animal life that inhabit them. These habitats in the intertidal zone are known as tidepools or rockpools.

The best times to explore these tiny worlds come when there is a negative low tide—one that is lower than the average low tide—and when the seas are calm enough that waves don’t ripple the surface or pose a danger to visitors.

There are some rules of etiquette that help protect and preserve these windows into the ocean. The ecosystem and the animals living in tidepools can be very delicate and vulnerable when the low water exposes them to the air. Basic guidelines are to observe without touching, leave everything where you found it, and walk carefully over all exposed surfaces. The goal is to minimize your impact on the area and protect coastal wildlife, while keeping you safe.

Animals and plants in tidepools are very resilient, adapted to changes in temperature, water levels, oxygen, and more as the tides bring water into and out of the tidepools. In addition to seaweed and algae, tidepools can be home to starfish, anemones, crabs, fish, barnacles, chitons, limpets, and a variety of mollusks. When the water level is low, it’s a great opportunity for beachcombers to study marine life up close.

1. Pick a safe time. Check local tide charts and weather to find a time when the lowest tides will occur and waves won’t be a problem. Plan on visiting between one hour before the lowest tide to one hour after the lowest tide.
2. Keep it clean. Before you visit, wash off sunscreen, hand sanitizer, and bug spray in case you touch the water in the tidepools. Pack out all your litter and any other trash you come across.
3. Don’t turn your back on the ocean. Always be aware of the ocean and look up every now and then to make sure the tide isn’t rising faster than you planned and waves are not getting closer and bigger.
4. Watch your step. Walk slowly to avoid harming plants and animals, as well as the fragile structures that form the tidepools. Wear sturdy shoes to make sure you keep your balance and don’t slip on seaweed-covered rocks. Be on the lookout for animals that might be camouflaged on the rocks. Do not wade into tidepools—stay on the bare rocks or sand.
5. Look but don’t touch. Animals, plants, rocks, and shells are all part of the tidepool ecosystem and can be very fragile. Don’t poke, pry, or handle the animals and plants to prevent injury and stress. Don’t turn over rocks or toss anything into the pools or take anything from the tidepools, including shells and rocks, which may be shelters for tidepool creatures.
6. Give the locals space. Many shorebirds, fish, crustaceans, and even sea mammals forage in tidepools for their meals. Be sure to give them space and keep sound to a minimum so you don’t disturb them.
7. Watch your beach buddies. Keep children within arm’s reach and if dogs are allowed in the tidepools, keep them leashed and under control.

By practicing good tidepool etiquette, you can not only enjoy viewing these mini habitats along the seashore, but you can help maintain a healthy marine environment for generations to come.
