Also called Yong Gasem Bay, Monkey Beach is a small piece of seashore located on Ko Phi Phi Don Island, north-west of Loh Dalam Bay. Each day, hundreds of visitors come ashore from boats looking for an encounter with the colony of crab-eating macaques living on the beach and in the neighboring jungle. But Monkey Beach is not all about monkeys; it is also a place for snorkeling lovers. Underwater life includes giant clam, schools of parrot fish, yellow damselfish standing above coral clumps and clownfish in their anemones.
Monkey Beach is facing north. It is located a few hundred meters north-west of Loh Dalam Bay. To get there, you can choose from several options.
First you can take part of a boat tour (speedboat or long tail boat, half day or full day trip). Quite a lot of companies run daily tours not only from Ko Phi Phi center, but also from Phuket and Krabi. They include stops at other neighboring snorkeling spots such as Maya Bay and Bamboo Island.
If you prefer a more active mode of transportation, you can also rent a kayak in Loh Dalam Bay. Paddling to Monkey Beach requires half an hour: consider renting your kayak for at least two hours.
Finally, you can take advantage of low tide and simply walk to the beach (you will have to walk along the shoreline for about 500 meters). We don’t recommend this risky option: rocks are slippery and you have to take tide times into account.
Enter the water from the sandy beach. Avoid the area where the numerous boats moor.
Monkey Beach is fringed by a coral reef about 50 meters wide. We recommend exploring the eastern part (on your right when facing the sea): coral is far denser there than it is on the western side. Tour companies know it: boats stop on this same side. Don’t hesitate to swim away from the beach towards the rocky shore; the best preserved areas are there.
The reef actually is a reef flat deepening steadily (↕1-3m) as you swim away from the shore. It ends up with a drop-off leading to deeper areas (↕3-6m). This spot is busy with swimmers and snorkelers, most of them taking part of a boat tour, so corals have been much damaged. However you will still spot a wide variety of species here.
Colorful giant clams (some of them a bright fluorescent blue) set the rhythm to a rather monotonous seabed. Bright yellow damselfish swim over tabular corals, their color flashing against the deep blue. But the true star of Monkey Beach is clownfish. This cute fish inhabits the huge sea anemones scattered on the seabed (↕2-3m). Most of them are pink skunk clownfish, with their distinctive single thin vertical white line.
The main danger while in the water comes from boats untiringly coming and going about. Stay away from the areas where they are and don’t swim further than the reef flat. On the beach, monkeys are used to be fed: they can be quite insistent and bites aren’t unheard of.
Monkey Beach is a natural site. You won’t find any snack or restaurant, but “street” vendors sometimes can be here. In doubt, bring your own water and snacks.
Snorkeling spots are part of a wild environment and their aspect can be significantly altered by weather, seasons, sea conditions, human impact and climate events (storms, hurricanes, seawater-warming episodes…). The consequences can be an alteration of the seabed (coral bleaching, coral destruction, and invasive seagrass), a poor underwater visibility, or a decrease of the sea life present in the area. Snorkeling Report makes every effort to ensure that all the information displayed on this website is accurate and up-to-date, but no guarantee is given that the underwater visibility and seabed aspect will be exactly as described on this page the day you will snorkel the spot. If you recently snorkeled this area and noticed some changes compared to the information contained on this page, please contact us.
The data contained in this website is for general information purposes only, and is not legal advice. It is intended to provide snorkelers with the information that will enable them to engage in safe and enjoyable snorkeling, and it is not meant as a substitute for swim level, physical condition, experience, or local knowledge. Remember that all marine activities, including snorkeling, are potentially dangerous, and that you enter the water at your own risk. You must take an individual weather, sea conditions and hazards assessment before entering the water. If snorkeling conditions are degraded, postpone your snorkeling or select an alternate site. Know and obey local laws and regulations, including regulated areas, protected species, wildlife interaction and dive flag laws.
These snorkeling spots are accessible to beginners and kids. You will enter the water gradually from a beach, or in a less than 3ft. deep area. The sea is generally calm, shallow, with almost no waves or currents. These spots are usually located in marked and/or monitored swimming areas. It is not necessary to swim long distances to discover the sea life.
This level only apply when the spot experiences optimal sea and/or weather conditions. It is not applicable if the sea and/or weather conditions deteriorate, in particular in the presence of rough sea, rain, strong wind, unusual current, large tides, waves and/or swell. You can find more details about the definition of our snorkeling levels on our snorkeling safety page.
