Ama Beach is one of the most beautiful beaches in the Kerama Islands. This location is especially famous for sea turtle spotting: every day, at high tide, they come here in numbers to feed on the shallow seagrass meadow. If you are spending a whole day on the island, you can combine this snorkeling with Furuzamami Beach, another good location located less than 2 miles from Ama Beach.

How to get to Ama Beach snorkeling spot?

Ama Beach is located on Zamami Island, one of the most visited islands in the Kerama archipelago. Most tours to the islands depart from Naha, Okinawa’s capital city, which is the archipelago’s gateway.

Boats to the Kerama Islands, including tours to Zamami, leave from Tomari harbor, next to the city center. The closest monorail stop is Miebashi (美栄橋), a 10 minutes walk to the jetty. The express boat is the most convenient (a 50-minute ride to reach the island) but you might prefer the cheaper ferry (120 minutes).

Once on Zamami island, there are several options to reach the beach: you can rent a bike (a 20-minute ride to the beach, following a steep road), a scooter, or a car. Ama Beach is well-signposted from the jetty.

Ama Beach snorkeling tips and recommendations

If you want to spot green sea turtles in Ama Bay, you have to snorkel the spot at high tide, when there is enough water on the seagrass beds on which the turtles feed. You will easily get information about the tides at the tourist information center located close to the jetty.

The turtle grass starts only a few meters from the beach. Exploring the area at high tide, you will most likely spot several green sea turtles feeding quietly on the grass. As always with sea turtles, respect the basic observation rules: don’t touch them or follow them, and give them enough space when they come up to the surface to breathe.

Green sea turtles are not the only attraction here. You will also find a gorgeous coral garden, densely covered with branching corals, only a few dozen meters from the beach. It is located just in front of the beach’s main access (see map above). If you have trouble finding it, look for the glass bottom boats, as they use to stop in this area.

Sea turtle watching in Ama Beach


Sea turtles are a very familiar sight at high tide at Ama Beach. In order to be a responsible snorkeler, be sure to respect the following rules when observing them:

  1. Do not attempt to touch or ride sea turtles
  2. Stay at a distance (6 to 10ft) from sea turtles
  3. Do not chase a turtle swimming away
  4. Avoid sudden movement and allow sea turtles plenty of space when they come up to the surface to breathe

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.
