How to get to Aharen Beach snorkeling spot?

Aharen Beach is located on Tokashiki 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 Tokashiki, 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 35-minute ride to reach the island) but you might prefer the cheaper ferry (70 minutes).

The easiest way to reach Aharen Beach from Tokashiki island jetty is the bus shuttle waiting for passengers each time a boat arrives (about 20 minutes). You can also rent a vehicle or grab one of the island’s rare taxis. Aharen is a tiny village, you will have no trouble finding its adjacent beach.

Aharen beach reefs are overall well preserved, although some areas can be damaged. In the best-preserved areas, vibrant, bright-colored gardens await snorkelers. These area support rich underwater life, including blue damselfish, pairs of butterflyfish, Moorish idols, and giant clams.

Several clownfish species can be spotted in the area, but you are most likely to see the tomato clownfish, which is found even in very shallow areas (less than 3ft/1m deep). However, if you love those cute creatures, don’t miss a visit to Furuzamami Beach where they literally abound.
