Take a cruise on the Urauchi River (浦内川), the longest river in Okinawa. This river runs deep inland through dense mangroves on the west side of the island and is sometimes likened to a little Amazon. The views can be quite spectacular, especially on a still morning. On your way back, pop into the little museum on the second floor of the cruise pier building, featuring a selection of stuffed and mounted big bugs and crabs including the scary-looking yashigani.

星砂の浜, Hoshizuna-no-hama
One of two beaches in Japan — the other is on Taketomi — where, for some reason, deposits of tiny white star-shaped shells regularly wash up. These days most of it ends up in bottles in souvenir shops. This area is also well suited for snorkeling. At low tide the corals form ponds that can be quite deep and semi secluded from others, so you may have to walk to get to the next pond. Coral life is limited but still worth taking a dive. The views from the terrace of the visitor center and restaurant just above the beach are beyond beautiful. If you can stand the heat and sun, make sure to sit here for a drink or some food.
ピナイサーラの滝
Pinaisala Falls is the largest waterfall in Okinawa prefecture, with a height of about 55 m. Pinai means a beard and sala means a waterfall, based on the dialect in Yaeyama islands. You can see this fall like a beard man from a long distance. There are several ways to get close to the waterfall.
イダの浜
A remote pristine beach, can only be reached by ferries from Shirahama port at the west end of the island's road. For lunch, there is a nice small restaurant at the north side of the Funauki village. Just walk straight from the port, stay close to the water and don't turn left onto the path to the Ida beach.
