The Sagami Bay shore in this area has some of the closest beaches to Tokyo, and in the hot, humid summer months it seems as though all of the city's teeming millions pour onto these beaches in search of a vacant patch of rather dirty gray sand. Pass up this mob scene and press on instead to Enoshima. The island is only 4 km (2½ miles) around, with a hill in the middle. Partway up the hill is a shrine where the local fisherfolk used to pray for a bountiful catch—before it became a tourist attraction. Once upon a time it was quite a hike up to the shrine; now there's a series of escalators, flanked by the inevitable stalls selling souvenirs and snacks. The island has several cafés and restaurants, and on clear days some of them have spectacular views of Mt. Fuji and the Izu Peninsula. To reach the causeway from Enoshima Station to the island, walk south from the station for about 3 km (2 miles), keeping the Katase-gawa (Katase River) on your right. To return to Tokyo from Enoshima, take a train to Shinjuku on the Odakyu line. From the island walk back across the causeway and take the second bridge over the Katase-gawa. Within five minutes you'll come to Katase-Enoshima Station. Or you can retrace your steps to Kamakura and take the JR Yokosuka line to Tokyo Station.
