Fujisawa has three major topographical features: the island of Enoshima to the south connected to the Katase shoreline area by a road bridge, and two rivers, the Hikiji and the Sakai, which run north-south. The Hikiji can be traced from an area designated as a nature reserve park in the city of Yamato and flows directly along the boundary of the joint US Navy and Japan Maritime Self-Defense Force Atsugi Naval Air Base and the United States Army Camp Zama. The Sakai runs directly from the mountains between Machida and Hachiōji, and for quite some distance forms the border between the Tokyo Metropolitan Area and Kanagawa Prefecture. From Machida city centre, the river can be directly followed by a foot and cycle path to Fujisawa city centre, a distance of approximately 35 kilometers. Another cycle path runs along the Shonan Coastal path, from the Sagami River, in Hiratsuka, to Enoshima Bridge in Fujisawa.
