From here, you can go up to the top of Mt. Kariyose for about 20 min. walk on the steep trail. Very few people may walk on this trail, so you can enjoy very quiet walking in the forest. However, in summer, grasses are grown so it will be hard to walk.
Tama area is the name of the western part of Tokyo Metropolis. It consists of 26 cities, 3 towns and a village. A lot of people (about 4 milion) live in a eastern half part of the area. However, there are many mountains in the western part of Tama area, and there are very little flat land. Many hiking spots are in the western area, so you can enjoy walking on the trail, camping, and so on. If you see the beautiful mountain scene, you may not believe this is also in Tokyo.
