Chichibu-Tama-Kai National Park

Flora and fauna
The most popular access route is on the Seibu Chichibu Line (西武秩父線) from Ikebukuro in Tokyo to the terminus Chichibu station (75 minutes, ¥1370 via limited express).
For access to the Oku-Tama region, take the JR Chuo line to terminus Ome (75 minutes), transferring at Tachikawa if necessary. From here, transfer to the Ome line; a trip to (eg.) Mitake station from here takes 20 minutes and costs ¥890.
As the region is best known for its hiking, the recommended way of getting around is on foot.
It is possible to hike Mitsumine and Mitake either separately as day trips, or as a full day's hike along the trail connecting the two.
There are a number of basic food stalls and tea houses on the short trail connecting Mitsumine-guchi to the cable car station.
Be aware that landslides occur in this region. Check the weather report for heavy rains. When walking in the mountains make sure someone knows where you are starting from, where you are going and what trail you intend to use. There are paper slips at most trails that should be filled out with name, address, route and contact information for nearest relative. An exit slip is filled in at the end of the trail.
