Ranchi is considered to be a hill station, but it is really a fairly fast moving place. It is 650m above sea level. Nearby is the interesting Jagannath Temple in Jagannathpur.
There are nice waterfalls in the area. Hundru Falls (44km) is one of the best. Also good are Dassamghagh Falls (35km) and Johna Falls (40km). The falls are best seen right after the monsoon.
