Ruhengeri is a city in northern Rwanda's Musanze district. It is the port of call for tourists heading up the hills to Kinigi and Parc National des Volcans.
There several bus companies who serve Kigali-Musanze direction every half hour for 1,700-1,800 rwf (July 2012). The journey takes 2 hours.
Buy your ticket at the main bus station in Nyabugogo - each bus company has their own little office, look for the signs that say "Kigali-Musanze." Don't buy your ticket in advance - go to the bus station and expect to leave in roughly 30 minutes. If you book your ticket right before you leave, you may get a bad seat or have to stand.
Musanze is a small town, you can walk from one end to the other along the main road in 30-40 minutes.
The best way to get around is walking or moto-taxi. Prices are negotiable with the moto drivers, but a typical ride across town is 300-400 rwf (July 2012.)
Volcanoes National Park offers several attractions. Tickets must be booked in advance through tour companies or the Rwanda Tourism Board (ORTPN).
The majority of revenue from tourism goes towards maintaining the park and conserving the wildlife. The remainder goes to the government and (around 10%) to local projects in the area to help local people benefit from the large revenue stream generated by the park.
