A little bit away from the rest of the tourist destinations in Kyoto, Hozugawa flows through a mostly-undeveloped ravine. At the point where it exits the ravine to the relatively flat land around Kyoto, it widens and a small park exists at that transition.
Tourists planning to take the boat tour should take the JR Sagano Line to Kameoka. Alternately, take the JR Sagano Line to Saga Arashiyama, transfer to the Sagano Scenic Railway (the station is next door, called Torokko Saga) getting off at Torokko Kameoka and taking a short bus ride to the cruise terminal.
The park is free but cruises are about 4100 yen; they depart 9:00-15:30 hourly (10:00-4:30 December through early March, every 90 minutes). On busy days there are more boats and departures are irregular but more frequent. Reservations aren't possible.
