At the beginning of the Matka Canyon, there are various stalls, then a narrow path leads along the cliffs past the dam to the oldest artificial lake in the country. There, you can continue by boat or enjoy a meal and a drink at the restaurant.
When I was there on a Monday, it was relatively quiet, so it was possible to cycle into the gorge. During peak season or on weekends, this would probably be impossible.
There are ten caves in the Matka Canyon, the shortest of which is 20 meters long and the longest 176 meters. Visitors and tourists can explore the Vrelo Cave during a 20-minute boat ride in the Matka Canyon.
