Relaxed walk to Butakovka waterfall - the one in the closest proximity to the city (Butakovka gorge).
Easy relaxed hike is friendly to kids and beginners. This small (apprx 20m height) but still awesome waterfall really worth it.
The last part of the path is likely to be bit slippery so trekking poles are recommended (provided free of charge).
Fee: $50/group of 1-3 people.
