Muckacheve has a new aquapark with attractions, thermal pools, SPA. Which opened in July 2021. It's not big, but with normal prices and good food.
Good place for a rest on the road to Bukovel — hotel ClubHouse — not expensive, quiet and with good breakfast.
The Space Museum is a cheap way to spend a nice and interesting 1-2-3 hours, the cost is about 3 usd excursion. Highly recomend to visit.
