Beautiful place and worth checking it out! There are many activities here, via ferrata (rock climbing and hiking), rafting, boating, hiking etc. No entrance fee, there is free parking and a small bar where you can grab drinks near the river. Open at all times! Just make sure it doesn’t get too dark because this is a forest.
