The minimum time you should consider is 2 hours, but now you can easily spend 3 to 4 hours, or if it fits you, the whole day. There is no minimum age; however, you must watch your children. We always will have tour guides watching, advising, and helping. The total walking distance is around 4.5 km, easy to moderate walk. There are six blue waterfalls to visit and many pools. You can freely choose how many of them you want to explore. It is all up to you. Also, we now offer very nice viewpoints and picnic areas. No reservations are needed.
