I would definitely recommend this tour to anyone interested in a shorter nature hike. Gorgeous views, really fun but mild bouldering and refreshing swims in natural pools & rivers. Our guide Tu did an excellent job! Great english, knowledgable, social and well prepared. Also, my wife is a vegetarian and we forgot to mention that before the tour began. For the provided lunch, Tu re-directed us to the most amazing local Vietnamese Vegetarian restaurant and it was the perfect ending to a great day. Several other pieces of advice. (1) Bring some water as well. Yes the tour provides some but generally tourists need a lot more water than locals around here! (2) Remember your sunscreen. (3) Remember a towel with your change of clothes. There are showers available at the park entrance so you can rinse off before putting on your fresh clothes, but a towel would have been nice. (4) Your shoes need grip, but if you have something without socks, that is best, as you swim a lot!
