Great hike. So glad we booked this tour with Viator, this hike was located a little outside the city and having a local guide to navigate us to/from made it an easy day. Rory, our guide, was awesome. Prior to the trip he helped me plan ahead and even after the hike was kind enough to give us tips for the rest of our trip. My girlfriend and I are in pretty good shape and it took us about three hours when we reached the loop we opted to hike up one side and then down thru the waterfalls. Definitely was a workout both ways but the multiple falls were beautiful and we enjoyed our time. Pack some snacks and water as it's a solid workout and you'll likely need some fuel. I'll say it again though, Rory was awesome, really knew the trail and clearly loves being out in the trails.
If you are in Hong Kong and enjoy nature an physical activity this tour is a must. Rory is a wonderful guy and a superb guide, he will take you to places he knows perfectly and give you a very nice experience.
