Pick up and drop-off at our hotel which is super convenient. There were 7 people in total (not including Tu, our guide). It felt like a good number of people, not super crowded. The other people participating were all nice and friendly. Tu was a great guide. I think if you want to do jumps it's nice to have someone who goes frequently and knows where you should (and can) jump from. Tu showed us how to modify our jumps for people who were less comfortable (like myself). I would recommend hiking sandals (although you'll likely get sticks and rocks in your sandals) or shoes. You will have to get into waist-high waters at one point so keep that in mind. If you have a waterbag that's perfect for this trip. This was a great alternative since we couldn't swim in the sea (wind and waters were too rough during our stay). Highly recommend! Oh, I loved the chicken rice joint we stopped at for lunch after the waterfalls.
