Cory was great! Friendly, experienced, knowledgeable guide. The kayak and hike were great outdoor activities. Loved the waterfall destination which was well worth the beautiful journey.

Both the kayaking and hike are beautiful! Be prepared to cross streams on foot a few times, but there are plenty of hands available to help if needed.

It is amazing. Our guide Cory went at your pace to make it enjoyable.. It was a bit more challenging than I expected but the pace made it doable and enjoyable..

I’m 63. The hike was more difficult than expected or explained. You have to traverse over a lot of rocks and mud which made me concerned about injury. The kayaking was lovely but also rather difficult for me and my 67 year old husband. Another couple the same age felt the same. I’d leave this experience for the younger crowd.

Sam was the best! Jokester kept us on our toes. Flash flood kept us from getting to the waterfall. Would do it again!

The falls were so impressive! The hike was very muddy with all of the recent storms, but fun to slip in all the mud. My kids loved the adventure. Sam was an amazing and knowledgeable guide! Epic day!

We had a great time on this adventure. I’m an older big gal, but had been prepping for this as it was daughter’s #1 choice for adventure on the Garden Isle. Khaymen was so good at watching out for the safety of myself and the whole group. He was very knowledgeable, engaging and fun and he held my hand thru the rough parts. It was great to see parts of the island that are hidden without the hike. I we loved the kayaking. Almost a spiritual experience. I would go again.

The experience was great. The guide was not aware that the people in the back were having trouble getting through the rocks. I could’ve went without a guide and got more help from friends or people around me. If you ask the guide, he would’ve been unaware that I had fallen and had trouble going through the water.

The hike and falls were amazing. Due to the recent storms the falls were really flowing. We loved it.
