From the moment we walked in, I knew we were in good hands. I have been rappelling for more than 30 years and done "unsupervised" canyoning in Mexico for years. The equipment was first rate and in good condition, the training was appropriate for the new people. We had 3 guides for the first half, which was the easier part. The highest jump was only 20 feet, but if needed, you could rappel it. Everyone was belayed for safety. For the second half of the trip, it was just my husband and I and two guides. This was the more difficult half and ended with a 200 foot rappel in a raging waterfall. If you have never rappelled in a waterfall (I have) it is quite intense and not for people with any fear of heights.
Do make sure that you have hiking boots, short ones are fine. Tennis shoes MAY survive the trip.You want something with a tread. Do not wear shoes without laces; they will come off which you really do not want.
This was a blast! Take a waterproof camera. No cellphone will survive the rip. They will rent you a go pro if you want one. The guides are awesome!
