We did the Rim to River experience for our son's 12th birthday. It involved repelling down two large canyons, hiking 3 miles, lunch and white water rafting. The group was my husband and I, the birthday boy and our 9 year old twins. Our guide was Dan, who we will always refer to as "Dan the Man". He was INCREDIBLY knowledgeable about everything we were doing and fantastic at making our kids feel comfortable stretching their limits with the canyoneering. The adventure was the highlight of our entire trip. Dan was funny, interesting and smart as can be!
