What a way to start the day

5.00What a fabulous way to spend a morning. Was our first time rafting and our tour guide Kahlee (?) was excellent!!! Was sorry to see this tour end. The other guide (I'm so bad at names) was awesome too, and he shared informative stories with the entire group. Would recommend this for anyone. Thanks for the beautiful morning rafting trip in such beautiful country!!! Is definitely a must do if in the area.
Great rafting experience

5.00My son and I had SO MUCH FUN on this rafting trip. We stopped at a natural hot spring and went cliff jumping (optional of course!). Our guide Johnny was awesome. We would absolutely book with this company again!

5.00Downstream Adventures has a couple engaging, professional, entertaining guides. We went on a pretty calm float trip with a few rapids. We did stop near a cliff where we were invited to climb and then jump into the river. Watching was fun.
Wonderful day on the river with Ody!

5.00Earlier this month my family went on the 1/2 day Upper Colorado rafting trip. We had a large group, 11 people, ranging in age from 5 to 77. Everyone had a blast! Our guide Ody was phenomenal, helping make sure we all had a good time and made it safely down the river. Because we had some kids in our group they were able to fit us all in one boat, although we didn't all have paddles. The scenery was top notch, and it was just the right level of excitement. For those ready for a little more thrill, there is an optional cliff jump! Everyone was ready to go back another time and try the full day trip. If you're looking for a rafting experience, I'd highly encourage you to book with this family run business, and ask for Ody! (Another highlight from our trip, on the drive back to the shop, the driver spotted a black bear close to the road in the trees. We pulled over for a few minutes and everyone had a chance to spot the bear and watch it run through a meadow.)

5.00Our group did the afternoon Upper Colorado, which combines chill floating through gorgeous scenery and a handful of low-level Class III rapids. Dez was friendly and efficient checking us in, and our guide Ody was very knowledgeable about the wildlife, history, and surroundings of the river. We stopped at a cliff jumping spot and many people had a blast jumping off! Highly recommend for a relaxing but fun raft trip.
10/10

5.00We had so much fun on this whitewater rafting adventure! Dez was our guide and she made the experience really fun and also informative. She was so helpful when we decided to jump off the small cliff. (We are seniors) A truly great time!
