We had a great raft trip with Alex. Our guide was kind, trustful, and funny. Our daughter said I had so much fun on our first raft trip I can't wait to go again.

Yet another great trip with River Runners on the Arkansas River - this time we did Numbers and it was great. Our guide, William, made the trip so much fun and safe. He knows the river well and guided us down through great rapids and twists and turns that were a hoot! Safety is their top concern, then it's all about a great experience. Their location is easy to find and great location for put in and pull.

This was a second rafting trip this season. We always go back to River Runners. We did the Big Horn Sheep half day trip. Our guide was Sam. She did a great job making the trip a memorable trip for our two grandchildren. The family is already planning to return next year. Thank you for a fun day!

4 people had an awesome time with Travis, Megan and Seth on 7/5. Actually did numbers full day. Have done both- do the full day. 1/2 day is too short and you won’t want to stop. It’s like driving a Ferrari through a forest while being sprayed with super soakers. I just giggled. Not for kids. It’s serious water.
