Looking for a rafting company out of or near Breckenridge for June. We have a 10 year old and 12 year old so must be family friendly.
If you want close to Breckenridge, try Glenwood Canyon rafting. I think there is also one in Frisco, which is even closer, but I have never tried them (check reviews).
I am more fond of the Royal Gorge trip, when it is safe to do it, but that is a hike. If so, try Whitewater Adventure Outfitters or Royal Gorge rafting. It has been a few years since I have been in Colorado, so check reviews. Most of the companies are good though.
