Reviews: Estes Park Guided E-Bike Tour

It was even more fun than we expected! We saw so many beautiful views & took lots of photos. Our guide was great & very informative. We saw LOTS of elk which was super cool too!

Reviews: Discover Rocky Mountain National Park

Guest User2024-08-29

The group was small and intimate and very friendly. The day was storybook beautiful. Each stop was enjoyable and unrushed. Our guide, Aaron, was knowledgeable, fun and just a delight. We were so "enamored" with Aaron, that we thought of snatching him at the end of the tour, and stuffing him in our suitcase, and make a run for it. Then my cousin reminded me that kidnapping was a federal offense and by coincident, there was a Federal Supermax prison in Colorado. We reluctantly abandoned the idea.
