42 min drive Red Rocks Amphitheatre: https://www.colorado.com/articles/red-rocks-amphitheatre-6-things-see-do

Fossils at Red Rocks: Red Rocks Amphitheatre’s 300-foot walls unintentionally document the 16-million-year history of the region. Don’t miss the fossil fragments of a 40-foot sea serpent, a marine reptile and flying reptiles. Dinosaur tracks from the Jurassic period can also be found in the park surrounding the theater. Of course, the Red Rocks’ stone formations are standalone attractions. While some formations tilt backward, others slope as much as 90 degrees. The amphitheater’s two main stone slabs, dubbed “Ship Rock” and “Creation Rock,” are taller than Niagara Falls.

38 min drive: Dinosaur Ridge Some of today’s most notorious dinosaurs were first discovered in Dinosaur Ridge near Morrison. Since these first-in-Colorado finds, Dinosaur Ridge has become one of the world’s most famous dinosaur fossil localities. Today, you can take daily self-guided and guided tours of excavation sites and exposed fossils. For a special treat, the road is closed once a month for Dinosaur Discovery Days, when you can take guided tours to view the tracks, bones and other spectacular examples of geology and paleontology without the distraction of passing traffic.

2 hr 14 min drive/way: Rafting, $90/person: When you picture iconic river rafting throughout the west, this family friendly rafting trip comes to mind: large roadless sections of river; the California Zephyr train going by as we descend through a couple moderate rapids; soaring eagles, jumping fish, and amazing scenery. This tour is one of the best scenic float trips in Colorado and one of the most enjoyable river trips in the Western US. The minimum age for participants is about 5  years old, based on current water conditions but that fluctuates during the season depending on water levels.  You can expect the tour to last approximately 4  hours on the water with stops along the way at a natural hot springs and cliff jumping. This trip is a wonderful opportunity to get the whole family on the river to enjoy easy rapids, beautiful scenery and plenty of peace and quiet. Our price is based on a 5-person minimum. All of our trips begin by meeting  us at the put-in south of Kremmling, CO. https://coloradowildernessridesandguides.com/product/raft-upper-co-river-1-2-day/
