When you head out to the trail, park at the Rogers Pass Trailhead, which is also known as the James Peak Trailhead. There is a dirt parking area off the road that sits on the top of a cliff overlooking an old bridge and the valley below. There are no amenities, so be sure you bring water and clean up bags for the journey.
You and Fido will begin your hike on the trail that travels south as it enters the alpine forest. Tall trees line both sides of the trail, offering shade and a cool breeze for hikers to enjoy. One of the best parts of this hike is that dogs do not need to remain on a leash and can walk and hike freely with you as you climb the ridge. After about 3/4's of a mile, you'll leave the safety of the shade and enter the desert foothills of the mountain ridgeline.
As you ascend the ridge, you'll notice sharp limestone rocks and desert terrain that contrast with the green forest down below. The sharp inclines don't last long as you begin to get on top of the ridgeline, walking along Roger's Pass on the top of the ridge. On the east side of the ridge, you'll see the valleys below, with one hosting Heart Lake.
The trail stops at the ridge, and heading down will be easier for you and Fido, although be sure to watch your step as you climb. The blue Colorado sky and green forests of the state make for some pawsome scenery, ensuring that you and Fido will love the Rogers Pass Trail.
