Northeast of Walden, there is a scenic snowmobile route along an old county route, CR8A. The 5 mile ride on CR8A is a marked route from 8,200 feet up to 10,000 feet.
To reach the snowmobile trailhead from Walden, head north on SR125 for 4 miles. Turn right heading east on CR8 for about 7 miles. Park at the intersection of CR8 and CR8A. Continue riding northeast on CR8A along marked route.
Note: the trails are maintained with the assistance of the North Park Snow Snakes Club.
All snowmobiles operating on federal lands within Colorado are required to be registered with Colorado State Parks. This registration permit is available at most National Forest ranger offices and at some chamber of commerce offices. It is highly recommended to purchase the $3 annual Colorado Search And Rescue Card (CORSAR) prior to snowmobiling to help reimburse local search teams should they be needed.
Overall, County Route CR8A is the 24th most popular snowmobile trail of all 24 snowmobiling rides in Colorado.
