Because of its complex layout, hikers will benefit from camping in between trails, with most of the backcountry sites offering accommodations.
You can either set up your tent on the shores of Snowmass Lake or along the currents of King Falls, which are located in the idyllic Fravert Basin.
However, this does not mean that these sites are always accessible, as some lie in hidden valleys or at the top of perilous mountains.
For example, the Trail Rider Pass reaches up to 12,000 feet of elevation, which is enough to turn anyone’s legs to jelly. So if you want to explore this trail from AND you’re starting below sea level, it is best to acclimate yourself to the environment before hitting the ground.
For the best experience, we recommend tackling this trail from a clockwise direction, even though you will need to be flexible because of the weather. In most cases, the trails are well-marked and easy to navigate, especially if you own a map and have experience with outdoor exploration.
While the trail is considered difficult, it still remains a popular haunt for experienced hikers, especially those who have the foresight to pack bear spray and other backpacking essentials and protective gear. It is definitely worth the visit and remains the best trail in Colorado.

As the name implies, the Four Pass Loop is a circular trail that takes you through some of the most beautiful landscapes in Colorado.
Because of this, you can begin your hike from two different starting points, which each presents its own unique challenges and experiences.
In most cases, hikers prefer to use the Maroon Lake Trailhead, which is located about 10 miles outside of Aspen.
Unfortunately, the trail has increased in popularity over the years, which means you will need a reservation to start your hike, whether you are driving there yourself or hiring transportation.
When tackling the Maroon Lake Trailhead, there are certain things that you need to consider first, with the most prominent being transport:
- Shuttle Bus: If you are unable to drive to the starting point yourself, you can book a shuttle bus from the Aspen Highlands Ski Area. This shuttle leaves every quarter-hour and is available from 8 am – 3 pm.
- Reserve Permit: Reaching the starting point can be made even easier by reserving a permit for your car, which costs $10 and lasts for 2 nights. This allows you to park at the trailhead between 8 am – 5 pm.
- Call Someone: In some cases, you may be able to call a friend to drop you off at the starting point between 6 am – 8 am. However, you will still need to book a shuttle for when you reach the end.
