Four Pass Loop (This Hiking Trail Should Be at the Top of Your List)

Do you look to explore the great outdoors? If so, then you should pay a visit to the Four Pass Loop, which remains one of the most beautiful hiking trails in the world. 

In the following guide, we have outlined some important information concerning the West Maroon to Buckskin trail and what you will need to begin your journey. 

Basic Information

• Location: Mountain West (Maroon Bells-Snowmass Wilderness, Central Colorado) 
• Distance: 28 miles 
• Days To Complete: 3 – 4 
• Physical Level: Difficult 

The trail features 7752 feet of cumulative elevation gain, with most of the trail rising above the treeline and causing open exposure. 

• Logistical Level: Difficult 

Because of its high elevation, the trail is susceptible to thunderstorms and harsh weather conditions, which means you must plan your route before attempting to cross the mountains. You will also need a self-serve permit and access to a cross-country vehicle to access the trailheads. 

• Best Season: Summer – Fall 
• Average Elevation: 11,000 feet 
• Elevation (Starting Point): 9580 feet 
• Maximum Elevation: 12,500 feet

What Does It Offer?

Despite its challenging terrain, the Four Pass Loop rewards hikers with some of the best views in the state, which cover mountain vistas and sweeping landscapes. So if you want to experience the natural world from above the trees, this is the place for you. 

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. 

How Do You Reach It?

• Nearest Cities: Aspen (10.8 miles) – Crested Butte (14 miles) 
• Nearest Trails: Maroon Lake Trailhead (starting in Aspen) – West Maroon Trailhead (starting in Crested Butte)

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 their 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. 

When Should You Visit?

Like most hiking trails, the best time to visit the Four Loop Pass is in the summer, as this season yields the best weather. Because of its high altitude, you will still be able to see now well into June, as well as experience the natural scenery and wildlife. 

Despite this, it is still possible to visit the trail during the Fall, although the weather conditions could make the overall experience more treacherous. 

Planning Your Hike

When traversing the Four Loop Pass, it’s recommended that you write out an itinerary for the duration of your hike. In most cases, a solid itinerary should look like this: 

• Day 1: West Maroon Pass (12490 feet) to Frigid Air Pass (12405 feet) = 14 miles to the campsite 1. 
• Day 2: Trail Rider Pass (12415 feet) = 8 miles to campsite 2 at Snowmass Lake. 
• Day 3: Buckskin Pass (12462 feet) = wake up early and journey over the mountain pass in time to reach the shuttle.
