Frequently Asked Questions

Is the Buttermilk Mountain Trail suitable for beginners, or are there different difficulty levels?

The Buttermilk Mountain Trail offers a 'choose your own adventure' experience. While the overall trail is rated as moderate, you can opt for a challenging, direct single-track route with significant elevation gain, or a more leisurely, winding path along the Buttermilk Summer Road. The latter is a good intermediate option for a more relaxed pace.

How long does it typically take to hike the Buttermilk Mountain Trail?

The average duration for hiking this trail is approximately 3 hours and 23 minutes, covering a distance of about 10.2 kilometers with an elevation gain of nearly 586 meters. Your actual time may vary depending on your chosen route and pace.

What kind of views can I expect from the summit of Buttermilk Mountain?

From the summit, you'll be rewarded with jaw-dropping views that are considered 'second to none'. You can look directly at the iconic Maroon Bells and Pyramid Peak. Along the way, you might also encounter the Viewing Platform on Buttermilk Summer Road.

Is the Buttermilk Mountain Trail dog-friendly?

Yes, the trail is dog-friendly, making it a great option if you want to bring your canine companion along for the hike.

What is the best time of year to hike Buttermilk Mountain Trail?

The best time to hike is generally during the summer and fall months when the snow has melted and the weather is favorable. The lifts do not operate in the summer, so you will need to descend on foot.

Where can I park to access the Buttermilk Mountain Trail?

Specific parking information isn't detailed, but access to the trail typically begins from the base of Buttermilk Mountain in Aspen. It's advisable to check local Aspen parking regulations and options before your visit, especially during peak seasons.

Do I need a permit or pay an entrance fee to hike Buttermilk Mountain Trail?

The Buttermilk Mountain Trail is located within the White River National Forest. Generally, day-use permits are not required for hiking in most areas of the National Forest, nor are there entrance fees for the trail itself. However, always check the latest regulations from the US Forest Service for any updates or specific area requirements.

What is the terrain like on the trail, and should I be prepared for sun exposure?

The trail is generally a dirt path. You can choose between a narrow single-track route or the wider Buttermilk Summer Road. Much of the hike is exposed, so it's essential to bring and apply sunscreen to protect yourself from the sun.

Does the trail intersect other well-known paths?

Yes, the route incorporates sections of several other trails. You'll find yourself on parts of the Buttermilk Summer Road, Buttermilk Access, Government Trail, Buttermilk Access Road, and Bandit during your hike.

Are there any specific strategies for hiking Buttermilk Mountain to manage difficulty?

Absolutely. For a challenging 'lung-busting workout,' take the narrow single-track trail directly up the mountain. If you prefer a more moderate and conversational pace, follow the Buttermilk Summer Road, which winds its way to the top. This allows you to tailor the hike to your fitness level and desired experience.

What should I bring for a hike on Buttermilk Mountain Trail?

Given the exposed nature of much of the trail, sunscreen is essential. Additionally, bring plenty of water, appropriate hiking footwear, layers of clothing for changing weather, and snacks. Since you'll be descending on foot, ensure you have comfortable gear for the entire round trip.
