A-Basin 101 + Summer FAQ


High Alpine Adventures

Unspoiled. Uncrowded. Uncomplicated. 

Welcome to High Alpine Adventures at Arapahoe Basin, where the spirit of freedom and big mountain challenges create life-altering experiences. Summer at Arapahoe Basin is off the beaten path and at a higher elevation than anywhere else in the area. When people think of an authentic Rocky Mountain experience, this peaceful, natural and rugged place is what they’re imagining. 

A-Basin sits adjacent to the Continental Divide with incredible views, cool temperatures and no crowds—offering visitors a high-alpine, big-mountain experience between 10,780 and 13,000 feet. All activities take place in the trees or on the mountain, putting visitors right in the midst of a stunning landscape covered in wildflowers and visited often by a resident mountain goat herd.

Summer FAQ + Safety

What should I bring to ensure a great day on the mountain?

Our elevation ranges from 10,800 to 13,000 feet where the air is thin and temperatures can drop 10 degrees or more from the base area to the top. The high-elevation sunshine is intense. Stay hydrated to counter the effects of high-altitude sickness but don’t drink untreated water from our mountain streams. Think layers, a rain jacket, sunscreen and water if you plan to be here for several hours. 

NOTE: The aerial adventure park has its own requirements, such as close-toed shoes. Please follow those requirements if you plan to visit.

Please help us follow county health department rules and keep everyone safe by wearing a mask when you cannot maintain physical distancing of 6 feet, when indoors, and when on-site signage indicates a mask is required. Thank you.

What are your COVID-19 precautions? 

We welcome you to join us this summer at Arapahoe Basin, where physical distancing is natural. There are just a few, simple things we ask of you to help keep our guests, our staff and our community safe. ​

Follow on-site signage, stay apart from other groups, practice good hygiene, and have a face covering with you at all times. Tailgating in our parking lots is still strictly prohibited with no exceptions.

If you are using our free amenities, please be thoughtful of others around you when playing disc golf, hiking and mountain biking. Maintain physical distancing, wear a face covering when 6 feet of separation can’t be maintained, and continue to respect both the human and natural environment as you recreate.

You can read about what we are doing to keep our guests and employees safe, here. 

What’s the weather like?

The weather is generally cool, clear and crisp but it can change in an instant so be prepared! Mornings and evenings can be much chillier than mid-day. The temperature at the summit can be 10 degrees cooler than at the base. Afternoon rain showers and/or thunderstorms are common in the summer months and lightning can be dangerous, especially above treeline. Plan to do big hikes or mountain bike rides early in the day. Click here for the forecast.

What can I do with my kids at A-Basin?

This is a great place to go on a wild and natural adventure with your kids. Check out the aerial adventure park, which has “challenge” courses in the forest for little kids all the way through adults.

Get to mid-mountain to explore a beautiful landscape by hiking the Argentine North Fork trail or riding the chairlift. If you’re feeling up to the challenge, continue hiking to the top at 12,500 feet via the service road to look for our resident mountain goat herd. Or, ride the lift to mid-mountain and hike Half Moon Trail for a short but rewarding outing to one of our most incredible vistas. 

Visit our suggested itineraries page for more.

What can I do for free at A-Basin?

Many things! Our hiking and biking trails and disc golf course are free.

What food do you have available?

The 6th Alley Bar & Grill is a full-service restaurant and bar in the base area. The Black Mountain Lodge at mid-mountain offers drinks and light (cold) snacks at the inside bar, which you can enjoy on the scenic deck.

For summer 2020, The 6th Alley is open Thursdays-Sundays, 11:00 a.m. - 4:00 p.m. Opening day for Black Mountain Lodge is Friday, July 3. After that, BML will be open Saturdays and Sundays, only, for BBQ and drinks on the scenic deck, 11:00 a.m. - 2:30 p.m.

Can I bring my dog?

Your dog is welcome in our base area outside of all buildings and on our hiking trails. Our lift is not able to transport animals and they are not allowed inside buildings. Please keep your pet leashed at all times and pick up after them. There are poop bags stationed around the base area for you to use.

What about wildlife?

Foxes, bears, moose, elk, deer, mountain goats, beavers, porcupines and more call the A-Basin landscape home. Please help us peacefully coexist and do not approach, feed or scare the wildlife. Keep the wildlife wild! Moose are aggressive; keep your distance.

How is cellphone service? WiFi?

AT&T is the only cellular provider that works at A-Basin. Free public WiFi is available in the A-Frame lodge, throughout the Mountain Goat Plaza base area and its buildings, and at Black Mountain Lodge at mid-mountain.

Does A-Basin have lodging? 

No, but we are a short drive from the towns of Keystone, Dillon, Silverthorne, Frisco and Breckenridge. Choose from a variety of lodging accommodations—from hotels to condos to full homes—through our trusted partnerships. Click here to visit our lodging page

Can I camp at A-Basin?

No. You may not camp on the mountain or in our parking lots. No overnight parking of any kind is allowed. The pullouts near us on Highway 6 no longer allow overnight camping. We recommend checking out the nearby U.S. Forest Service campgrounds on the Dillon Reservoir or dispersed camping near Montezuma. 

What about marijuana use?

You may not use marijuana at A-Basin. It is illegal to use marijuana in public in the state of Colorado and it is illegal to use it on federal public lands; A-Basin is entirely on U.S. Forest Service land. 

Please help us prevent forest fires! Smoking is prohibited on the lifts and is discouraged on-mountain due to fire danger. No fireworks or campfires of any kind are allowed on the mountain.​

Lift safety

Under Colorado law, you cannot board a lift unless you have sufficient physical dexterity, ability and knowledge to negotiate or to use such lift safely or until you have asked for and received information sufficient to enable you to use the lift safely. You may not use a lift when under the influence of drugs or alcohol. Please lower the bar when riding lifts.
