Summer FAQ

Is Arapahoe Basin open during the summer?

Yes! You can visit A-Basin daily between June 25 and September 6, 2021, for many on-mountain activities. Don't miss our new via ferrata, aerial adventure park, dining events, trails, and more. 

Are reservations required for any activities?

Yes, advanced reservations are required for the following paid activities:

  • aerial adventure park
  • via ferrata
  • yoga classes
  • disc golf tournament
  • guided wildflower hikes
  • trail running / mountain biking races
  • all dining events (farm-to-table dinners, supper clubs, beer pairing dinners, and Festival of the Brewpubs)

We also strongly encourage you to pre-buy scenic chairlift ride tickets online. 

Is Black Mountain Express the only lift running in the summer?

Yes, all other lifts are closed until the ski season. Only foot passengers may ride the lift. No pets allowed and we do not offer bike haul. 

When do the hiking and biking trails, and disc golf course, open for summer?

Even though these are our free activities, they do not open until summer operations begin, or when the trails dry (if later than that). Keep an eye on our website as we will update it as soon as these activities are available. These trails close when we start snowmaking operations in late fall.

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 and via ferrata have their own requirements, such as close-toed shoes. Please note those requirements if you plan to visit.

What are your 2021 COVID-19 guidelines? 

As of May 5, 2021, Summit Country, Colorado is currently at the “green” level on its COVID-19 safety dial. All through the winter, A-Basin has followed the guidance of our local public health authorities, and we will continue to do this throughout the summer season. Thank you for helping keep us, our hardworking staff, and each other safe!

Face coverings are no longer required, but are recommended indoors for people who have not been vaccinated. You can read the latest from Summit County Public Health, 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.

Is the tune shop open in the summer?

No. Please see us after winter opening day for your ski and snowboard needs. 

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 cell phone 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 Summit County towns of Keystone, Dillon, Silverthorne, Frisco, and Breckenridge. 

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. Please note that many campgrounds are moving to reservation-only access for summer 2021.

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.


Please note that offerings and event dates are subject to change. The launch of summer operations are conditions-dependent. We have the longest ski season in Colorado.
