May in Breckenridge and across Summit County is what locals affectionately call “mud season”—but don’t let the name fool you. This time of year has its own charm, offering a quieter, more relaxed mountain experience paired with unique events, spring skiing, and the first hints of summer.
If you’re visiting (or lucky enough to live here), May is all about slowing down, soaking up the sunshine, and enjoying the mountains without the crowds.
Spring Skiing & Closing Day Celebrations
One of the biggest highlights of May is squeezing in those final ski days of the season. Resorts like Breckenridge Ski Resort and Copper Mountain typically stay open into early to mid-May, with projected closing dates around May 10 (conditions depending).
Spring skiing here is less about powder days and more about the vibe—think soft snow, sunny patios, and a festive atmosphere. Closing weekends often feel like a celebration of the entire season, with costumes, music, and that unmistakable “last lap” energy.
If you’re not quite ready to hang up your skis, Arapahoe Basin Ski Area is known for its extended season, often staying open into June thanks to its high elevation.
Live Music, Events & Spring Vibes at A-Basin
Throughout May, Arapahoe Basin Ski Area transforms into one of the most fun spots in the county. The base area—nicknamed “The Beach”—becomes a hub for live music, après gatherings, and laid-back spring energy.
Events and concerts run throughout the season, bringing together locals and visitors for sunny afternoons on the mountain.
Toward the end of the month, one of the most anticipated events is Pride Weekend (May 30–31, 2026), featuring DJs, live music, and a full weekend of celebration on the slopes.
The Start of Summer Activities
While ski season winds down, summer activities begin to slowly ramp up across Summit County.
In Keystone, golf season officially kicks off in May with opening days at two popular courses. The River Course is expected to open around May 8, followed by Keystone Ranch Golf Course on May 15—marking one of the first signs that summer is just around the corner.
It’s a fun time of year where you can truly experience both seasons in one day—ski in the morning, then enjoy patio dining or even a round of golf in the afternoon.
Trail Running & Outdoor Events Return
As the snow begins to melt at lower elevations, trails start reopening for hiking, biking, and running.
The Summit Trail Running Series kicks off in May and runs throughout the summer, offering races for all levels and a great way to explore the area’s scenic trails.
Even if you’re not racing, this is a beautiful time to get outside—just be prepared for mixed conditions. You might encounter anything from dry dirt to snow patches depending on elevation.
Local Volunteer & Community Events
May is also a big month for community-driven events across Summit County.
On May 16, the Keystone Science School hosts a Spring Volunteer Day, where locals gather to help prepare the campus for the summer season. Later in the month, on May 30, the Keystone Town Cleanup Day invites residents and visitors to give back by helping clean up trails and public spaces after winter.
These events are a great way to connect with the community and experience the local side of Summit County.
Memorial Day Weekend in the Mountains
Memorial Day weekend is one of the livelier times in May and often marks the unofficial start of summer in the mountains.
While still quieter than peak season, you’ll find more restaurants reopening, more events popping up, and a noticeable shift in energy as the county transitions into summer mode. It’s a great weekend to visit if you want a mix of activity and breathing room.
What to Expect in May
May is a bit of a transitional month here, and that’s part of its appeal.
You’ll find fewer crowds, better availability at restaurants, and a more local feel throughout town. Some businesses may have reduced hours as they take a short break between winter and summer, but that slower pace is exactly what many people love about this time of year.
Final Thoughts
May may not be the busiest month in Breckenridge, but it’s one of the most underrated. Between spring skiing, community events, and the return of warm, sunny days, there’s still plenty to enjoy.
If you don’t mind a little mud and a lot fewer crowds, you’ll get to experience Summit County in a way that feels more relaxed, more local, and just a little bit special.
