Activities, Aspen Events, Snowmass Events | 0 Comments

In the Aspen valley, there’s plenty to do at any time of year, but September is quite special. Once the summer tourists have departed and before the skiers arrive, you’ve got the perfect opening for a vacation that’s filled with fun, but without the frenzy.  

Many of Aspen’s September activities take place on an annual basis; that said, some years experience interruptions in planned events. While our list of September favorites is meant to be a great guide, you’ll want to confirm specific dates and times before cementing your plans. 

Aspen September Activities

The Lost Forest in September

You can experience the Lost Forest at Snowmass each weekend (Friday through Sunday) during September, balancing the adrenaline with relaxation due to smaller fall crowds, cooler temps, and calming color changes. You can choose a mellow adventure visiting ponds, creeks, and hiking trails — or chase bigger thrills with the alpine coaster, ropes adventure course, zipline, and a climbing wall. 

Snowmass Bike Park

Bring your own mountain bike or rent the latest models at Snowmass Bike Park to experience September’s splendor on singletrack among and around the evergreen forests and aspen groves. You can ride the Elk Camp Gondola with your bike and cover up to 25 miles of downhill biking trails while descending nearly 3000 vertical feet — all the fun with much less effort!  

September Birding in Aspen

ACES (Aspen Center for Environmental Studies) offers weekly morning birding sessions led by a guide for those who’re interested in the local seasonal birds. Birders of all levels are invited to attend the sessions at Hallam Lake Nature Preserve (in downtown Aspen) or Rock Bottom Ranch (downvalley in Basalt). Attendance requires advance registration and a $25 fee for non-members. ACES does, of course, welcome new members; membership provides event discounts, as well as support for an organization committed to protecting our natural resources.   

September Farm Tours

If you’re curious about local seasonal farming practices, you can head downvalley to Basalt most days of the week to experience a midday farm tour of Rock Bottom Ranch. Learn about  the animals and gardens while being introduced to scientific vegetable production and the benefits of a rotational livestock grazing system. Donations are suggested.
