This centre does free guided mountain tours on Snowmass explaining the wildlife and environment. With helpful well informed guides we were surprised more people did not take up the offer. Free tours in the morning or afternoon, lasting about an hour giving you a great introduction to the mountain and taking you on runs you might not otherwise find. You... More

Recommend the very interesting snow shoe tour on aspen mountain. You hike over the back and away from the crowds where you gain a very different appreciation for the mountain. A great option for a day off skiing.

I really enjoyed this walk. The guide gave us a lot of really interesting information, particularly on identifying animal tracks and fir vs spruce trees. The views were stunning too. I have isited the Centre in past years and enjoyed that too.

I signed up the family for a 4 hour snowshoe tour to Ashcroft Ghost Town after quizzing my daughter and her girlfriend on which snowshoe tour they wanted to go on. The other options were Snowmass and Aspen Mt. A ghost town and lunch at the famous Pinecreek Cookhouse made it an easy decision. The "hike" was amazing and Phoebe... More

If you have a few hours, visit the ACES area. There is a self-guided walk around the property with birds to see, including a Golden Eagle which has been there for 30 years. The staff are really interesting and helpful if you have questions

I love walking the streets of Aspen...such great treats in terms of food, stores and what not....but it can be crowded with people and cars....this little preserve on the edge of town is in walking distance of most of the major hotels...it is simply magical with creeks, lakes and wildlife...a real place for renewal....don't miss it...

Went to ACES last week with a group of friends in town for a conference. What a wonderful way to take a break from the "grueling" schedule of panels and activities! The trails are fun and calm vibe of the place just what you need to remember to pay attention to the beauty in nature. ESPECIALLY in Aspen!

Great welcoming crew always at the door. They always offer a backpack to borrow while you tour the grounds. A few books to guide you through, keeping a 2 and 4 year old's attention no problem!

There are several spots around the ski mountains where you can walk up and someone from the ACES will be there to take you on a "guided tour" of some trails that lasts anywhere from 45 minutes to 2 hours, and is easy to navigate with sneakers and a bottle of water. Worth the time for a different view of... More

We went on four ACES hikes: Snowmass nature trail, Ice Age talk, top of Aspen, and Maroon Bells. All of the tours were good, but the first (with Matt; Emily and Elliott were our other guides) was the best. Matt's love for his job is palpable. He made everything fun, informative and exciting. We recommend these tours (they are free... More
