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

I took their sunset beaver hike and greatly enjoyed the experience! The tour began with an informative session about beavers, in which the kids in attendance got to dress up as beavers. It was adorable! Then, we took a short hike around Hallam Lake and spotted a beaver carrying a branch to construct his dam! It was great! There are... More

Love to visit with my grandchildren ages 6 and 8... It's a unique opportunity to learn about the natural habitat of local birds and wildlife.. Be sure to bring your camera... Best shoes are light hikers... But anything will do. Indoors there's a stuffed mountain lion - and lots of learning stations with snakes etc... outdoors there's an eagle and... More

This was a nice surprise and it's free plus very user friendly. Nice short hike around nature ponds but highlight as the golden eagle and great horned owls.

ACES is just north of downtown Aspen so if you are staying in the city it's best to walk there as parking is limited. It's a great place for kids as there is a golden eagle and great horned owl to view as well as nice walking paths around the small lake on the property. While admission is free, make... More

Since I gave up downhill skiing a few decades ago, I look for hiking, cross country skiing, and snowshoeing opportunities whenever I'm on a winter vacation. ACES offers snowshoeing opportunities on Aspen Mountain, at Snowmass, and in Ashcroft. All of these were headed by brilliant, thoughtful, passionate about the environment, energetic guides. They took me into areas that I never... More
