★★★★★Took a snowshoeing adventure today! Sam was our guide. He was friendly and we really enjoyed him sharing his passion for what he does and the space we were exploring! Great way to start the day!

★★★★★My boyfriend and I went snow shoeing with ACES one afternoon last month. Grace was our guide - it was obvious she was very well versed in the local plants, animals, geography, etc. A great way to spend a morning or afternoon!

★★★★★The Hallam Lake reserve is incredibly poetic, especially when the sun sets behind the snow-covered bushes

★★★★★Highly, highly recommended. I walked by Jacob B. at Maroon Bells Wilderness and he was hyped about beavers. Very knowledgeable and he mentioned that this "ACES" has a "beaver walk". So, we all signed up and, when we arrived, we met with Mason M. and Rose W. who were both knowledgeable, professional, and friendly. Rose went out of her way to include a shy, young girl into the experience. It was so much fun. Mason knows a lot about wildlife and I appreciated his enthusiasm.
