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

Our family really enjoyed the Aspen Mountain snowshoe tour led by Rose. The scenery was amazing and Rose was a very engaging guide, and very knowledgeable about many aspects of the area’s biology, geography and history.
