Drive to Park City via Gaurdsman Pass (the only road that continues up and out of the Canyon). Beautiful scenery on the drive, then stroll Park City.
Small lake at the end of the road with a wooden walkway around it. This is an easy walk option and if you come at dusk or dawn you are likely to see a moose.
Donut falls: a family friendly 1.5 mile hike that takes about an hour Circle All Peak: One of our favorites. If you like summits, this has a great view of surrounding mountains. Moderate to hard. Plan for 3-4 hours. Bring water/food. Brighton Lakes: start at Brighton, head for Lake Mary. You can keep going to multiple lakes if you desire. 1.5 to 3 hours. *All within 5-10 minute drive of Solitude, use google/alltrails.com for directions and additional details
