2. Hike or Bike on Kid-Friendly Trails
The Keystone area is filled with beginner-friendly trails perfect for little legs (and strollers). Top picks include:
Snake River Trail – a paved, riverside path ideal for walking, biking, or stroller-friendly outings
Sapphire Point Overlook (near Dillon) – short, scenic loop with sweeping views of Dillon Reservoir and plenty of spots to stop and explore
Dercum Summit Hiking Trail – a popular summer-time hiking trail at the top of Keystone Resort. There are signs near the KeyTop Overlook Deck that mark where to go to find the trail. A fun 2.2 mile loop that is considered an easy route.
Families with bikes can also explore Summit County’s extensive Rec Path system, which connects Keystone to Dillon and Frisco for longer rides or fun day trips.
3. Explore Keystone Lake
In the summer, Keystone Lake transforms into a peaceful playground for all ages. Families can rent paddle boats, walk the lakeside path, try their hand at fishing, or simply relax and watch the ducks. There are plenty of grassy spots for picnics, and the surrounding views of the Rockies make it one of the most relaxing family-friendly things to do in Keystone. Step inside the Rathbone Taproom where parents can have a cold one and kids can play in the arcade zone!
Turn a simple walk into an exciting scavenger hunt by exploring Keystone’s forests and meadows on a nature walk. Keep an eye out for marmots, chipmunks, deer, and even the occasional moose. The Keystone Science School often offers family-friendly programs or nature camps during summer months—ideal for curious young explorers. You can also book “Adventure Trips” with them, ranging from sandboarding to rock climbing.
Bring binoculars, a camera, and a field guide to make it an educational (and fun) activity!
5. Day Trip to Dillon Marina
Just 15 minutes from Keystone, Dillon Marina is a fantastic place to spend a summer afternoon. Families can rent kayaks, canoes, paddle boards, or pontoon boats, or simply enjoy the marina’s playground and walking paths.
