We are traveling for a two year old and a six year old this summer staying in Estes Park and would love suggestions. Not more than an hour or two drive would be great!
Lily Lake and Bear Lake loops are both easy hikes and stroller-friendly. Look for the cool salamanders in the water at Lily Lake. If your two-year old is tall enough, you could try the new "Mustang Mountain Coaster": https://www.mustangmountaincoaster.com/passes-best-mountain-coaster/
