We took our 17 month old twins there this week for their first sledding experience. There were sleds there for our use (left by others who couldn’t take them on the plane, I guess!), snow was slippery, and we had a great time.
They even have rails for the “older” kids. Check out this 2 & 1/2 year old sledding over the rail (bottom right).
How to find it? Go to downtown Winter Park (arriving from the resort/Denver side), go to the 2nd stoplight and take a right (at the Chamber Of Commerce). Park and walk up the stairs to the park area and top of the sledding hill.
