Hiking, swimming and picnicking are popular at this South Burlington municipal park. Please, folks, no bikes on the trails.

On 500 acres in Williston, the nonprofit Catamount Outdoor Family Center maintains more than 20 miles of trails for running, biking and hiking. You can take part in organized races or do your own thing.

The views of Lake Champlain, the Champlain Valley and the Adirondacks are breathtaking from this hillock that also happens to be a state park. It’s a short, winding climb to the top — on a road that you have to share with cars, and you have to pay either way — but somehow the exhaust fumes don’t spoil the experience. Must have something to do with all those happy people at the top.
