Parking

This is where visitors get caught out. Parking is allowed only in the designated lots along Shep Jones Lane.

Trails

Avalon has about 5 miles of trails, with an interactive map on its website. The preserve asks visitors to stay on the trails, tread lightly and treat the plants and animals as hosts: "Observe, Don't Disturb."

Dogs

Dogs are welcome. They must be leashed at all times, and owners must pick up after them. That makes Avalon a good dog-friendly alternative to Sunken Meadow, where pets are barred from the main park. See dogs at Sunken Meadow.

What Not to Expect

Programs
