This activity is somewhat wheelchair-friendly. There is a paved path leading from the parking lots to the Picnic Pavilion, a distance of about 120'. The Pavilion is near an accessible restroom. We will take a short hike (less than 1 mile) on the Discovery Trail, which has a crushed granite surface.
