Even a federally endangered dragonfly has its natural habitat at the Ridges and may soon be the subject of a federal study. The trails are open from sunrise to sunset year-round. Organized groups must call the sanctuary before visiting. No pets, strollers or bikes are allowed on the trails. The sanctuary currently has over 3,000 members who are eligible to participate in special workshops and educational seminars, including summer programs for children.
Membership is acquired through registration and requires the payment of annual dues.
Yet another outdoor adventure suitable for families or individuals, bike riding, can be found at Peninsula State Park. Two businesses conveniently located near the start of the Sunset Bike Trail will rent multiple styles of bikes for very reasonable rates. The Sunset Trail has multiple loops and riders can tailor the distance of their ride. Nor Door is located on highway 42 in Fish Creek. Still another idea for adventure comes from The Inn at Kristofers in Sister Bay.
