Seven environmentally wondrous areas of Ozaukee County will be open for eco-tours from 9 a.m. to 3 p.m., June 14, during the fifth annual Treasures of Oz event. The outing allows explorers to download a visitor’s passport and tour the Cedarburg Environmental Study Area, the new mountain bike park at Pleasant Valley Nature Park, the Ravine and Beach Natural Area at Lion’s Den Gorge Nature Preserve, the hiking trails at Mee-Kwon Park, the U.S. Fish and Wildlife Service Belgium Waterfowl Production Area and the Trinity Creek Wetland Area.

The outing wraps up at Forest Beach Migratory Preserve, where from noon to 6 p.m., participants can observe the 5-tar bird hotel, sample food and enjoy music, displays, live animals, raffles and a silent auction.

Wildlife experts and guest speakers will be present at each location, acting as docents and giving informational talks. Visitors can attend all or some of the sites open to the public that day, and passport stamps can be traded in for free raffle tickets.
