The Treasures of Oz Eco-Tour, held on June 16, is a free, annual, family-friendly event that celebrates the abundance of nature throughout Ozaukee County. The focus for 2018 will be Ozaukee’s “Other Coast”— the portion of the Milwaukee River that runs through the county.

This year’s adventure will feature seven nature sites, all opening at 9 a.m. and closing at 3 p.m., except Forest Beach Migratory Preserve, the host site, which will close at 4:30 p.m. The preserve will hold a celebration with exhibits from environmental organizations, music by Steve & Friends, a raffle, a silent auction, and food and beverages.

The other six sites on this year’s Treasures of Oz Eco-Tour are Bike Path Island; Bratt Woods; The Ozaukee Interurban Trail; Riveredge Nature Center; Hawthorne Hills HH Peters Camp and Shady Lane State Natural Area; and The Milwaukee River Watershed Fish Passage Program, in Thiensville Village Park. People can attend all of the sites or just the ones in which they are interested. Experts will be on hand at most of the sites to discuss conservation measures, wildlife and related subjects.

Participants can download a passport from the website and collect stamps and trading cards at each site. Passport stamps can be exchanged at the Forest Beach Migratory Preserve for free raffle tickets. Cyclists will receive double stamps.

Location: 4970 Country Club Rd., Port Washington. For more information, site locations and to download the passport, visit TreasuresOfOz.org.
