On Friday mornings in spring join the naturalists from Retzer Nature Center and Benjamin Goss Bird Club members as we set out to discover who’s chirping on the trails. We’ll explore habitats, welcome back spring migrants and check on our year-round residents. Binoculars are available on a limited basis. There is NO FEE for attending and no reservations are needed. Meet in the parking lot.

Lulu Lake & Rainbow Springs

Meet between 5:30-6:00 AM, at the entrance on the east side of Nature Road, 1.3mi south of Cty LO, 1.6mi north of Cty J. This section of the Lulu Lake State Natural area is owned by The Nature Conservancy, and contains numerous high quality natural areas. While looking for migrating and resident birds, we’ll talk some about the natural and human history of this property. Hike will be 2+ miles, mostly on level gravel/dirt trails, though we may venture off trail for short sections. There are no restrooms.

There is a small lot at the entrance, where cars will be directed down the gravel drive for parking further in. This gate will *only* be open for field trip attendees, and close once we start for the duration of the hike. If you arrive after 6AM, or wish to stay for only part of the hike, you may park in the small lot and walk in, or park in the DNR lot about 0.2mi south. Possible post-trip visit to Rainbow Springs.
