Juneau County has tapped into the rail-trail phenomenon with a 13-mile trail running south from Camp Douglas to Elroy. Anyone who has traveled Interstate 90/94 will remember Camp Douglas - home of the remarkable sandstone bluffs that tower over the four-lane. Nearby, Mill Bluff State Park offers the opportunity to get "up close and personal" with several of these glacial monoliths. Bike campers will find 21 campsites there as well as a small pond for swimming. Camp Douglas is also the home of Volk Field and the Wisconsin National Guard Museum. A short bike tour of the base passes many static displays of vintage aircraft. You can also tour the museum whose exhibits chronicle the history of the Wisconsin National Guard from its inception following the civil war to the present. The Omaha Trail runs south to Elroy where it joins the Elroy-Sparta and "400" State Trails. On the way you'll visit the quaint village of Hustler, then roll through a tunnel, the only other trail tunnel in the state besides those on the Elroy-Sparta Trail. The Omaha Trail tunnel is short; less that two blocks long, and not too intimidating for kids or claustrophobic adults. Just think of it as "tunnel training camp."
