Join us for the Illinois River Watershed Partnership’s “Tour De Cave” Bike Tour with two bicycle rides along the scenic back roads of Cave Springs. A leisurely 4-mile, family friendly ride begins at 9:15 a.m., and a fast-paced 12-mile endurance ride starts at 9 a.m. Both tours will be led by IRWP staff. Complimentary lunch will be provided afterward. Stick around the Watershed Sanctuary in the afternoon for the Geo-Quest Challenge and a chance to win a GoPro HD Hero3 Black Edition camcorder.
