Overview Fantastic trail with plenty of challenges, wildlife and scenery. Loud Thunder is one of the best kept secrets in this area. This is a must do if you are in Rock Island County.

Really more than the two miles posted. If you calculate you are over twelve miles easy. In went this fall and did get to see an eight point buck cross in front of me. Steve McAtee (172) 11 months ago N/A: 3 Completed 3 Reviews Good trails which have a lot of up and down going around the lake. However, the trails are more deer trails and are not too developed. However, there is good fishing in Lake George.
