Illinois > Alto Pass
Bouldering is on Private Property
Boulders located 50 feet on the downhill side of the trail are on private property. Although access is currently not a issue (11/15/17), please do your part to ensure it remains that way.
Although Alto Pass is known as a great place to begin sport climbing outdoor, several fun boulder problems exist as well.
