The Big Blue Trail is a major access route to the Uncompahgre Wilderness. It begins one half mile south of Big Blue Campground at approximately 9,670 feet. The trail follows Big Blue Creek for eleven miles through Engelmann spruce forest and parks to an approximate elevation of 11,440 feet. The trail splits at this point with the left fork continuing as Big Blue Trail. It leads one and a half more miles to end at the intersections with Ridge Stock Driveway, 233. Big Blue Trail offers spectacular views of peaks over 13,000 feet. The fishing in Big Blue Creek and Slide Lake is good.
