Confluence Park Access is a free, day-use-only BLM site located on the south bank of the Colorado River at the confluence with the Blue River near Kremmling, featuring a rail boat launch and accessible vault toilet.

This is the primary put-in location for Class IV-V+ whitewater in Gore Canyon, an extremely dangerous expert-only section—note that camping is prohibited and trash services are not provided (pack out all waste).

Access via Highway 9 south of Kremmling, then Trough Road approximately 1 mile to the access road.
