El Dorado Platte River Access is a small launch and landing about a mile upstream from where the Platte reaches Lake Michigan. It’s the last landing before Platte Point, and a handy put-in for an easy one-mile float to the lake. You’ll find a boat ramp, a deck overlooking the river, parking, picnic tables and a vault toilet. No food or drinking water is listed at the landing, so arrange those before heading out. If you’re finishing at Platte Point, leave a vehicle at its lot at the end of Lake Michigan Road before you launch. Local outfitters rent tubes and rafts; book ahead for the height of summer.
