While the Lees Ferry site includes interesting old buildings and artifacts from the days when there really was a ferry in operation, nowadays there’s more.
Lees Ferry is also the location where commercial and private rafting expeditions enter the Colorado River to float through the Grand Canyon. To that end, there’s quite a bit of infrastructure. In addition to the usual picnic tables and restrooms, Lees Ferry also features a campground, a dock jutting out from shore, a launch ramp—really a flat beach—at the shallow, gently sloping edge of the river with a thick steel cable for tying up multiple rafts all in a row, etc. There are also a couple of big parking lots packed with vehicles left behind by expeditions on the way downriver.
