Paddlewheeler Boat-In Campground is a Colorado River boat-in site within Picacho State Recreation Area near Winterhaven, California, featuring two large campsites designated exclusively for boater and canoe campers with picnic tables, fire rings, and chemical toilets.

Access is by boat only with no vehicle parking allowed at the site, and campers must self-register upon arrival on a first-come, first-served basis with minimum boat fees applying.

The site offers no potable water, so visitors must pack in all supplies and pack out all trash.
