The proper Little Cultus Lake Campground has a bunch of sites but only a few on the water and not really worth the $ unless you get a site on the water. If you turn right instead of going left towards the campground, there are around 5-6 dispersed sites right there on the corner plus an amazing single site about 1/2 mile down that road, right on the lake. No cell service, rough roads, but amazing views right on the water of Little Cultus Lake. One of our favorite dispersed sites. For even more remote dispersed camping you can drive up to Irish and Taylor Lakes that have beautiful dispersed sites on the water but the road up is rough rough rough, not suitable for anything but a high clearance 4x4. About an hour from Bend.
