Collier Memorial State Park is lodgepole pine over the Williamson River, with the water running past the sites and nobody on the loop in a hurry to break camp. Up the road, the rim of Crater Lake falls away to caldera water so blue it looks dyed, and old snowbanks line the rim road well into June. Klamath Falls families run the week that way round, with the rig parked by the river the whole time and the lake saved for the day.
Collier is on US-97 in the pine country between town and the park, and it earns its place as the base because nothing has to move once you're set up. Every evening ends back at the same site on the same bend of the river, and the day after a rim trip can be another run up the mountain or just a chair by the water while the kids poke along the bank.
Plan the week around the A loop, where Oregon State Parks lists 16 full-hookup sites. The same page carries a maintenance closure notice for the B loop, still posted as of September 2026, and with one loop to count on, the site is the first booking and the rig is the second.
Coming in from the north on US-97, you reach Collier before town and can go straight to your site. From the south, or on a late arrival, Klamath Falls RV Resort off US-97 in town is the easier first night, with full hookups on 30 and 50 amp and pull-through concrete pads. It holds up as a week's base if Collier is booked out, trading the river for being close to town.
Crater Lake from the Fort Klamath side
Rim day leaves the basin on OR-62 through Fort Klamath and climbs through the forest into the park from the south. The first look over the edge is the one everyone remembers, the whole caldera open below you and the water that deep, flat blue. The Park Service permits RVs and tows on all park roads, so a motorhome can make the whole drive.
A travel trailer can stay on its pad at Collier while the tow vehicle goes up. If you bring it along, the Park Service asks drivers coming from Klamath Falls to unhitch at Annie Creek Sno-park, 5.5 miles north of Fort Klamath on OR-62, and it warns that Rim Drive and Pinnacles Road are narrow with no turnarounds for large vehicles.
The loop around the rim is Medford's Rim Drive trip, and a two-person crew set on driving every mile of it can size down to an Oregon campervan. For a night inside the park at Mazama Village, plan it from Medford.
Rocky Point on Upper Klamath Lake, and Lake of the Woods
The back half of the week moves the rig once, from the pines at Collier to Upper Klamath Lake. Locals treat the lake as a weekend habit, and at Rocky Point it stretches into a week without trying. Fishing boats head out from the resort in the morning, the wetlands along the shore fill with marsh birds, and the rig stays put while the days go to the water.
Rocky Point Resort has RV sites with full hookups and partial ones on 30 amp and water, and its RV and tent sites close for winter. Lake of the Woods Resort rents cabins as well as RV sites, which suits a group split between the rig and a cabin.
One day of the lake week belongs to Lava Beds National Monument, over the line in California. Trails drop into black basalt lava tubes, and the air at the cave mouths comes up cold even on a hot afternoon. Go down for the day and sleep back at the lake.
