Hovenweep National Monument is a really nice alternative to the busier and tricker to get to Mesa Verde National Park.
They have old Pueblos and castle ruins strung out along a nice hike. There is a campsite near the visitor centre or alternatively there is BLM land about 5 minutes ride from there. We stayed on the BLM land and headed into the park in the morning. Water and toilets available there and the ranger was really helpful. She let me charge all my devices and kept an eye on our bikes while we wandered around the monument.
The route to get here is very dry but pretty stunning!
