Take a look at the area photos for Mazama and you will see a map of established campgrounds in the area and also options for dispersed camping. The Yellowjacket or Goat Creek Sno-Parks are good options for free dispersed camping as there are toilets and only a short drive from the trailhead. Please do not camp at the Goat Wall Parking area - locals have raised serious concerns over the impact of climbers camping here.
