This section follows a treacherously steep fireroad down towards Parson's Landing. The dry, gravelly surface seems designed to maximize your chances of slipping and falling. Trekking poles are extremely handy here.
There are two ways to get down to Parson's Landing from this road. If you go to the left, you can follow the road all the way down to the beach. Go to the right about 1/8th a mile and you'll see a trail sign on the left that leads down to the same place.
This was by far the best campground on the island. You are literally right on the sand. Remote, beautiful, and uncrowded. It's also the most primitive. There are weathered old picnic tables and fire grates, but no potable water.
When you make your campsite reservation, it includes a 2-1/2 gallon container of water and one bundle of firewood.
Starlight Beach - Western Terminus of the Trans-Catalina Trail
This remote black sand beach is the western terminus of the TCT. There is no camping allowed, but it's a great place to rest, enjoy the views, and if you're lucky you might catch a glimpse of the bald eagles that live on Catalina.
After you've rested, retrace your steps 4.5 miles back to Parson's Landing.
