Great site facilities and location!
The channel marker campsite is the perfect distance (about a half mile on a well maintained flat trail) from the ferry dock and could be accessed by water too! There is a primitive toilet at the site along with a bear pole and storage locker, and a campfire ring with grill top. The site is private yet still close to the trail with an adjacent trail down to the beach, both areas include beaches.
The site requires that all tents are placed within 15 feet of a sign which only grants space for 1 tent easily. We also were able to fit one hammock within these guidelines.
There is provided firewood at most all the other campsites we walked by, but no wood was provided to this site.
Also note the bugs (mosquitoes and flies) are horrendous! Even with strong deet spray. Good idea to invest in the bug net gear the ferry service recommends!
