Wrote the same review for 3 Bold Coast trails, I don't know them individually. I did the whole loop starting in the lot to the coastal trail, camped at site 2 and returned on the inland trail. The parking lot is a descent size, has a large outhouse. No water available. I arrived at night and slept in the bed of pickup the first night w/o issue.
A few important things to note are the following. No good water available, pools of water are brackish and/or swamp. One stream with a very low flow halfway down coastal trail, which had a dead chipmunk upstream I found out when filtering. I used a filter and sweetwater solution on the stream and swamp water (see picture), didn't get sick but the water will be brown from the swamp. Only 3 campsites, each has enough room for about 2-4 tents or hammocks, first come first serve and they each have at least 1 large mesh outdoor box with a toilet seat on top (site 2 has two of them facing each other if you feel competitive). Light house across the bay to South has a fog horn, goes off every 8 seconds or so. It's a loud low tone and after a while I tuned it out so no problem, if you can tune it out.
The coastal trail is challenging, multiple elevation changes, rocky rooted trail, has amazing view the whole way. It's a combination of on the shore and slightly inland. Halfway is the stream and trail that brings you to inland trail, didn't do that trail. Along the way is a nice pebbled beach accessible down very steep trail, it's a climb to get back up. After looping the South end you go to the inland trail, the growth here is like something out of fantasy and none of my pictures do it justice. Also has elevation changes but easier than the coastal. There are viewpoints along both trails, all but one were worth seeing. Barely any bugs/ mosquitoes and wildlife I saw was all small but heard wolves across the road from parking lot the first night. I will be hiking this again but bring a lot of water plus the filter and solution.
