One of my favorite camping islands in the San Juans.
The main camping area is located at the west end of the island near the cove between Patos island and Little Patos island. At the east end of the island there are a couple of small coves that you can anchor in, but there are no campsites on the east end of the island.
I have been coming to Patos Island for over 20 years, and it has changed very little in that time. Sure they have installed new vault toilets that are much nicer than the old ones, and the old dock that was quite unstable has been torn down. The old military barracks that were out by the lighthouse have been removed, and the lighthouse has been opened up for tours now. Besides that the camp sites and general feel of the island is the same.
The only way to get to this island is by boat, there are no houses (besides the lighthouse) on the island, no roads, no cars, and no running water.
This island has quite a history, much of that is covered in a book called The Light On The Island which is an great read if you are visiting the island. The book was written in the 1950's by the daughter of the lighthouse keeper who lived there from 1905 to 1930.
The harbor between Patos island and Little Patos can be a challenge to anchor in (I haven't had a problem but I have seen others have trouble). There are 2 buoys that you can pay a fee to tie up to, or you can drop your own anchor. As the tide comes and goes, the current can get quite strong closer to beach area by the campsites. On more than one occasion I have seen someone anchor close to the beach with a rope running to shore tied to a tree or log. Not such a good idea because people who do that usually end up with their boat on the beach when the tide goes out.
The harbor is very shallow at low tide, 4 to 5 feet deep in many areas, but as you get out towards the anchoring buoys it gets deeper.
From the campground you can see a variety of wildlife, some amazing eagles, or annoying wasps and yellow jackets. One night while camping we awoke to Orcas splashing in the water right next to the campsite. You may occasionally spot a river otter in the bay, or porpoise off shore.
Be sure to take the short walk to the lighthouse, it can be amazing at sunset. As you approach the lighthouse in the large grassy field, you may notice some cement footings from old buildings, the ones right near the cement Patos Island sign are the footings from the original lighthouse keepers house which burnt down years ago. Any cement footings at the edge of the grassy field by the trees are of the old military barracks that where on the island.
Scuba diving is amazing along the south side of the island, with amazing sea life to be seen. Beware of the currents, it can get a bit strong, but if you are up for a drift dive with a live boat, it can be an amazing ride.
Keep in mind that there is no running water on the island so you need to bring fresh water with you. The closest place to refill if you need more water is on Sucia island. read more
