There are very few public restrooms anywhere in the Ocean Shores community. Even Damon Point State Park has only a single portable toilet at its entrance, and even that disappears from time to time. The restroom nearest that point is owned by the Quinault Nation and is reserved for the users of their campground only.
Just west of the big entrance gate to Ocean Shores is a small facility with a big sign out front for Oyhut State Park. This is the best public restroom anywhere close to Ocean Shores, so it is best to use this restroom facility before entering the community.
While it is true that you are required to have a Discover Pass before visiting a state park, the fact is that for the most part there is also a 15 minute with no parking fee required in state parks. Thus, even if you don't have a state parks permit you can use the restroom here.
Along with the restroom, there is also a sign post with some local information, and a few scattered picnic tables.
How to Get Here: As you head south on State Route 115, the road makes a sharp 90 degree turn to the right and passes North Beach High School. To access the city of Ocean Shores, you turn left at the next major intersection and go through the big stone gateway. DON'T DO THIS! Instead, go straight past the big stone gateway to the city of Ocean Shores, and nearly immediately on your left you will see the sign in the main photo, above, indicating the presence of a small parcel of state parks owned land, which is where the restroom facility is located.
Take your time driving at night. Towards the north end of the beach the canal is extremely deep, so do not attempt to drive through. Drive along the compact sand and be careful not to get stuck in soft sand. Towing companies earn a profitable living here towing cars out, but I know for a fact there are cars buried in the sand that have never been recovered, so take heed.
For the most parts locals do not swim in the ocean, just to let you know. It may look inviting but can be very deadly even on a mild day. The Washington Coast is known for its dangerous Rip Currents. (Note: if caught in a rip-tide, swim parallel to the beach and out of the rip-tide, do not try to fight against the current its a losing battle.) For a safer alternative try the swimming pool at the hotel or motel you are staying with. Storm watching is at its best in winter and near the North Jetty. Try to get a warm and cozy rental with a view. Please be careful during these powerful storms and while in the North Jetty area. This is a time to enjoy visually from a safe distance. 25 foot seas and high winds can be extremely dangerous and will occasional crash over the protection of the jetty wall.
Don't drive on the beach at Ocean Shores with a Grand Am. (AAA does NOT cover off road tows, even though it's a state highway!)
