Yes, you may drive on the beach. There are times and places you cannot, however.
Taken from
www.funbeach.com/activities/beachdriving:
The Peninsula shoreline is a Washington State Highway. All drivers and vehicles must be licensed and insured just as on any other State Highway (Sorry, no ATVs). The speed limit is 25 mph, with extra caution to be taken for other vehicles, pedestrians, sunbathers, and beach debris. The beach is patrolled frequently and all laws are strictly enforced. Reckless or careless driving is not tolerated and can result in expensive tickets and even license suspension, so please, play it safe! Parking is allowed.
The beach is always open and free to pedestrians, equestrians and bicyclists. Sections of the beach are open to automobiles year round while others are closed April 15 through the day after Labor Day (some closed sections are open during recreational razor clam season). The beach closures protect the delicate nesting grounds of migratory birds as well as give families a place to play on the beach without concern for vehicle traffic.
I hope that helps. I was going to put that in my own words, but that is simply more of an elegant way of doing it......
I live about 3/4 of a mile from the Klipsan Beach approach and take the beach all the way to town when I can. I don't advise driving the beach unless you are driving a 4 wheel drive vehicle or are very skilled in avoiding getting stuck. Tows aren't cheap and only one or two companies tow people off the beach.
I highly recommend a visit. Long Beach itself is very tourist oriented with lots of shops and restaurants.
I live out in Ocean Park, which is about 10 miles north of Long Beach. The farther you go north from Long Beach, the more homes you will run into. If you are looking to relocate, now would be the time. Lots of houses on the market!
Just in case no-one has heard of Long Beach, WA here is where we are:
We are located 30 miles North of Astoria Ore on the SW Washington Coastline. To go to Long Beach From Astoria, Or take the Astoria/Megler Bridge north to Washington, when get to the end of the Bridge, turn Left and follow road into Chinook, WA. Go through Chinook and continue North until you see the KOA Campground, from there, Turn Right and follow the road the end, then turn left and continue into Long Beach.
To go into Ilwaco, instead of turning at the KOA, keep going straight and follow the curves into Ilwaco. At the light in Ilwaco you can Left to the Port of Ilwaco, or Right and follow US 101 into Seaview and Long Beach.
To continue to the North end of the Peninsula, take either Sandridge Road or the main highway north.
