Oceanside is a lovely place along the Oregon Coast to check out, a little bit sleepy compared to the more touristy cities on the beach, but I believe that adds to the appeal. It's a nice place to explore and walk around. If you're into activities like rockhounding, it's also worth checking out. The tunnel is really cool and definitely something to check out when in the area, fun to explore and walk around.
Stayed in the Cabins right off the beach. The cabins got the job done, but between this beach and being connected to Tunnel Beach, it made the trip to the coast while visiting OR well worth it! I was able to see the tide get high the night we stayed because it was storming a little - which, to me, added beauty. Then, in the morning when we woke up early and got to see low tide, it was so low we were able to walk out to some of the rocks and see starfish as well as a few other sea creatures.
