The pier it a terrific place to start your tour of Oceanside. Take a walk out to the end and watch the surfers. Then take a walk on the strand or just cruise in your car along the edge of the sand. The beach is awesome too. If you want fine dining check out 333 Pacific at the foot of the pier. If you want a casual experience with the locals and tourists alike go two blocks inland and go to the Cabo Grill. The rooftop at the Cabo Grill is one of the best places on the planet to sit back and enjoy the sunset with cocktails and Mexican food.
