Seaside is one of the most popular beach towns in the northern stretch of the Oregon Coast, offering shops, restaurants, and RV camping optionsâall less than a 2-hour drive from Portland. It's just north of another Oregon Coast favoriteâCannon Beachâbest known for its iconic basalt rock formation, Haystack Rock. Seaside is just north of the popular hiking in Ecola State Park, and it sits just 15 miles west of the inland Saddle Mountain, which offers excellent coastal views on clear days. RV camping options in Seaside range from urban RV parks to privately owned RV campsites in the surrounding forests, many with dump stations, 50-amp hookups, or free wifi. Campers can find additional RV camping in many of Oregon's coastal state parks, including Nehalem Bay State Park and Cape Lookout State Park to the south of town, and Fort Stevens State Park to the north.
