Beachside Fun with Modern Flair. Located 83 miles south of Los Angeles and 35 miles north of San Diego, Wyndham Oceanside Pier Resort is situated right at the base of Southern California’s longest active recreational pier and across from the beach. 'Active' certainly describes all the delightful choices here! Oceanside’s nostalgic feel and idyllic weather draw plenty of surfers and artists; yet this thriving community includes plenty of modern delights, too. Enhance your romantic retreat or family gathering in a place as warm and inviting as the California sun and surf itself!
