Rio Del Mar is a coastal community whose name originated in the 1920s as part of an early real estate marketing effort during the Roaring Twenties. While Rio Del Mar is technically part of Aptos, many locals view it as a distinct neighborhood, separated by Highway 1 and defined by its beachfront setting. The area experiences increased activity during the warmer months as visitors are drawn to the coastline, while year-round residents enjoy a quieter beach town lifestyle outside of peak seasons.

Housing in Rio Del Mar reflects its proximity to the ocean. Many properties closer to the beach include multi-story townhomes well-suited to coastal living, while inland and Seascape adjacent areas feature a mix of custom and higher-end single-family residences. This blend of housing types contributes to Rio Del Mar’s role as both a residential neighborhood and a destination community.

Just south of Rio Del Mar State Beach sits Seascape Beach Resort, a coastal resort offering ocean-facing accommodations and access to walking paths along the bluffs. Nearby, Seascape Golf Club occupies the coastal highlands above Monterey Bay and provides a scenic golf experience with rolling terrain and ocean views.

The Rio Del Mar and Seascape areas are served by the Pajaro Valley Unified School District, with local elementary, middle, and high school options serving the broader Aptos region.

Rio Del Mar falls within the 95003 zip code, shared with Aptos. Housing throughout the area is primarily single-family, with a notable presence of condominiums and townhomes, particularly in locations closer to the beach and resort areas.
