MainStreet Oceanside

MainStreet Oceanside had its beginnings as the Downtown Business Association. Formed in the early 1990s as a loosely organized group of business people who met on a regular basis to discuss common concerns. Now as a certified California Main Street city with official status granted in July 2000, MainStreet Oceanside is a thriving community with plenty of Things To Do!


Much of life in downtown Oceanside centers around 3.5 miles of beaches. With such beautiful beaches and ocean vistas, who wouldn’t want to spend as much time as possible at the edge of the blue Pacific?

Oceanside’s Pier

Stretching out at about 1954 feet, Oceanside’s pier is the longest wooden over-water pier on the west coast of the United States. Walk the length of the pier for some truly awe-inspiring views of the downtown coastline and reward yourself with a meal or a treat from Ruby’s Diner located at the end of the pier.

Oceanside Harbor

Oceanside Harbor is a little bit of paradise. With 950 pleasure boat slips, quaint village shopping at resort-style boutiques, and top-name restaurants the Harbor is fun for everyone. There are plenty of things to do, whale watching, people watching, picnicking in mini-parks overlooking the harbor, and strolling or jogging around this idyllic setting.

Arts & Culture

Visit the Oceanside Museum of Art for a diverse range of engaging exhibitions and programs that connect people with regional, as well as national and global artists.
