Whether you’re looking for a break from the beach, planning a family outing, or simply searching for a fun activity on a cooler day, The Plunge San Diego offers a one-of-a-kind experience in the heart of Mission Beach. Located inside FIT Mission Beach at Belmont Park, this historic indoor pool combines nearly a century of history with modern amenities, making it one of the area’s most unique attractions. Originally built in 1925, The Plunge has been transformed into a year-round destination where visitors of all ages can swim, play, exercise, and relax.

WHAT IS THE PLUNGE SAN DIEGO?

The Plunge is a historic indoor swimming pool located inside FIT Mission Beach at Belmont Park. When it first opened in 1925, it was the world’s largest saltwater swimming pool, holding approximately 355,000 gallons of water. Today, after a major renovation, it remains one of Southern California’s largest heated indoor pools while preserving many of its original architectural features.

One of its most recognizable features is its floor-to-ceiling windows and retractable roof, allowing guests to enjoy beautiful Mission Beach views while swimming in a climate-controlled environment throughout the year. The pool is heated to approximately 83–85°F, making it comfortable during every season.

WHY VISIT THE PLUNGE?

The Plunge offers much more than a traditional swimming pool, making it an excellent activity for families, couples, and visitors staying in Mission Beach.

One of its biggest attractions is the giant inflatable obstacle course, where guests can climb, jump, balance, and race across floating obstacles. It’s a favorite for kids, teens, and adults looking to add a little adventure to their day.

Visitors can also enjoy:

  • A heated indoor pool open year-round
  • Seven 25-yard lap lanes for recreational and fitness swimming
  • A dry sauna for guests ages 16 and older
  • Functional fitness equipment on the pool deck
  • Ocean views through floor-to-ceiling glass walls
  • Family-friendly swim sessions and aquatic programs
  • Locker rooms, showers, and keyless lockers for added convenience

Because it’s located inside Belmont Park, The Plunge also pairs perfectly with a full day of exploring the amusement park, restaurants, shops, and the Mission Beach boardwalk.

ADMISSION OPTIONS & PASSES

One of the best things about The Plunge is that you do not need a membership to visit. Guests can purchase short-term or day passes, making it an easy addition to any Mission Beach itinerary.
