Mission Beach spans nearly two miles of ocean, with a boardwalk on both the ocean and bay side, between Mission Bay to the east and Pacific Beach to the north. The boardwalk has been expanded and separated by a yellow line for foot traffic on one side and wheels (roller blades, bicycles and skateboards) on the other. At the south end of the beach a jetty, with grass, parking and a walk, extends into the ocean.

Mission Beach offers opportunities to participate in sunbathing, horseshoes, surfing, bicycling, skateboarding, Frisbee tossing, and other outdoor activities. A local skating club, "Skate This!," performs for free on weekends, executing trick skating and dancing on both rollerblades and traditional skates. It has become well known as a popular place to engage in sports, including beach volleyball[3] and basketball, with courts available for both.

Mission Beach includes Mariner's Point, the original site of the Over-the-line softball-on-the-beach tournament.

Thong bikinis are technically illegal on Mission Beach, but lifeguards and local police do not usually enforce the ban on such swimwear. The consumption of alcoholic beverages on the beach is illegal as of April 2008. Nudity is not allowed.

Many of the beachgoers are local college and university students, but both tourists and permanent residents of the beach and other areas are also frequent visitors to the beach. Weekly and monthly rentals are available during the summer months. Nearby Pacific Beach is to the north of Mission Beach.
