Belvedere Lagoon is an artificial lagoon on San Francisco Bay in Belvedere in Marin County, California. Narrow strips of land separate it from Richardson Bay (to the northwest) and Raccoon Strait. The lagoon is owned and maintained by the Belvedere Lagoon Property Owners' Association. The lagoon is not accessible by boat from San Francisco Bay, and no public access is provided. Until somewhat late in the 20th century houseboats were present in Belvedere Lagoon.There used to be a natural passage between the lagoon and the San Francisco Bay through the southern spit. The passage was spanned by a drawbridge. From the late 19th century, the drawbridge would be raised twice a year, once in the spring to allow pleasure boats of the Corinthian Yacht Club to exit the lagoon, where the boats wintered, and go to their summer moorings, and once in the fall, to allow the boats to return. This raising of the drawbridge signaled the beginning of the pleasure boat season. In 1917, that informal celebration morphed into a more formal and elaborate parade of boats that has now evolved into the Opening Day on the Bay involving the 104 clubs of the Pacific Inter-Club Yacht Association.Belvedere Lagoon was partially filled after World War II to provide building sites for tract houses and to improve access to Belvedere Island. It was also once the site of a 9-hole golf course.

The Tiburon Peninsula is a landform of the San Francisco Bay Area's Marin County and is home to the incorporated municipalities of Tiburon, Belvedere, and a portion of Corte Madera, California. Much of the peninsula is unincorporated, including portions of the north side and the communities of Paradise Cay and Strawberry. Richardson Bay separates the peninsula from the Marin County mainland. Angel Island lies app. 1 mile south of the peninsula's southern tip. Much of the land area of the Tiburon Peninsula was part of a Spanish land grant originally given to the early Californian John Reed. A prominent feature of the Tiburon Peninsula is Ring Mountain, Marin County, which forms the backbone of the peninsula and is the highest elevation of the peninsula. The Tiburon Peninsula is the location of a number of rare and endangered flora species, and is also the site of ancient Native American rock carvings. The mineral lawsonite was first described from an occurrence on the Tiburon Peninsula.

The Belvedere Tiburon Library is an independent public library serving the communities of Belvedere, Tiburon, and Strawberry, in California and it is operated by The Belvedere Tiburon Library Agency. It has as its mission the provision of library services now and in the future that will encourage and support a literate, enlightened and cultured community.The Tiburon Peninsula has had a library presence since 1895. Belvedere Tiburon joined as a branch of Marin County Free Libraries in 1929. The library ceased to be a branch in 1997, when it moved to its current location. The brand new 10,200 sq. ft. library building was built next to the new town hall to complete a civic center at the end of the peninsula. The library is a member of the Marin Automated Resources and Information Network (MARINet), a consortium of publicly funded libraries in Marin County. Deborah Mazzolini was the director of the Belvedere Tiburon Library from 1997 to 2022. She is succeeded by Crystal Duran. The architectural style is that of the 19th-century railroad yard in Tiburon, a nod to local history.

Belvedere Island (formerly, El Potrero de la Punta del Tiburon, Kashow's Island, Peninsula Island, Promontory Island, and Still Island) is a rocky island in the San Francisco Bay in Marin County, California which was formerly separated by a marsh from the mainland, though has since been linked by two spits.

Richardson Bay (originally Richardson's Bay) is a shallow, ecologically rich arm of San Francisco Bay, managed under a Joint Powers Agency of four northern California cities. The 911-acre (369 ha) Richardson Bay Sanctuary was acquired in the early 1960s by the National Audubon Society. The bay was named for William A. Richardson, early 19th century sea captain and builder in San Francisco. It contains both Strawberry Spit and Aramburu Island. In spite of its urbanized periphery, Richardson Bay supports extensive eelgrass areas and sizable undisturbed intertidal habitats. It is a feeding and resting area for a panoply of estuarine and pelagic birds, while its associated marshes and littoral zones support a variety of animal and plant life. Richardson Bay has been designated as an Important Bird Area (IBA), based upon its large number of annual bird visitors and residents, its sightings of California clapper rail and its strategic location on the Pacific Flyway. The bay's waters are subject to a "no discharge" rule to protect the elaborate and fragile ecosystems present, including a complex fishery, diverse mollusk populations and even marine mammals such as the harbor seal. Owing to its lack of depth and complicated channel structure, Richardson Bay is limited in boating uses to kayaking and small sailing craft. There are extensive hiking and bicycling paths at the bay perimeter, especially in the shore areas of Mill Valley and the town of Tiburon.

El Campo (later renamed Paradise Beach) was a picnic resort established in 1891 by the San Francisco and North Pacific Railroad in hopes of increasing ridership on their ferries between San Francisco and Marin. Facilities at the resort included a dance pavilion, merry-go-round, bowling alley, fishing pier, shooting gallery and over 100 acres of picnic grounds. The resort became such a popular attraction that crowds lined up on the pier in San Francisco on the weekend to catch the ferry to the resort. Because the site was only accessible by ferry, a local newspaper wrote that families could enjoy "absolute freedom from the incursions of hoodlums."The name, El Campo, is derived from a Spanish phrase meaning "the flat country". The site was located on the San Francisco Bay, 3 miles (4.8 km) south-southeast of Point San Quentin.

Tiburon (; Spanish: Tiburón, [tiβuˈɾon]) is an incorporated town in Marin County, California. It is located on the Tiburon Peninsula, which reaches south into the San Francisco Bay. It shares a ZIP code (94920) with the smaller incorporated city of Belvedere (formerly a separate island), which occupies the southwest part of the peninsula and is contiguous with Tiburon. Tiburon is bordered by Corte Madera to the north and Mill Valley to the west, but is otherwise mostly surrounded by the bay. Besides Belvedere and Tiburon, much of the peninsula is unincorporated, including portions of the north side and the communities of Strawberry and Paradise Cay. The population of Tiburon was 9,146 at the 2020 census and has 6,600 registered voters. Belvedere and Tiburon share a post office, library and recreation agency.The city's name derives from the Spanish word tiburón, which means "shark". The name was first given to the peninsula on which the city is situated, and probably inspired by the prevalence of locally native leopard sharks in the surrounding waters. Tiburon was formerly the southern terminus of the San Francisco and North Pacific Railroad (subsequently the Northwestern Pacific Railroad), which transported freight for transfer to barges for shipping to cities around San Francisco Bay. It is now a commuter and tourist town, linked by fast ferry services to San Francisco and with a concentration of restaurants and clothes shops. It is the nearest mainland point to Angel Island and a regular ferry service connects to the island.
