Tank Hill is accessed by Twin Peaks Boulevard at Crown or Belgrave off Stanyan Street in San Francisco, California. This particular area has a 20 percent grade, making the hills and streets very steep. Tank Hill is considered a Municipal Hilltop Park and SNRA Park. There are no facilities and no fee is required. Dogs are not allowed off leash as the environment is highly sensitive. It also has foxtail and poison oak foliage, which mean visitors should stay on the path that meanders through Tank Hill.
Tank Hill is notable for one reason: the view. It has a panorama view of San Francisco most particularly the Buena Vista district and Mount Sutro. There are several outcroppings to add to the visage of the hill. Tank Hill became a park in 1977 after the municipal life changed towards a local water supply. The land was owned by Spring Valley Water Company and then by the city, until it was no longer needed for water and became the park it is today. Tank Hill is a veritable forest of native plant species and flowers including Eucalyptus trees. In spring the hill is covered with several flowering blooms, adding to the beauty of it and attracting butterflies.
