Groveland has always been an important stop on the highway to Yosemite but really grew in the early 1900s with the development of the Tuolumne River Hetch-Hetchy water project for the city of San Francisco. Groveland is adjacent to the Stanislaus National Forest and is known for the historic Iron Door Saloon. Groveland was originally a gold rush town and then became a sleepy farming community until the San Francisco Hetch Hetchy water project made it their headquarters and built a railroad yard and hospital for the work crews. From 1915 till 1935 Groveland was a boom town supporting seven hotels, 10,000 residents and much activity. When the work crews left the town again became a minor stop on the way to Yosemite until the Boise Cascade company built the Pine Mountain Lake community with a first class golf course, an airport and lake and staked out 5000 lots. This development has since grown from a summer home area to a retirement community to a thriving neighborhood with year-round families, boosting the once sleepy Groveland to a travel and vacation destination in its own right. Groveland is the main town on the Highway 120 route to Yosemite National Park, and boasts numerous lodging and restaurant businesses. Tioga High School and Tenaya Elementary School are located in Groveland.
