Portola (/pɔːrˈtlə/ por-TOH-lə) is a small city in Plumas County, California. It is the only official city in the county. In 2020, about 2,100 people lived there. Portola is located on the Middle Fork of the Feather River. The city was named after a Spanish explorer, Gaspar de Portolá. However, he never actually explored this specific area.

Portola is an important spot for trains on the Western Pacific Railroad (now Union Pacific Railroad). This route goes over the Sierra Nevada mountains. The city is also home to the Western Pacific Railroad Museum. This museum is one of the biggest train museums in the western United States. It's famous for its "Run A Locomotive" program. This program lets people experience driving a real train on the museum grounds. The city also celebrates its train history with a yearly event called "Railroad Days."

In the late 1990s, Portola was in the news because of a problem in Lake Davis. An unwanted fish called northern pike was found in the lake. The California Department of Fish and Wildlife worked to remove these fish. In 1997, the lake was treated with chemicals to get rid of them. But the fish came back in 1999. In 2007, the department used a new liquid treatment to remove the pike again.

The city of Portola sits along both sides of the Middle Fork of the Feather River. It is in the eastern part of Northern California's Plumas County. Portola is on the eastern slopes of the Sierra Nevada mountains. The area is part of the Feather River drainage system. This system flows westward down the Feather River Canyon.
