Sherman Island is located at the confluence of the Sacramento and San Joaquin Rivers, two of California's largest waterways.
The island is situated significantly below sea level, making it a critical area for regional levee maintenance and flood control infrastructure.
The area is renowned among kiteboarders for 'The Sherman Blow,' a consistent afternoon thermal wind effect caused by the interaction of coastal air and the inland valley heat.
It contains portions of the Great California Delta Trail, a planned multi-use recreational trail system.
Sherman Island is a primary destination for windsurfing and kiteboarding in the Sacramento-San Joaquin River Delta due to its consistent thermal winds. The park is managed by Sacramento County Regional Parks and features access to the Sacramento and San Joaquin rivers. Much of the island sits below sea level, protected by a complex system of levees maintained by the local reclamation district. The park area, specifically the Sherman Island Public Access Area, provides primitive launch points for small watercraft and fishing access. Vegetation consists primarily of tule marshes and riparian grasses consistent with a delta ecosystem. It serves as an important junction point where the two major river systems converge. Visitors often use the site as a base for exploring the surrounding waterways and sloughs.

Check wind forecasts specifically for the Sherman Island site before arrival, as conditions change rapidly.
Bring plenty of drinking water and shade equipment, as the island is exposed with minimal natural cover.
Ensure your vehicle is capable of navigating gravel or dirt levee roads, as surface conditions vary.

Practice 'Leave No Trace' principles by removing all trash, as there are no waste disposal services on-site.
