Theodore Roosevelt Island sits in the Potomac River near the Key Bridge. While the only way to reach the island by land is from the Virginia side of the river, the island is actually part of Washington, DC.
Please note that you must park in a designated parking space. US Park Police regularly tickets drivers who have parked on the grass.
On Foot or by Bicycle
Bicycles are not allowed on the island. Bicycle racks are located near the footbridge.
