The park is connected to a wider network of community-integrated greenways that allow for extended walking routes through the Terra Linda valley.
Lagoon Park is a recreational space located in the Terra Linda neighborhood of San Rafael, managed by the Marin County Parks department. It features a small, man-made lagoon that serves as a focal point for the surrounding grassy areas. The site is primarily utilized for neighborhood recreation, offering open spaces for casual outdoor activity. It sits adjacent to the larger Munson Point and other natural preserve lands within the Marin County park system. The park provides paved walking paths suitable for strollers and light exercise. It is integrated into the local suburban landscape, acting as a green buffer between residential housing and nearby hillside trails.
