Ventura Marsh Access provides parking lots and primitive access to a 991-acre wildlife management area featuring half marsh and half upland habitat, popular with waterfowl hunters and birders.

The west side access (on West Lake Street, one mile west of Ventura) offers two parking areas with an unused service road leading into the marsh, while a south access is available from 240th Street, though both require walking/bushwhacking to reach interior areas.

The site is known for excellent spring and fall birding opportunities with minimal amenities—no maintained paths, lookouts, or facilities—making it suitable for experienced outdoor enthusiasts seeking primitive marsh exploration.
