Mason Valley WMA Access provides entry to a wildlife management area north of Yerington featuring multiple ponds and water bodies along the Walker River, with improved boat ramps at North Pond (paved parking and campsites available) and gravel/padded ramps at Bass Pond and Hinkson Slough.

Well-maintained dirt roads throughout the area facilitate access to different water areas, though visitors should verify water depth before launching as conditions may be shallower than expected.

Camping is permitted at designated sites, and the area offers amenities including parking and toilet facilities.
