Henry Cowell Redwoods State Park has a shaded campground with potable water, restrooms, and close access to redwood trails—suitable for motorhome stays though hookups are limited. Seacliff State Beach campground provides RV-accessible sites near the beach with restrooms and nearby services for fuel and supplies. The Santa Cruz / Monterey Bay KOA is a private RV park offering pull-through sites, full hookups, laundry and Wi-Fi, which makes it a convenient option for larger motorhomes. All three locations keep you close to the outdoor attractions and scenic drives around Ben Lomond, but be sure to reserve ahead and confirm site dimensions for larger rigs.
