Sand Hollow Westside Ramp (Main) is the primary boat launch at Sand Hollow State Park, currently operating at open status with floating docks available.

The ramp is located on the northwest side of the reservoir and is the closest campground access point, making it convenient for launching boats to access the 1,322-acre reservoir for boating, paddleboarding, and diving.

All watercraft are subject to mandatory inspection and decontamination to protect against aquatic invasive species, with decontamination services available daily (7 AM-7 PM April-October, 7 AM-5 PM November-March).
