Gated, camera-monitored storage in Sun Prairie with outdoor RV and boat parking and 24/7 access.
Sun Prairie, WI
Boat Storage in Sun Prairie, WI
Sun Prairie has two boat storage facilities listed, averaging 4.7 stars across 41 reviews, and one of them keeps the gate open around the clock. That is a thin market for a city this size, so the good spots fill early. Both places sit on the east side of the Madison metro, which keeps a trailer out of the driveway and off the street before the first hard freeze.

What the two facilities offer
First Choice Storage earns 4.8 stars from 24 reviews and covers outdoor and boat storage with a gated entry, cameras and climate control on site. Autumn Wood Storage sits at 4.6 stars from 17 reviews, also gated, with lighting across the grounds and boat storage as its main draw. Neither lists indoor or covered boat options, so plan on open-air storage and the UV and hail exposure that comes with it in Dane County. Only one of the two advertises 24/7 gate access. If you like to launch early or pull in after dark, confirm hours before you sign anything.
Picking a spot for a Wisconsin off-season
Outdoor storage works fine here as long as you prep the boat, not just park it. Pull the drain plug, fog the engine, and haul the battery inside for a maintainer over the cold months. A quality cover that sheds water beats a tarp that pools and mildews. Ask each facility how the ground drains after spring melt, since a low corner of gravel can turn soft by March. Compare what your insurance covers while the boat sits off your property, and read the lease for any storage requirements the facility sets. Then check the gate hours against your own schedule before committing.
Around Sun Prairie
This is a straightforward drive from Madison and the surrounding communities, with three more boat storage facilities within reach if the two local options are full. That matters in a market this small. Call ahead, ask about waitlists, and look at the grounds in person before you pay. Walk the row where your trailer would sit, check the lighting at night, and see how tight the turns are with a trailer behind you. A facility that looks fine on paper can be a headache to back into on a Saturday morning.
