EntryWalk the ~50 ft from the roadside down a pebble beach and enter anywhere along the half-mile shoreline. The drop-off is immediate, so almost no surface swim is needed. For the Alley Cat sunken sailboat (~60 ft), enter southeast of the Mankato intersection; for the truck-chassis boat trailer, swim to the farthest buoy off the second dock left of Mankato, drop, head east to 110 ft, then north to the chassis.
ExitAscend the slope and exit on the beach as close to your entry as possible — staying near shore keeps you clear of the heavy boat traffic.
ParkingFree roadside parking along the wooden posts next to the Hwy 89 bike path, about 50 ft from the water, open year-round; do not block the bike path. Restrooms at the south end of the bay. Low crowds in winter, very busy in summer.
