Colsac III

Columbia County's Navy





The Colsac III ferry, which crosses the Wisconsin River between Columbia and Sauk counties, is Wisconsin's only free ferry. It shuttles traffic on Wisconsin Hwy 113 between Okee on the east bank of the river to Merrimac on the west bank. Colsac III was commissioned in 2003.

The ferry is open for service 24 hours a day, 7 days a week, normally from April 15 thru November 30.


Call (608)246-3871 to check availability.


The trip is free...the scenery superb! But the main factor in its popularity is pure nostalgia!  It is now the only ferry remaining on the state trunk highway network.

The peak of the season comes in August when up to 1,200 vehicles a day create a line up of 50 or more vehicles waiting their turn for the ferry.


Small snack stands line the road on both approaches, dispensing soft drinks and ice cream at a staggering rate.


No accurate counts exist to determine the number of tourists, but estimates are in the range of 150,000 to 200,000 -- not bad for a village with less than 300 population.


Ferry service has been provided in this area for more than a century.
