Kayak the Fox

South of Waukesha the Fox River flows travels through extensive natural areas including many wooded areas and the Vernon State Wildlife Area, aka Vernon Marsh. Paddling on the river will give us a unique perspective from which to observe birds that, for one reason or another, seem to ignore people in paddle boats.

We will start the paddle from the Fox River Park on Hwy H. The first take out option is at Cty I after about 5 miles; this stretch takes about 2 hours to complete. Intrepid paddlers may continue on through the Vernon Marsh and take out at Cty ES (National Ave) which is about another five miles; this leg will take another 2 to 3 hours. Kayaks and canoes are welcome, but we unfortunately do not have extras available. If you would like to participate in the paddle, contact Tim Hahn (
