Trip details

Access rules, camping and seasonal notes.

Permits, camping and season
PermitsNone notedNo route-specific paddling permit is known. Use the Highway A bridge access only where parking is legal, follow Marathon County park rules at Rib Falls, and respect private banks.
CampingDay tripNo on-route river camping is assumed. Rib Falls Park is a developed county park for day use; confirm any separate nearby camping before relying on it.
SeasonApr-OctThe route has a narrow broad-audience floor: Miles Paddled found 298 cfs comfortable but close to the minimum. WRT supports 201-300 cfs as the general target but this card keeps the higher Miles floor for fewer scrapes near island narrows.

Access and shuttle

Launch at County Highway A and take out at Rib Falls County Park above Big Rib Falls. This is a scenic riffle-and-outcrop connector, not a falls-running recommendation.

DirectionsOpen map

Miles Paddled gives GPS points for both endpoints and describes the Highway A launch as a small trail from the road.

Finish

Take-out

Rib Falls County Park take-out above Big Rib Falls
DirectionsOpen map

The take-out above the falls may be steep or awkward; identify the gradual option and do not drift toward the brink tired or distracted.

Road shuttle

Scout the Rib Falls County Park take-out before launching, then stage Highway A. The route must end above Big Rib Falls, and high water can make the last approach less forgiving.

Additional access notes
  • Rib Falls County Park is a Marathon County park with trails, picnic amenities, and vault restrooms, but fishing is prohibited and posted rules should be checked.
More route and safety guidance
  • Island narrows and riffles scrape near the selected floor and can hide wood or shallow slots after storms.
  • The County A bridge put-in has limited parking, and the park take-out requires carrying through uneven falls terrain.

  • Threshold support298 cfs minimum; 201-300 cfs WRT target

    Miles Paddled says 298 cfs was very good but near the practical minimum; WRT gives 201-300 cfs as a good target and 501+ cfs as very high.
