PR 268 starts in the Municipality of Minitonas-Bowsman just east of the town of Minitonas at an intersection with PTH 10 (Northern Woods and Water Route).

It heads due north through rural farmland for several kilometers to cross the Sinclair River before having an intersection with former PR 587 (closed in 2006).

The highway now winds along the east bank of the Swan River for few kilometers before entering the Rural Municipality of Mountain.

Immediately upon entering the Rural Municipality, it crosses the Swan River as it passes through the hamlet of Lenswood, for which the highway is named.

Leaving Birch River, the highway winds through some woodlands before coming to an end at another intersection with PTH 10 (NWWR) along the edge of the Porcupine Provincial Forest.
