Isaac showed me the Opax Mountain hiking trail today leaving from the north side of Lac du Bois (the lake, not the grasslands protected area). The trail moves of level open ground for the first 30 minutes or so and then turns up the mountain into the forest. It climbs steadily up but the grade is very nice for walking as it follows an old road. It was a fantastic time in the outdoors. We hiked from roughly 9:00am-2:00pm stopping wherever there was something to see. In the end we reached approx. 300-400 m past the top cattle guard where it levels out at the top.
