Located just 45 minutes from Toronto, Mount Nemo is the premier crag in the Milton region. The over-2km long cliff has more than 350 routes ranging from easy 5.fun trad adventures to challenging 5.12 sport classics.

The crag's northern aspect ensures cool conditions making this an ideal climbing area during warmer weather.
