A Muskoka conservation reserve of bare rock and wetland south of Gravenhurst, known as one of Ontario's best dark-sky spots. Great for stargazing and hiking; very crowded on big sky nights.
Torrance Barrens is a sweep of bare Canadian Shield rock, wetlands and small ponds south of Gravenhurst. It's famous for its night sky: in 1999 it became the world's first permanent dark-sky preserve, and with no nearby light pollution, visitors describe seeing the Milky Way, meteors and, on lucky nights, the northern lights.
It's worth seeing by day too. There are two main loops, a 3 km Main Trail and a 5 km Pine Ridge Loop, plus a longer Barrens Extension past a marsh where beavers are often seen. The trails are semi-wilderness and can be wet in spring. The reserve allows sport fishing and canoeing on its ponds under Ontario rules, and there are a handful of free first-come backcountry campsites.
For stargazing, go on a clear, moonless night and let your eyes adjust. Late-night visits after midnight are quieter. The open rock is easy to set up a telescope on.
The big complaint is crowds: on meteor shower or aurora nights, cars and flashlights can overwhelm the place, and one regular stargazer gave up on it for those events. Use only red lights. A local also warns that this is massasauga rattlesnake habitat, so wear proper footwear, not sandals, and watch where you step.
