Torrance Barrens is a conservation reserve of about 1,990 hectares off Southwood Road near Gravenhurst, and it is described as the world's first permanent dark-sky reserve, designated in 1999. By day it is a strange and beautiful landscape of low Precambrian bedrock ridges, wetlands and peat-filled hollows, with scattered pines and very little shade, which gives it an almost lunar look. By night it is one of the darkest places within easy reach of the Toronto region, which is why astronomers and casual stargazers come here for the Milky Way, planets and meteor showers. Three marked trails are open for hiking and mountain biking, and six designated campsites are offered on a first-come, first-served basis. It costs very little to visit, and it is a good example of the quieter, wilder side of Muskoka that has nothing to do with resorts or cruises.
What to expect
A walk over smooth granite with long views, small lakes and boggy hollows, and a sense of openness that contrasts with the dense forest elsewhere in Muskoka. The trails are short enough for an afternoon, and the rock can be slippery when wet, so wear shoes with grip. In late summer the blueberries ripen on the ridges, and the wetlands attract birds and dragonflies. At night, the lack of nearby lighting means the sky opens up once your eyes have adjusted, a process that takes about twenty minutes.
Stargazing tips
Go on a clear night around the new moon, when the sky is darkest, and arrive before sunset so you can find your way and set up in daylight. Use a red torch rather than white light, because red keeps your night vision, and switch off headlights as soon as it is safe. Bring warm layers even in summer, since the open rock loses heat quickly, together with a chair or blanket, a thermos and insect repellent in the warm months.
Respect other visitors by keeping lights, music and voices low. A star chart or phone app in night mode helps with constellations, and a pair of binoculars shows more than most people expect.
Practical points
The reserve is a conservation area rather than a developed park, so do not expect shops, a visitor centre or guaranteed facilities, and take out everything you bring in. The tourism board page links to the reserve's own information and to the township trails page, which are the best places to check access, camping arrangements and any seasonal notices before you travel.
Cell signal can be weak, so download directions in advance. The reserve combines well with a day in Gravenhurst, and a clear night here is a rewarding ending to a day that includes the Discovery Centre or a lake walk. If you plan to camp, arrive early, because the six sites are first come, first served.
Seasons
Summer evenings bring the Milky Way and the warmest conditions, while autumn gives cooler, clearer air and fewer insects, and winter can be spectacular on a still night if you are dressed for it. Cloud is the main enemy, so check a forecast the same afternoon and have a backup plan in Gravenhurst. Photographers should bring a tripod, a wide lens and a remote release, and should try a long exposure of the granite ridges against the stars.
What to expect
The experience
A self-guided walk or ride on three marked trails over granite barrens, with an optional night of stargazing or camping.
