Bon Echo Hut - Toronto Section

Adventure Climbing at Mazinaw Lake

Update: please see the ACC Toronto Section's Bon Echo website for more information, including Covid-19 protocols and updates.

The rock climbing at Mazinaw Lake is some of the finest in Ontario. The area boasts quartzite cliffs up to 100m high that rise vertically out of the lake. The routes are all traditional and range in grades from 5.0 to 5.11, with the most popular routes in the 5.4 to 5.9 range. The exposure and length of the routes make for an adventure unlike any other in the province.

The Bon Echo Hut on the lake is operated by the Toronto Section which also operates a boat to ferry climbers to and from the climbs. The hut is comfortable and an excellent place to meet other climbers and get information on the climbs. The area also offers excellent swimming and hiking.

The hut is a single-room wooden structure with a fireplace and kitchen equipped with propane stoves and a large dining table. There is a sauna located near the lake. The hut is not used for sleeping, but is a day hut and cook shelter for those staying at the campsites immediately adjacent to the hut.

Bon Echo is located approximately 300 km north east of Toronto on the east side of Mazinaw Lake, a mile north of the Mazinaw Rock and Bon Echo Provincial Park.

The drive to the public dock takes three to four hours from Toronto or one and a half hours from Ottawa. The hut can be reached by hiking overland, but this would take an entire day. Boating to the hut is much more convenient.

More info on the Bon Echo Hut on the Toronto Section website. Details on the hut custodian weekends can be found on the Toronto Section’s calendar page.
