Sullivan Lake is a beautiful area located about a half hour drive south west of the main Calabogie boulder area. In addition to the great climbing, it has amazing camping right on the lake, with great swimming access and a communal canoe and rowboat. It is well worth it to hike in a tent and supplies to spend a weekend camping.
It has around 70 established problems and features some of the largest boulders you will ever see. Large enough that there are also a handful of sport and trad routes.
