In September, 1983 Peter Croft traversed around Garibaldi Lake in 21 hours climbing Castle Towers, the North Ridge of The Sphinx (5.9) and likely Mt. Price. It sounds like he even stopped in at the Ranger Cabin for dinner before heading down the trail at the end of the day. Tami Knight's recollections of his day can be found here: http://www.supertopo.com/climbing/thread.php?topic_id=668163&tn=258
Not being Peter Croft, Eric and I avoided the North Ridge of the Spinx in favour of its easy Southwest Ridge. We did climb Mt. Carr which seems like a logical addition to the route. We were moving steadily, but our time leaves a fair bit of room for improvement for future parties.
A lower route around the lake is possible by dropping from Gentian Pass to Sphinx Bay, and then climbing over Deception Pass into Sentinel Bay. This route avoids any significant glacier travel and is somewhat more commonly attempted, although is still very much a wilderness experience. Circumnavigating the lake by either route is spectacular and highly recommended.
