Yes that's the trail I'm talking about. Did you guys complete the loop or just backtrack to the trailhead on day 3? If I'm doing a 2 nighter on this trail I like to spend night 1 at Maple Leaf lake like you did, but then on day 2 I use the GPS to bushwack across the loop and I camp with about 4km left to the trailhead and then it's an easy day 3. Bushwalking is fun and there are some cool meadows, streams etc that you encounter...it's always an adventure.
Original poster, not all of the trail is shown on Steve's map....there are a bunch of Y's that enable you to choose loops ranging from about 25kms up to about 90kms if I recall correctly. The further in you get, the better it gets.
