We will be on a 9 day tour of Banff, Yoho, and Jasper National Parks filled with lots of hiking starting the first week of September. Since it is just my husband and myself, we are concerned about the restriction of groups of 4, especially at the Valley of Ten Peaks area and the Larch Valley/Sentinel Pass trail as this hike is high on our list. How hard is it to meet up with other hikers? Should we play it safe and reserve a guided hike with Great Divide Hikes? I've heard it is possible to wait at the trailhead or make arrangements at the Information Centre to meet up with other hikers? Any advice?
