Two-Tiered Aid Wall
For sure on the bucket to-do list, the two aid routes on the slab high above are Freedom Roof(A1) and Hidden Link Roof (A2/3). They look like a load of fun and the view from the arches here is wonderful – if it rains this is an ok place to get some shelter.
Hidden Valley is the place you wanna go, so drive north from Jasper 35km and park on the right in the lot. Hike up around the left side of the pond on a trail that climbs, passing a small ladder at one point even.
You will pass many fun walls, but if the arches are your goal, expect 40 minutes of hiking time, especially on a hot summer day.
