This loop took in a number of official & unofficial peaks in Castle Provincial Park. The South Castle access road was dry but a little rough in places, with some potholes big enough to swallow a car.
The trail is excellent up to Whistler Mountain and the side-trip over to Table Top Peak. From there we followed the ridge back along to Frankie Peak & Larry Mountain, where there were a few sections of moderate scrambling. We descended the ridge a bit further and then dropped through a short forest section into the bowl south-east of Mount Gladstone. From there was a straightforward stroll up to the Gladstone summit, the highpoint of the day. We headed down to the forested bump known as North Castle, where some short rock bands provided the most interesting scrambling of the day. The descent back down the ridge to the road crossed through light forest and grassy slopes, until the last kilometer which was frequently a logstacle course.
