After backpacking into Many Glacier, we took a sidetrip to hit these two amazingly beautiful lakes. We first took the trail to Ptarmigan tunnel and once you get above the tress, the views down canyon, of the pass, and the lake are rather breathtaking. We took the trail up to and thru the tunnel while wondering why they didn't just build the trail over the pass until we popped out the other side which quickly drops off with the trail blasted into the side and soon realized why they did what they did. Again the views down this other canyon are quite amazing and we took the trail at least another half mile away from the tunnel to get a better view up that Belly River canyon and Ahern Glacier up above. We turned around and hike back thru the tunnel and down to the juction, but this time we took the comparatively mellow hike up to that equally beautiful Iceberg Lake. We saw a large bull moose on the way up and this easier hike also meant it's quite popular. Some crazy people like my buddy went swimming in the frigid lake, but soaking my feet was cold enough for me. After grabbing some lunch and soaking in the amazing views, we turned around and hike back to the campground...
