Long trip 26 km 1750 m gain – 12 hours RT – I cramped up at 2800 m and called it a day.
Hidden lake was very low so easy to walk along shoreline trail. Cairn and blue ribbon to head back into forest to catch the great trail which switchbacks up the headwall. much better than old trail which now is not maintained and has deadfall over it. Turn left up slabby ribs near highpoint on trail to catch Sarrail ridge. Above treeline on grass go left (cairns) on trail around a cliff to avoid steep loose scree band. follow ridge to summit.
