The Nicomen Lake trail has 2 potential purposes, and a nice hike is not one of them. At 17+ km each way on a featureless trail I can only recommend walking this trail if you are A - really into fishing and want a guaranteed catch of many fish or B - as the exit point for the Heather Trail so that you don't have to backtrack (instead of hiking 23 back the way you came you could have left a car at Cayoose).
Were it not for the excellent conversationalists that joined my callout (Jangwon and Darren), this trail would have been even more tedious. The lake itself is nice, and the camping area on its edge,.. brilliant,.. but this is no Wedgemont, or even Garibaldi. We did hike to the ridge in the morning which was worth it, but if you were hiking the Heather trail this is how you would approach your final campsite anyways...
This was a slog as evidenced by 6 sore feet and matching legs. The trail is groomed, Garibaldi style, so at no point is it "steep", just really really long and uphill the whole way there (leaving was far more enjoyable but still long!)."
