did this with string lake for a great morning hike last week - start early. part of trail was closed due to rockfall so did not see hidden falls but scenary made up for it! was a zoo by the time we left at 1pm but had time for a quick dip of the feet in the lake (great after 18km) before getting out of the chaos! long but very easy - nothing technical and no major climbs so just a really nice morning hike.
