We drove to Bear Lake Trailhead after 4 p.m. (between 9 a.m. and 4 p.m. during the week, the road is closed to car traffic...only shuttles are allowed due to road construction). The lake trail is easy to walk. In early June, there was still snow on the trail. The lake was serene and beautiful. There is a interpretive guide for $2 that is well worth the cost. It explained at various points what you were seeing. I found that very interesting...explaining about rock slides, lichen, various types of trees, names of mountain peaks, etc. We decided to take the mile hike to Nymph Lake. It was not a difficult trail, but the elevation changes left us breathless along the way. Luckily, there's plenty of boulders along the path to sit on to catch your breath. While on the trail you can hear rushing water down below and occasionally you see a glimpse of the stream. Nymph lake is small and very beautiful. Walking down from Nymph Lake was much easier than climbing up the trail. Because we're from the Midwest, we saved this trail for later in the week...thinking we were getting used to elevation. I guess it takes longer than 5 days to acclimate.
