I just did this hike 2 weeks ago for my first time...I really enjoyed it! the views during the hike aren't the most exciting until you reach the meadow and then the lake, but it is worth it in my opinion. Beautiful lake with nice waterfalls. We saw tons of scat on the trail - probably the most I have ever seen on a hike. We did not see any grizzlies but we saw two black bears. One was fairly close to the trail wandering in the bushes and the other was walking around on the other side of the lake - kind of fun to watch! The flowers were beautiful! Really nice area with less people. We didn't see anyone on our way up except trail crew.
Here's a few photos:
