We stayed at this location for 2 nights, hiking up from Echo Lake.  There are multiple established camping areas with enough space for a few tents.  Accessing the lake for water was difficult due to willows and mud.  We eventually found a stream flowing down to the lake that was easily accessible from the primary trail.  We got in around noon and had our pick of sites, but it was full by evening.  Steady foot traffic on the trail.  Very quiet at night.  No issues with wildlife.
