This was a gorgeous trail! It's well marked and except for a few mild hills it was pretty level. In most places the trail was wide and smooth enough for me to be able to enjoy the scenery instead of watching my footing.
I camped at Lake 1. The lake has a clay bottom so not really suitable for swimming but it was pretty! There are 2 vault toilets. There's a pump but no handle so I filtered water from the lake.
I did the full loop starting from Guernsey Lake but be aware that the campsites cam be reached from the Sand Lakes parking area with just a short walk. This meant that I had some partiers sharing the area even though it was Tuesday.
I would definitely rate the trail more towards the easy end.
