South Lake Desour was my least favorite campsite on Isle Royale National Park. It felt suffocating with the afternoon heat and the bugs were insane. About 8:00 p.m. you had to dive into your tents to survive the mosquitos. The noise sounded like a jet engine out side the tent. Anyone without a bug net would be miserable.
Even at 7:00 a.m. in the morning when we were trying to pack up, we were bitten like crazy. Lesson learned: spray your clothes with permethrin before you go backpacking in Isle Royale. BUT it is Isle Royale national Park so it still gets three stars.
