My husband and I are planning our first trip to Isle Royal in June 2020. We are looking to go for a few days (4-5) in late June. We decided to splurge and we are going to take the seaplane in from Houghton, MI. We are going to be the first flight out on a Thursday. I do know that there is a possibility for delays, and we are ready to deal with that.

I've been trying very hard to work out a plan for the actual hikes we are taking. We want to hike end to end on the Greenstone Trail. I would love some insight on some potential versions of our itinerary ideas. I've attached four different plans below in a pdf. The first two are very similar, with only one difference in campsites. The other two both the pipe dream (if my husband can get off of work that many days) and what I have affectionally told my husband would be a "death march." I have the benefit of being a teacher, so days off isn't an issue for me in the summer.
It might also be helpful to explain our physical conditions. First, we regularly are hiking each summer at various national parks. We regularly hike between 10 & 14 miles per day when on our trips for 5-7 days in a row. When we are in the national parks, we typically are having large elevation gains (between 1,500 & 3,500 feet of gain). We have not done any backpacking, however. I realize this is going to be very new, but we are in good physical condition, young (29 & 33) and we are used to hiking decent amount of miles with some good elevation gain. I plan on keeping my backpack at no more than 25 pounds.
I'd love to know if these plans sound like they will be okay. I also want to know if any of the campgrounds I've chosen would be a bad choice. I have heard that Hatchet Lake has quite a difference in elevation to get to the camp, but I can't figure out how to avoid it. Any advice would be greatly appreciated!
