>>444000I've never been on those trails but I can give you some basic advice.
-Heavy shit on the bottom and towards the middle of your pack.
-Invest in trekking poles. Seriously. Even if it's pretty flat. Sometimes you just want to spread out the load.
-Wear synthetics. This is less important in the summer, but the cold (and hypothermia can sneak up on you) so play it safe and use synthetic base layers. You will be moving and sweating.
-A lot of people new to hiking who have camped a lot in the past take too much damn shit with them. When you're only 'hiking' 15 minutes or driving a car to your site, a 60 or 70 pound pack isn't so bad. When you're laying down 20 miles? Fuck that. I usually rock a 30 pound pack for a 3 day trip, and some might say that's too much. Cut out as much as you safely and comfortably can.
-Food and water will be most of your weight. If you can get away with only carrying a couple liters of water at any given time (if there are tons of points you could get water at) do it. 1 L of water = 1 kilogram = 2.2 pounds.
-Food wise, dehydrated food like pasta or Mountiain House meals for big meals (usually only dinners) and snacks like trail mix (aka GORP) jerky, Snickers, etc are all good. A personal and lightweight cold lunch favorite? Tortillas with pieces of sharp cheddar and pepperonis.
Any specific questions, OP?
