From TOT sight:
2018 Trail Meals are sold out. We anticipate 2019 meals being available in September 2019.
But you can go online and view previous menus for all 10 breakfasts, lunches and suppers so you can make-up you own trail meals from Mountain House and Backpacker’s Pantry prepared meals and super market items listed in PSR menus.
Package each meal for 2 campers in freezer-grade re-sealable plastic bags with labels stating meal name and ingredients.
“Philmont should be enjoyed, not endured.”
