Our troop is doing Sea Base next year. 2019 will be either Philmont or Northern Tier.
Our troop is fairly young. Before presenting these options to the scouts for them to choose, I'm curious which high adventure camp is more difficult, Northern Tier or Philmont?
I know that with Philmont there are a range of trek lengths and once you choose one, that's your trek. I've heard Northern Tier is more flexible.
Whichever one we don't do in 2019 we'll do in 2020.
If your are more interested in the experience of the BWCA than the Northern Tier patch, it's more affordable and enjoyable to use a private outfitter.
Route flexibility. The only reservation is your Entry Point and pick-up. If you get into a poor campsite one night, move on. Bad weather? Tent up for a day.
Leisure. If you're in a good spot, linger an extra day and enjoy the wilderness. Work on Scout skills, teach a merit badge. Unstructured time for campers to bash
