Best trip Ive ever made was 13 days in the Wind River Range (WY) with my 19 year old son. Off the grid, self supported, covered about 75 miles at high elevation, and fished our way through the whole trip. All those campfire evenings, working together on navigation, and side-by-side tent time were priceless. I wouldn't swap it for a dozen trips to Paris.
2 week back pack hunts in Westland NZ with a recurve.
Another memorable trip was the Arnhemland coast by boat from Nhulunbuy to Elcho Island in the Northern Territory. Fishing and hunting buffalo and pigs.
Wow good question. I've been blessed with a lot. Probably packrafting through central British Columbia on a river that had probably never been run and then backpacking over Mt. Edziza (an extinct volcano) is right up there with my favorite hunting trips. Actually I did a bunch in the Canadian Rockies for a while.
