I've been fortunate enough to do 6 very memorable hunts in Africa and the variety of game animals probably puts Africa on the top of the list of memorable hunts. However my last two African hunts were both in Mozambique and I only brought one animal home from each of those hunts.
I think that next to Africa, New Zealand offers the largest variety of available species of animals. In 2014 my GF and I went to New Zealand. We spent the first week with me hunting and the next two weeks driving on the wrong side of the road. It was a great trip except for the rains.
The animals that I hunted on that trip were Red Stag, Fallow deer, Tahr, Chamois, Arapawa ram, and one night I did a predation hunt for Wallabies.
I have done several very memorable hunts in Canada. I believe that all Canadian big game hunts require nonresidents to have a guide.
My first Canadian hunt was in the Mackenzie Mountains in the Northwest Territory. We flew into base camp on a float plane and out to our spike camps in a Super Cub. On that hunt I came home with a great Dall ram, a Mountain Caribou, and a Wolverine. I would also have gotten a Wolf, but an over zealous guide got between the wolf and me.
On my second Canadian hunt I brought home 2 Central Canadian Barren Ground Caribou and a Musk ox. One of those Caribou and the Musk ox made the B&C record book. One night the display of Northern Lights was beyond exceptional.
My 3rd Canadian hunt was the last year that Quebec allowed nonresident Caribou hunting. We flew to camp in a 70 year old Otter float plane. You could spend a lifetime fishing and exploring all of the lakes that we flew over. The camp and staff were great and I met some great other hunters there. I passed up quite a few Caribou bulls until I saw the one that I wanted and he was one of the largest taken that season and also went into the B&C record book.
In 2010 a couple of friends and I went on a hunt in West Texas for Exotics. We hunted several ranches and saw a lot of different animals, but it was more of a shoot than a hunt.
While at the GSCO Convention in Las Vegas in 2017 I booked a Dagestan Tur hunt in Azerbaijan. That is a part of the world that I had never been in and other than me being 71 and not in my 40's like I was for most of my bighorn sheep and mountain goat hunting, those mountains were some of the steepest and highest mountains that I have ever hunted. That was a very memorable hunt and I have a very unusual trophy Tur on my wall to enjoy seeing every day.
In the almost 50 years that I've lived in Montana I've been fortunate enough to have hunted all of Montana's big game species with multiple hunts on most of them and most of those hunts being DIY and many of them with my horses and also many of them solo. Using my horses to get into Montana's backcountry on elk, moose, and bighorn sheep hunts were some of the most memorable hunts that I've done.
For many years I've wanted to hunt a Brown bear in Alaska. Two years ago I fulfilled that dream and although he's not a monster, I got a beautiful Toklat Brown bear on that trip. We didn't see any any moose, but I enjoyed seeing some new and beautiful country, topped off with a couple of days fishing for arctic grayling and catching and releasing at least 150 of them. I would do that trip again.
