Is your goal a backpack trip or a hunting trip? If your a first timer and want to go elk hunting I would personally recommend you base camp it. Until you know an area you maybe dedicating time to an area with no animals. Elk move a lot and there’s a lot of country that doesn’t have good elk numbers. It’s a lot easier to drive 10 miles down the road and hunt a different spot than hike out 5 miles move and hike in 5 miles again which will really cut into your hunting time. Also if you’ve never packed an elk out you’ll be in for a surprise if you’re solo and pack it out 7 or more miles with a camp.
If the backpack experience is what you want go for it, but I would ask if it’s the experience or hunting you want. I learned a few years ago that elk are not always way back and you can’t kill them if they’re not there.
