We are fairly outdoorsy and have 2 DCs. The youngest is 16 mo.
We used a sling, although I'm not a huge fan, so in the early days it limited us a bit. We now use a backpack carrier and ds loves it and loves our little hikes!
We don't camp, so can't comment on that, but we do like hiking and we found that we have curbed the length of some of our walks and days out tbh. We still go on them, but we might do paths or country parks and limit it to 6 mile max. We like a walk where there is a cafe or pub in the vicinity so we could change ds or feed him, or I could go to the loo, get a sandwich etc. we also look for places with adventure playgrounds. Or at least some swings so the kids can get some fun too.
Our 9 yo ds has always been used to us doing this and is now quite a seasoned walker. Over the years we've bought nature spotting books, binoculars, and other stuff to keep him occupied.
With a tiny baby you just need to see how it goes I guess. Find what you're comfortable with. Start local, make sure you have all the gear you need and be prepared to cut it short sometimes.
I don't want to sound pessimistic, but I reckon if you start with fairly low expectations, that's a good thing!
Good luck!
