Things I wish I’d known.
Hiking-camping is different to car-camping. If you can park next to your tent, you’re golden.
Tents, find a big outdoor shop with a display and have a poke about. Bear in mind that small sleeping areas are considerably warmer than large ones. You’ll be surprised how cold it gets at 4am.
The first time you put up a new tent, it’ll take you twice as long as you think; try not to be doing it in the dark.
Gellert are purveyors of the porous. I’ve never bought anything from them that hasn’t leaked or otherwise just been crap. Buy Gellert, buy twice.
Double inflatable matresses seem a great idea till you use one in a tent. Everytime one of you moves, the other gets bounced around. They go down in the night (though, y’know, Gellert) and they don’t insulate you from the ground particularly well so it’s like sleeping on an iceblock.
The alternative to the airbed is the Thermarest-style camping mats. These are ace, but really expensive. The answer is the Alpkit mats. I’ve got an old-style one (their ‘Fat Airic’) and it’s been amazing.
Avoid the cooking stoves which look like briefcases, they’re crap. Or at least, the one I bought was, but it might have been Gellert. I ended up getting the GoSystem Trek and, a couple of years later when I set fire to it, bought two more. You’ll be hard pressed to get better for the money, they’re ace.
Lights, lights, lights. Get a lantern and head torches. I’d also suggest hats or Buffs for midge-protection.
