Similarly if you plan to carry your tent, sleeping bag, camping mat and everything else with you (not take it all in the car), it’s worth doing a test run to check everything fits in your rucksack and that you can still stand up and walk whatever distance you’re going to need to walk carrying it all.
Check all the details of the camping location you plan to visit – if it’s an organised site be particularly careful to note any restrictions on opening days and times and phone ahead to be sure there’ll be space for you.
Check reviews of the site you plan to visit to look for any frequently mentioned ‘issues’ and think about ways you can avoid such a problem happening to you.
Finally, Enjoy!
