Skaftafell campground in Vatnajökull National Park is a year-round spot with room for about 400 tents. You can find flush toilets, seasonal tourism services, and even some restaurants nearby. If you're camping with a camper or trailer, there are spots with electricity available. Just remember to register and pay at the camping reception before setting up your tent. And don't forget, no water outside until mid-May due to frost!
