One of the most important changes here is to know, as of 2015, it is illegal to camp in tents, trailers, caravans, campervans, or anything of the like, outside of a designated campsite UNLESS there is written permission from the landowner.
Off-road driving is strictly forbidden in Iceland.
Before long, it is expected that all off-road camping in Iceland will be illegal.
You are also not permitted to camp outside of designated areas within any of Iceland’s three National Parks: Þingvellir National Park, Vatnajökull National Park and Snæfellsjökull National Park. To reiterate, If you are in a campervan, caravan, tent trailer or something similar, including a 4X4 vehicle with a tent on the roof, you must retire each night to a campsite no matter where you are in the country.
Other locations where camping is forbidden, in alphabetical order, include Álafoss, Dimmuborgir, Dyrhólaey, Fjallabak, Hverfjall, Kirkjugolf, Mývatn and Jökulsárgljúfur. Many other locations quickly add to this list, so make sure to forever be updating yourself as to where is and is not permissible for overnight camping stays.
