But nature is completely unforgiving \u2014 active volcanoes in Iceland demand serious respect:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Never approach active lava on your own<\/strong> without checking the current situation. Flows can change direction without warning, and new fissures can open up in seconds.<\/li><li><strong>Volcanic gases are invisible and lethal.<\/strong> No Instagram shot is worth gas poisoning.<\/li><li><strong>Respect all closures.<\/strong> When the authorities close a route, there&#8217;s a very good reason for it. Iceland&#8217;s mountain rescue team (ICE-SAR) have better things to do than recover tourists from lava fields.<\/li><li><strong>Always check<\/strong> <a href=\"https:\/\/safetravel.is\/\" target=\"_blank\" rel=\"noopener\">safetravel.is<\/a> and <a href=\"https:\/\/en.vedur.is\/\" target=\"_blank\" rel=\"noopener\">en.vedur.is<\/a> before heading out.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Get_to_Icelands_Volcanoes_Craters\"><\/span>How to Get to Iceland&#8217;s Volcanoes &amp; Craters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Most of these sites sit directly on or just off Iceland&#8217;s main Ring Road, making them straightforward to reach by hire car. Reykjanes is right on the doorstep of the airport, Keri\u00f0 is on the Golden Circle, and M\u00fdvatn and Krafla are in the north. The best approach is to take them in as part of a full lap of the island. Flights to Keflav\u00edk are available from most major UK airports with airlines including Icelandair and easyJet \u2014 journey times are typically around three hours from London.
