Icelanders discovered Búri cave in May 2005. The cave lies in the Leitarhraun lava field on the <a href="https://www.icelandtravel.is/the-reykjanes-peninsula/" target="_blank" rel="noopener">Reykjanes peninsula</a>.  Over a kilometre in length and 10 meters (33 ft) wide, the cave&#8217;s innermost portion is an impressive 17-metre (55 ft) long vertical pit that a created from a lava &#8220;waterfall.&#8221; Natural ice sculptures and icicles adorn the entry chamber during winter.
Búri cave is one of the most impressive known lava tubes in Iceland. It is about 5.000 years old. The cave has everything you seek in these wonders of nature. This cave is a truly cave explorer&#8217;s dream and offers some great photo opportunities.
The cave is almost 1 km long. Additionally, many chambers are enormous, over 10 metres high and wide. The sheer size of these chambers and the variety of many halls astonishes many explorers. Each hall seems to exhibit more awe-inspiring subterranean landscape than the last.
<h2>Spelunking in Búri cave</h2>
While Búri is among the world&#8217;s largest known lava tubes, it is narrow in places. Spelunkers might find it a little tricky to traverse.  Therefore, only people who are reasonably fit and comfortable in confined spaces should explore Búri cave. We also recommend that visitors wear waterproof clothes and good shoes.
