Buri Cave

Búri belongs to the history of lava-cave exploration on Reykjanes. Its scale is worth understanding before treating it as a quick stop: a report presented at the 2006 International Symposium on Vulcanospeleology described nearly a kilometre of large main passage.

What the exploration record establishes

Ed Waters of the Shepton Mallet Caving Club reported work carried out in 2003 and 2005 with Icelandic cave researchers. His conference abstract, on printed page 142, places Búri among the sites surveyed on Reykjanes. It also discusses Flóki, a different cave with a maze-like plan. These are separate named systems; their descriptions should not be combined.

The report gives useful historical evidence of Búri’s size. It does not establish a maintained tourist route, current admission arrangements, or how far a visitor may enter today.

Planning a cave visit

Current access to Búri remains unverified in this guide as of 10 September 2026. Do not assume that an old exploration account supplies permission to enter. Confirm access with the landowner or an operator that explicitly offers this cave before travelling to an entrance.

For a cave trip with published booking arrangements, compare Raufarhólshellir and Leiðarendi. The former has a standard guided visit; the latter requires crouching and crawling. Those choices answer different physical needs, so check the route and equipment requirements along with the departure time.
