Thri­h­nuk­agig­ur Vol­cano (Thri­h­nuk­agig­ur — Three Peaks), locat­ed about 30 km from the cap­i­tal of Ice­land, Reyk­javik, has become a pop­u­lar attrac­tion and place for tourist adven­tures, because it is the only dor­mant vol­cano that allows you to explore it from the inside and get to its heart. In most cas­es, when a vol­cano erupts, the mag­ma cham­ber is filled with lava, which sub­se­quent­ly cools and hard­ens, block­ing the entrance. But at Thri­h­nuk­agig­ur, the lava is believed to have sim­ply flowed back into the bow­els of the earth. The mag­ma cham­ber remained intact and undam­aged, mak­ing the vol­cano an absolute­ly unique place to vis­it.

This place def­i­nite­ly does not fall into the list of the most pow­er­ful vol­canic erup­tions. The vol­cano last erupt­ed approx­i­mate­ly 4,000 years ago, leav­ing an entrance approx­i­mate­ly 4 meters by 4 meters in diam­e­ter lead­ing to a bot­tle-shaped vol­canic vault. The mag­ma cham­ber is approx­i­mate­ly 120 meters deep and is 1×2 meters at the bot­tom. An Ice­landic tour oper­a­tor is now pro­vid­ing a curi­ous adven­tur­ous chance to explore this ancient vol­cano from the inside.

journey into the heart of the volcano
The bas­ket, which holds 5–6 peo­ple, is con­nect­ed to a crane that low­ers it direct­ly into the crater. The 120m descent takes approx­i­mate­ly 7 to 8 min­utes. Once inside, vis­i­tors can spend up to an hour in the heart of the vol­cano, see­ing the beau­ti­ful col­ors on the rock­’s sur­face and appre­ci­at­ing the sheer size. The inte­ri­or space is equiv­a­lent to near­ly three full-size bas­ket­ball courts stacked one behind the oth­er. The height is such that a life-sized Stat­ue of Lib­er­ty would eas­i­ly fit here.

The tour is only avail­able dur­ing the sum­mer, giv­en that the aver­age tem­per­a­ture in the vol­cano is always 6°C. On May 15th, 2013 the next tour was con­firmed. The idea to open Thri­h­nuk­agig­ur vol­cano for vis­it­ing came from Arnie B. Ste­fans­son, a doc­tor in Reyk­javik and a cave world enthu­si­ast. He has been study­ing Ice­land since 1954 and was the first to descend into the crater of a vol­cano in 1974.

Arnie insists that the con­ser­va­tion of caves and vol­canic vaults is not con­ser­va­tion. Rather, it is that nat­ur­al won­ders must be treat­ed with care and respect—they must be made avail­able in the right way. “First it’s a project about con­ser­va­tion, then research, and final­ly edu­ca­tion,” Arnie told The Guardian.
