Iceland's active volcano attracts thrill seekers and tourists who risk their lives to catch the rumbling noise, the belching fumes and the overflowing lava from the volcano.
"What was most amazing was to hear the rumbling noise," said an exhilarated Aslaug Gudrunardottir, who said she stood only a few meters (yards) from melting lava.
"It was like standing on top of an ancient monster down in the ground. It is a sound that is impossible to imagine," she told AFP back down at the foot of the mountain.
The Fimmvorduhals volcano in the middle of the Eyjafjallajokull glacier erupted on March 21, the country's first such volcanic explosion since 2004 and the first in the Eyjafjallajokull area since 1823.
It forced some 600 people to briefly evacuate their homes in this remote, lightly populated area 125 kilometres (75 miles) east of the capital Reykjavik. But it has since turned into a boon for a local hotel and a few bus firms offering twilight tours -- and a headache for police and rescue workers.
News from geologists this weekend that the eruption may be peaking and could soon "diminish dramatically" sent thousands of visitors rushing to catch a rare glimpse of a real live volcano and the majestic "lava falls", with red-hot burning lava cascading hundreds of metres down a gorge.
Cars stood bumper to bumper in Fljotshlid, across from the glacier, as hundreds of people made their way up to the smouldering peak by foot, snowmobile, helicopter, even motorcycle. A popular hiking trail, it was re-opened last week though police warned anyone taking it they did so at their own risk.
