A Swedish tourist was killed Wednesday when he fell 490 feet into the crater of Mount Batur, an active volcano on the Indonesian tourist island of Bali, local police said.

The 25-year-old man slipped as he tried to peer into the crater after a dawn trek to the summit, which climbs to 5,600 feet, on the northeastern side of the island, police added.

"He was looking into the crater, slipped and fell," local police chief Made Oka told AFP.

He said emergency responders were at the scene and were trying to recover the tourist's body using ropes. Police were unable to provide the man's name.

Mount Batur is easy to climb compared to some other volcanoes in Indonesia and is popular with day-trippers on Bali.
