Welcome to Gunung Kelud
To get to the crater itself you have to walk through a 200m tunnel, built under the Japanese occupation. A torch (flashlight) isn't necessary but will reveal many bats. To get the best perspective of Kelud you need to hike a steep path up the side of the crater.
Entrance to Gunung Kelud is controlled at a gateway 10km before the summit because of the active nature of the beast.
There’s no public transport to Kelud. The easiest way here is to hire a car or ojek from Blitar. After bargaining, the latter will do a half-day return trip via Panataran for around 100,000Rp.
