A steep trail reaches here the crater rim, partially strengthened with concrete steps to reduce erosion. Great Panorama from here. The summit is closer if continuing anti-clockwise on the loop trail around the rim
The walk around the crater is worthwhile, but its length shouldn't be underestimated. It's about 7 kilometers along the crater rim, which can be long and strenuous in normal temperatures. Therefore, bring plenty of water and provisions, as there's nothing available along the way.
