The ride up was fun, in a 4WD truck, but was a bit of an indulgence at $16 a head. Still, we timed our trip a bit late, and walking up looked like a bad idea as the day wore on. At the top, we we're told that to walk the longest trail you had to pay another $17 mandatory fee for a guide. Cheeky. So we went ambling around the rest of the crater area and had a great view and saw our first fumaroles (volcano farts!). Despite the cost, they have not been investing much in upkeep, and I hope that they do, as paths are getting quite eroded, and the tree filled main crater really is stunning.
