Nicaragua: Mombacho Volcano
Mombacho is an extinct volcano in Nicaragua near Granada. It is over 5k feet high and rises steeply from only about 1k feet. As you ride in a special 4WD monster trucks up the 45% incline, you pass thru 3 ecosystems, finally arriving into a cool cloud forest on top. There are 85 species if orchids, 45 species of butterflies, and 12 species of snakes just for starters. The hike around caldera is spectacular, with views down into forest overgrown green abyss as well as out to the lake Nicaragua with its 365 islands, the towns, and other volcanoes.
