Mombacho trail. Mombacho is a stratovolcano in Nicaragua, near the city of Granada. The volcano's two hiking trails, a moderate one that circles the main crater, and another more difficult trail (El Puma), which must be led by a guide. The more difficult trail is the only way to see some features such as the dwarf forest. The trail is almost completely 45 degree inclines and declines for about two miles.
