While the lava flow appears like a white water flowing streams and brownish mud they form into solidified lava crystals that reflect sharp sparks when hit by rays.The low gas content lava glows to extreme red-orange pool during the dark within the crater rim and around the solidified peaks of volcanic lava cones creating a spectacular display. The last minor explosions of Lengai are reported to have been witnessed by a group of touring climbers in the beginning October 2005. There is a beautiful camping base for climbers and hikers. Munge River water falls provides the most desired power shower after the tedious climb.
