Walk or see if you can hitch a ride with a 4WD or one of the locals that are heading up to tend to their crops. While technically a main road, RT1 gets pretty rugged after Malaetoli village. The circular lake is spectacular with sheer sides all around. At the end of WWII the Americans reportedly dumped a whole lot of military hardware at the bottom of the lake before leaving the island. At dusk a colony of bats on the far side of the lake stretch their wings and start flying out for the evening - quite a sight.
