This tour is one of the most amazing and enlightening you can take on the Osa. Everyone who takes it raves about it. The dynamic duo of moonlight exploration use rechargeable batteries for your top quality headlamps, a must for eco night tours as the throwaway kind pollute our rivers and streams all over the Osa. One disposable battery can contaminate tens of millions of liters of water. The bug lady will change your perspective forever on insects and spiders and things that go bump in the night.
