Breakfast, free morning until transfer time to Tangkoko National Park, then start of a hike to discover the local fauna, in particular "its big star", the tiny tarsius (the smallest mammal on the planet ), but also the black macaque (endemic monkey), some huge hornbills or discrete "couscous" or oposum, even the rare Maleo (bird that lays its eggs in volcanic ash so that they hatch faster). Return to Tomohon at the end of the afternoon, overnight at the same hotel.
