Manado Tua non active volcano is an Island at about 35 min. boat ride from Kima Bajo Resort.
There are several diving sites around it. My favorite one is Pangulingan as we can often see some school of jacks, bat fish, napoleon wrasse, reef sharks and lots of fusilier.
The sloping reef reaches until 35m after that the drop off starts and goes down more than 70m deep. The visibility is all year around between 20-30m. As this diving site is right in the corner of the island often we can have currents coming from different directions, therefore we can go there just when conditions are favorable. However, during your week of diving we should be able to find the right conditions to go there.
