I have been lucky enough to visit the Jaco Island part of this national park a dozen times over the last few years with Silver Sea.
The Nino Konis Santana National Park is makes up the north-eastern tip of East Timor. Jaco Island is the island off the tip of the mainland and is included within the park. The island does not have a connecting bridge nor roads, and thus can only be accessed by boat.
This is East Timor's first national park, established in 2007. The rather long name is in honour of one of the independence fighters (with FRETLIN) who was born in a village within the park.
Birds seen on the Jaco Island part of the national park include: Dusky Cuckoo-dove, Timor Green Pigeon, Pink-headed Imperial Pigeon, Bee-eaters, Yellow-eared Honeyeater/Timor Meliphaga, Fawn-breasted Whistler, Flame-breasted Sunbird, and Tricoloured Parrotfinch.
At this stage, only Silver Discoverer with Silver Sea visits this island. They include it as their 'outside Australia' stop on their Kimberley itinerary.
