Kalimantan or Sabah or Sarawak on the huge island of Boreno?We're starting to get tempted by Raja Ampat .. and hoping for one or two landbased dive resorts. We had reached out to an operator that was thinking of adding some things like Borneo and Java for land stuff ...
If you can line up R4 + Sangalaki(Kalimantan) + Sipadan(Sabah) + Iban Long House and the Caves in Sarawak. That would be a fabulous trip.
