The mountainous, thickly jungled Caramoan peninsula is only 50km or so from Naga, but it might as well be worlds away. Best approached by boat, it can feel as if you're arriving at the Jurassic Park island, with its jagged cliffs, teal sea and pristine strips of sand. The northern coast has a sprinkling of grey-sand beach resorts, the main one being Paniman, which serve as a starting point for island-hopping or relaxation.
The Caramoan is sufficiently remote to have been the location for filming of US, French, Israeli, Danish, Serbian and other versions of Survivor, but the peninsula has become ever more accessible with the paving of the road (it's still better to get here by boat). It's well off the tourist radar but on weekends Filipinos come from the cities for island-hopping adventures, so don't expect to have it all to yourself.
