The Short Answer
A private city tour by tuk-tuk in Negombo is the cheapest format, typically $42-60 for 1-2 people. A private tour by air-conditioned car runs more, $97-117 for 1-2 people, stepping up roughly $95-190 per added traveller. A private boat safari (lagoon sunrise/sunset, the fishing village) runs $60-102 for 1 person, roughly doubling per added traveller. A multi-day private trip to Sinharaja Rainforest runs $176 solo, doubling for a second traveller.
