We were a business group, but it is quite apparent that there are lots of activities tailored for the lonely gentlemen coming in from Malaysia and Singapore.
From the heart of the town's massage parlours and bars (Pramuka and Setiabudi) to the outskirt Garden villas... The island itself has some places for adventure seekers, such as Gunung (Mount) Karimun, where both locals and tourists have a hiking trail leading up to the highest point on the island.
The worst place to be in as it is crawling with call girls, thieves and very unhygienic. Prepare lots of cash as there is tons of hidden cost.
