Another place I would recommend is the Raj Mahal Inn, in Wadduwa, about 40 km south of Colombo. It’s a small hotel with just 6 rooms, but the big draw there is that it’s clothing optional and caters pretty much exclusively to gay men. It’s a one man operation and the owner Raja is a super nice guy, who is also a trained masseur. Besides the tourists who stay there, local nudists can buy a day pass and come spend some time. Again, mostly gay men, although once while I was there a local straight couple came for the afternoon. There’s no problem inviting the visiting locals to your room, so there’s fun to be had with them, fellow guests, and even the owner himself. It’s just a few minutes walk from a gorgeous beach which was almost empty while I was there. Also it’s conveniently located just steps from the train station. There’s not a lot to see in the town of Wadduwa, but it has all the necessities: restaurants, grocery stores, pharmacies, bank machines, etc. You can easily do a day trip to Colombo from there by train, which I did with a Norwegian guy who was staying there while I was there.
