Nainativu is a flat scrap of land in the shallows west of the Jaffna peninsula, and its other name, Nagadeepa, means the island of the nagas: the serpents. Everyone we asked called it Snake Island, so that's what we wrote in the notebook. We spent the middle of 5 July 2018 there, and the snakes turned out to be the ones cast in concrete, gold-painted, and standing guard at the gates.
Getting across
You reach it by boat, and the crossing is the best part of the morning. The water between the islands is so shallow and so clear that it turns a flat, unlikely turquoise, and the far shore sits on the horizon as a thin green line of palms with nothing above it.
The island itself is small enough to see in an afternoon, and the way to see it is from the back of a tuk-tuk. Ours was red, black and covered in more stickers than paint, including one across the tailgate reading "Keep the distance" and, along the bumper, "Lamborgini Super 3D". The northern-province plate on the back tells you how far north you've come.
On the way we put our heads into a small Catholic church, cool and quiet under rough wooden rafters. There's a figure of Christ on a plinth, a carved wooden cabinet lit from inside in green, an altar niche ringed with a neon halo, and a wall clock keeping time over all of it. Three faiths share this little island without much fuss.
Nagadeepa Purana Viharaya
The Buddhist temple is signposted off the main road, 500m, on a green board with a Buddha image on it. You know you've arrived because the gateposts are enormous golden cobras, hoods flared, fangs out, coiled around what look like tree stumps, with a pair of gilded lions sitting behind them for company.
Inside the grounds the sea is right there, a few metres past the wall, and the centrepiece is a Buddha seated on a lotus in a red robe with one hand raised, sheltered by a seven-headed cobra that fans out behind him like a canopy. Every head is carved separately, and every mouth is open. The white and gold shrine behind it has "විහාරය" lettered across the front.
Nagapooshani Amman Kovil
A short ride away is the other half of the island's reputation: the Nainativu Sri Nagapooshani Amman Kovil, the Hindu temple that gives Nainativu its pilgrim traffic. The approach runs under a painted archway crowded with figures, and the same green road sign points back the other way to the viharaya, 500 metres.
Under a painted canopy at the front sits Nandi, Shiva's bull, white and pink, wearing a saddle cloth, three tiers of bells and a gold collar, fenced off behind a rail of little gold spearheads. Through the doorway behind him you can see the sea again. On an island this narrow, you're never more than a few minutes from it.
Nainativu was part of the same July 2018 run around the north as Jaffna, and if you're carrying on down the east coast afterwards, Trincomalee and the reef at Pigeon Island are the next water worth getting into.
