Seeyok Tea Garden was established in 1869. It has a gross area of 406 hectares. Situated on the Indo Nepal border, facing the lovely  Rongbong Valley, shaded by majestic Mount Kanchenjunga.

Locals call this garden "Swek". Mirik, a tourist's delight is just 8 km away. Floods swept away Seeyok's earlier tea factory. But its new factory's first flush teas fetch Seeyok a high premium. Its green teas have a distinctive Darjeeling flavour.

Seeyok has won the World Tea Association's award for the best tea in the World.
