A working tea estate visit in the Nuwara Eliya region is one of the most accessible and genuinely interesting things to do in the Sri Lankan highlands. The estate walk takes you through the plucking rows and past the weighing stations with the pickers at work and the factory tour that follows – withering, rolling, oxidising, firing – ends with a tasting session of single-origin Ceylon teas at the estate tearoom, giving a complete picture of where Ceylon tea actually comes from and what makes it different.
