Dambatenne Tea Factory sits among the plantations above Haputale, in the country long associated with Sir Thomas Lipton. Tea grown around these hills helped build the Lipton name, and the factory remains one of the better-known places to see the processing side of Sri Lanka's tea country.
It pairs naturally with Lipton's Seat. Go for the landscape as much as the machinery: the road up through the estates is part of the experience.
