Take a tour of the spice plantations or gardens in Munnar, Thekkady or Wayanad. Taste some authentic black pepper, cardamom, cinnamon, and the exotic vanilla and explore the farms on a nature walk. Most hotels include these tours in their packages but you can visit on your own too, like Abraham’s Spice garden in Thekkady which costs only Rs 200 to enter. You can also buy spices you like at subsidized rates from the workshop located in the spice garden itself.
