Darjeeling is famous for its numerous Darjeeling black tea plantations. Many tea plantations can be seen here, providing scenic views and the best tea around. The view of the valley is very beautiful and visitors can even bring binoculars to see the beautiful views easily. The climate changes very fast. The possibility of rain or clouds are frequent, so be prepared with rain gear.
Local shops might ask to take photos by wearing traditional clothes and baskets used for tea picking. However, I recommend not buying tea here because the tea leaves will be unprocessed and the price will be too high. In some tea plantations and gardens, tea tastings will be available. I recommend you visit this place to see where tea is grown and enjoy marvelous views.
