Beyond the national park, Khao Yai has a handful of vineyards for an enjoyable wine tasting session.
Among countryside roads and vast fields of sunflowers, Khao Yai has a few vineyards Prapatsorn, Supatra, Granmonte. All these, although nothing in comparison to Tuscany or Napa, are huge and Thailand's best wineries. They offer delicious whites and reds both. You can rent a car or motrobike from Pak Chong to drive around these farms and vineyards.
