Khao Yai is the sort of place that makes a short trip feel bigger than it looks on a map. Drive out of Bangkok, switch from city traffic to mountain roads, and in a couple of hours you'll experience a dramatic change from the drab city buildings to natural forests, meadows, vineyards, and lush farms. A weekend in Khao Yai will show you Thailand in a different light because nature is not confined to one area here, but closely related to farming, food, tourism, and local business.
