Tak is a beautiful province almost entirely off the tourist map; consequently, visitors looking for true Thai hospitality and a peek at everyday Thai culture, unspoiled by the influences of mass tourism, are in for a real treat.
While there are few tourist oriented sights and activities, this does not mean Tak is absent of attractions; in fact, Tak features spectacular natural attractions, including jungle covered mountains filled with exotic animal life, many hill tribe villages living traditional lifestyles, and opportunities to go white water rafting, play golf, or visit a gibbon rehabilitation center.
