There's a lot to see both in and around Hue, some of which are difficult to get to on your own. If you want to make sure you see all the city has to offer, you may wish to book a tour in advance through Viator or Exotissimo. Viator offers a full range of full day and half day tours, excursions and even airport transfers in many of Southeast Asia's popular tourist destinations. By booking in advance through Viator, you'll be sure to get the tours you want, and you won't be surpised at the cost. Exotissimo offers mostly multi-day packages that cover several cities.
