Buddha Park (Xieng Khuan) is a weird outdoor collection of huge concrete sculptures of Buddhist and Hindu deities, and real and imaginary beasts. The reclining Buddha is especially impressive. Built in 1958 by mystic Luang Pu Bunleua Sulilat, who left the country after the communist take-over, and in 1978 established a similar but more impressive park (Sala Keoku or Sala Kaew Ku) across the river in Nong Khai, Thailand.
Located 24 km from the city, it’s about 6 km to the east of the Friendship Bridge – hence it’s well worth visiting on the way into or out of Laos if you’re crossing the Friendship Bridge, as this will save a 48 km round trip if you visit from and return to Vientiane. You can hire a tuk-tuk for the entire Vientiane – Buddha Park – Friendship bridge (or vice versa) trip, but taking the public bus #14 is much cheaper. The bus #14 leaves Talat Sao Station (adjacent to the Morning Market) to Xieng Khuan at 15 to 20 min intervals. The timetable is painted on the wall near the ticket office. Fare is 6,000 kip one-way, and it is no problem to flag down a bus on the way back or to the Friendship Bridge.
Note that it is customary to pay when getting off the bus. The buses can be dilapidated minibuses without air-conditioning or new air-conditioned coaches sponsored by a foreign country. Get off at the Friendship Bridge Thai boarder crossing and hire a tuk tuk for the rest of the way. The tuk tuk stand charges 80,000 kip for a round trip, or 40,000 for one way (tuk tuk drivers readily produce a flyer quoting 200,000 kip; negotiating down to 120,000 is possible). These prices are for the whole tuk tuk so it may be much cheaper if you are in a group or tag along with some fellow travellers.
The Buddha Park entrance fee is 5000 kip and an additional 3000 if you plan on using your camera.
