Did you know that Phou Khao Khouay National Protected Area shelters one of Laos’ last remaining wild elephant populations? Just 40 kilometers northeast of Vientiane, this 2,000-square-kilometer wilderness sanctuary remains one of Southeast Asia’s best-kept secrets. With its name translating to “Buffalo Horn Mountain,” this biodiverse haven offers intrepid travelers a rare glimpse into pristine ecosystems ranging from misty mountain forests to cascading waterfalls that few international visitors ever experience.
Getting There & Planning Your Journey
Reaching Phou Khao Khouay National Protected Area is relatively straightforward from Vientiane, Laos’ capital city. The park entrance is approximately 40 kilometers northeast of the city, making it accessible as either a day trip or multi-day excursion.
From Vientiane:
- Take Route 13 South and turn left at the 90 km marker (just before Thabok)
- Follow the road for 5 km to Ban Houay Leuk village
- Continue following signs for 1 km, turning right and crossing an iron bridge over the Nam Leuk river
- Drive another 5 km to reach the park checkpoint where you’ll pay the entrance fee (5,000 kip per person)
Transportation Options:
Private Vehicle
Renting a sturdy SUV or truck is recommended as some roads within the park can be rough, especially during rainy season. This option provides the most flexibility for exploring.
Guided Tour
Several tour operators in Vientiane offer day trips or multi-day excursions to the park, including transportation, guides, and sometimes meals. This is the easiest option for first-time visitors.
Public Transport
Budget travelers can take a public bus from Vientiane to Ban Hatkhai village, then hire a local tuk-tuk or motorbike taxi to the park entrance. This requires more planning but costs less.

Getting Around Locally

Navigating Phou Khao Khouay National Protected Area requires some planning, as the park spans a vast area with varying terrain. Here are your best options for exploring the park:
Hiking
Many of the park’s attractions are accessible via hiking trails of varying difficulty. Local guides are recommended for longer treks, as some trails are poorly marked. The Orchid Trek from Ban Hatkhai village is particularly popular.
4WD Vehicle
A 4-wheel drive vehicle is essential for reaching some of the more remote areas, especially during or shortly after the rainy season. The road to Tad Leuk and Tad Xay waterfalls can be challenging.
Guided Tours
Local guides can be hired at Ban Hatkhai village (approximately 100,000 kip for 1-3 people). They provide valuable insights about the park’s ecology and can help you spot wildlife you might otherwise miss.
Where to Stay

Accommodation options in and around Phou Khao Khouay National Protected Area are limited but offer authentic experiences. Most visitors choose between staying in Vientiane and making day trips to the park or immersing themselves in local culture with homestays.
Ban Hatkhai Village Homestay
Experience rural Lao life in a traditional open-plan house. Expect basic but clean accommodations with bedding, mosquito nets, and home-cooked meals. Costs around 30,000 kip for the homestay plus 30,000 kip for meals.
Contact: Mr. Khamoune or Mr. Bounthiang at (020) 224 0303
Tad Leuk Visitor Center
Basic overnight facilities are available, though reports suggest the quality has declined in recent years. Not recommended for comfort-seeking travelers, but convenient for early morning wildlife spotting.
Vientiane Accommodations
Many travelers prefer to base themselves in Vientiane, where a wide range of hotels and guesthouses are available, and make day trips to the park. This offers more comfort but less immersion in nature.
Dining & Local Cuisine

Food options within Phou Khao Khouay National Protected Area are limited, so planning ahead is essential. Here’s what to expect:
- Village Homestays: If staying in Ban Hatkhai, your host family will prepare traditional Lao meals featuring sticky rice, fresh vegetables, herbs, and occasionally fish from the local river.
- Pack Your Own: For day trips, bring plenty of water and food supplies from Vientiane, as there are few places to purchase food within the park.
- Local Specialties: If you have the opportunity, try “mok pa” (fish steamed in banana leaf) and “laap” (minced meat salad with herbs) prepared by local families.
- Visitor Centers: The facilities at Tad Leuk and other locations have limited or no food available, so don’t rely on purchasing meals there.
