Sai Khao Waterfall National Park sits in Khok Pho district, Sai Khao subdistrict of Pattani province, covering roughly 110 square kilometres of the Sankalakhiri Range — dense, green tropical rainforest. The highlight is the water running down the valley as a string of waterfalls: Sai Khao, Phong Phong, Phra Mai Phai and Aranyawarin falls. This isn't a giant, dramatic cascade. It's a shady, cool, fresh-aired corner of nature that suits an easygoing day out far more than chasing a jaw-dropping view.
Sai Khao Falls — Many Tiers, Cool Clear Water
Sai Khao Falls drops down the valley in tiers, the water clear and cold because it comes straight from rainforest headwaters. The lower tiers have shallow pools you can wade into easily — kids can splash around safely. The upper tiers take a bit more walking along a forest path; it's not far, but the trail gets fairly steep, so shoes with good grip are safer. The water looks best and is most fun right after the rainy season, roughly November to February, when the flow is full and clear. In the dry months it can drop to just a small stream.
- Lower tier — shallow pools you can swim in, with open ground and shade trees to sit under; good for families
- Mid to upper tiers — a walk up the forest path; the falls run over pretty rock shelves and it's quieter than below
- Phong Phong Falls — another, larger waterfall in the park, multi-tiered with stronger flow; it's in a different spot, so you'll need to drive on
Swim safely
Stick to the calm, shallow lower pools. Don't clamber over wet rocks or get close to the tiers where the water runs hard, especially on days when it's raining up on the mountain — flash floods can come fast. If you see the water turn murky or start to run quickly, get out straight away.

A Short Walk Through the Rainforest
Another draw here is the short nature trail that follows the stream and climbs to the upper falls. You don't walk long before you're surrounded by proper rainforest — big trees, hanging vines, the sound of water and birdsong. The air under the canopy stays cool and pleasant all day. It's a gentle hike that most people can manage; you don't need to be a hardcore trekker, and a couple of hours covers it. It suits anyone wanting light exercise while travelling rather than a serious trek.
Prep before you walk
Bring drinking water, a hat and insect repellent. In the rainy season the ground gets slippery and you may run into leeches — closed shoes and socks give you more peace of mind. Carry every bit of your rubbish back out to keep the forest beautiful for the next visitors.
Wat Sai Khao — A Temple Stop on the Way
Before the road up to the park you'll pass Wat Sai Khao, an old community temple that has stood with the village for generations. Inside is a stupa holding the relics of Por Than Nong, a revered southern monk linked to the legend of Luang Pu Thuat. The Sai Khao community is a village where Buddhists and Muslims have long lived side by side — a community-based tourism spot with a temple, a mosque and fruit orchards. Partway up the mountain there's also a large Buddha image you can stop to pay respects to. Since you're driving past anyway, it's an easy add-on.
Respect a two-faith community
Sai Khao is a place where Buddhists and Muslims live together. When you enter the temple or walk through the village, dress modestly, take off your shoes where required, and greet locals with a smile — you'll get a warm welcome in return.
Khao Rang Kiap Viewpoint — Southern Sea of Mist
If you can drag yourself out of bed and want a good view, head up to the Khao Rang Kiap viewpoint inside the park. On early winter mornings there's a chance of catching a sea of mist drifting over the valley and the plains below, with clear-day views stretching out to the town and the Pattani Bay coastline. It's a favourite spot for photographers chasing sunrise. The climb up is fairly steep and you'll need to set off before dawn to catch the mist, so it's worth asking the park rangers about the route and the best timing before you go up.
Getting There, Fees and Where to Stay
The park is about 30 km from Pattani town, an easy 40–50 minute drive. The main route is Highway 409 (Pattani–Yala) to the Na Pradu junction, then turn onto the Na Pradu–Sai Khao road for another 7 km or so to reach the park entrance. The last stretch climbs uphill, so drive carefully, especially on rainy days. There's no public transport that goes all the way in, so most people drive themselves or rent a motorbike or car from town.
- Park entry fee — charged at the usual national park rates (a few tens of baht for Thai adults). There may be an extra vehicle fee; check the current rates at the gate
- Opening hours — open for daytime visits; come from morning to afternoon to get plenty of swimming time and head back before dark
- Accommodation / campground — the park has bungalows, a campground with tents for rent, and a food stall, handy if you want to stay overnight for the morning sea of mist; book ahead through the national park reservation system
- Contact — call 0 7342 0295; the park office is at Moo 5, Sai Khao subdistrict, Khok Pho district, Pattani. Phoning to check the water and weather before you set off is the surest move
When the water looks best
To see the falls in full flow and enjoy the swimming, come at the end of the rains and start of winter, roughly November to February — plenty of clear water and pleasantly cool air. In the dry season (March to May) the water can run low, so if you're set on swimming, phone the park first.
Safety and Cultural Notes
Pattani is in Thailand's southern border provinces. Before you travel, it's worth following the news and official safety advisories, along with the latest situation on the ground — not to worry yourself, but to plan sensibly. Most travellers visiting the nature spots and communities get around as normal; you just want to take reasonable care, the same as you would anywhere.
- Check local news and advisories, plus the weather, before you set off — especially in the rainy season when flash floods are possible
- Dress modestly and respect the Malay-Muslim culture in the community; greet people and ask permission before photographing anyone
- Travel during the day, plan to head back before dark, and tell your accommodation or someone you know where you're going
- Follow park rules — don't litter, don't disturb wildlife, and keep nature beautiful for those who come after you
