Krachiao Flower Fields Chaiyaphum
Blooming in the rains, Jun–Aug

🔄 Updated 21 Jun 2026

The krachiao (also called the Siam tulip, or wild curcuma) is a perennial whose bulb stays buried underground all through the dry season. Once the first rains soak the ground, pink-purple blooms push up across the whole field at once. They last about two months, then fade away until the following year. So seeing the fields at their best comes down purely to the timing of the rain — if the rains come late one year, the flowers bloom late too. Checking before you go is always the safest move.

When do the krachiao flowers bloom, and how to check first

The krachiao bloom season in Chaiyaphum runs from about mid-June through late August each year. The fields are usually at their fullest and most spectacular in early to mid-July, which is exactly when the province holds its krachiao flower festival, with tram services and extra visitor facilities laid on. The flip side is that this is also when the crowds are biggest.

• Check the parks' pages before you go — both Pa Hin Ngam and Sai Thong have Facebook pages that post real photos of the fields periodically, showing what percentage is in bloom. Seeing the actual state of things beats guessing.
• Call the rangers — Pa Hin Ngam 0 4405 6141 · Sai Thong 08 9282 3437. Ask which field is blooming best and how busy your travel day is likely to be.
• Avoid the very start and end of the season — early June and the blooms may still be sparse; late August and they start to fade. If you can choose, aim for mid-season to catch the fields at their fullest.
• Expect rain — coming in the rainy season means rain, plain and simple. Pack a rain jacket and waterproof bags for your camera and phone.

Pa Hin Ngam vs Sai Thong — which one to pick

Chaiyaphum's big krachiao fields sit in two national parks, in different districts a fair distance apart. Most people pick one or the other per trip; if you have two days, do both. Both sit on the Phang Hoei mountain range, so the air is cooler than down on the plains — but their characters are clearly different.

• Want it easy, bringing older relatives or kids — go for Pa Hin Ngam, with its tram and flat paths so you don't have to walk far.
• Want the shot of Pha Ham Hod jutting over the valley — that's Sai Thong. Pha Ham Hod is the most sought-after photo spot here, but it takes a decent walk to reach.
• Driving yourself, ideally a slightly high-clearance car — some access roads to Sai Thong are rough dirt tracks that get slippery in the rain. A sedan can make it but go carefully. Pa Hin Ngam's roads are better.

Pa Hin Ngam krachiao field — easy walking, with a tram

At Pa Hin Ngam, the krachiao field starts just past the car park. You walk up a gentle slope along a set path for about 1 km, with pink-purple blooms scattered through the grassland on both sides the whole way. During the festival the park runs a tram from the car park to the field entrance, so anyone who'd rather not climb the slope can ride up — it's only a few dozen THB. The nice thing here is you can do everything in one place: the Lan Hin Ngam rock field with its oddly shaped formations and the Pha Sut Phaendin viewpoint are right nearby, an easy walk on from the flowers.

Sai Thong krachiao field — Pha Ham Hod and Pha Pho Mueang

Sai Thong is in Nong Bua Rawe district, with krachiao fields spread across several spots along the western side of the Phang Hoei ridge — both pink blooms (Bua Sawan) and white ones (Bua Thep Apsorn). The walking trail runs along the cliff line, passing several standout points. The star here is Pha Ham Hod, a finger of rock that juts out over the valley at around 860 m elevation. People love to stand at the tip for photos that make them look like they're floating in mid-air — the results are seriously vertiginous. Nearby are Pha Pho Mueang and Pha Phloen Jai, both with wide views. Early in the morning after rain, if the sky clears, you've got a chance of catching a sea of mist drifting in the valley.

• Pha Ham Hod — the highlight photo spot. You stand at the tip of a rock jutting out over the valley, so take great care: the wind is strong and the surface gets slippery in the rain. Go one person at a time, and don't jostle for space on the rock.
• Pha Pho Mueang · Pha Phloen Jai — wide viewpoints along the trail, with valley views stretching as far as you can see. Good spots to sit, rest, and catch the breeze.
• Several fields — Bua Sawan fields 1–4 are spread along the trail, so you can take in several in one round. They don't all peak at the exact same time, so ask the rangers which field is looking best.
• Longer, rougher trails — walking the cliff line takes several hours if you cover it all. Wear sneakers or hiking shoes and bring water.

Photo spots and the best light

• Early morning, 6:00–8:00 am — soft light, the field still empty, with a chance of thin mist and dew on the petals. It's the prettiest window of the whole day.
• Low angle, close to the flowers — krachiao blooms sit around knee height, so crouch for close-ups that set the pink-purple petals against the green grass for a clean shot.
• Wide angle for the whole field — stand at the start of the path to capture the field stretching toward the mountains. Pa Hin Ngam gives you a long field; Sai Thong pairs the field with the cliffs.
• Pha Ham Hod (Sai Thong) — the angle of someone standing at the tip looking like they're floating in mid-air. It's the most sought-after shot here, but do it carefully.
• The World Cup trophy rock (Pa Hin Ngam) — the icon boulder in the Lan Hin Ngam rock field. Stop for a photo right after the flowers, since it's all in the same place.

Entry fees, opening hours, and what to bring

• Opening hours: both parks are open daily 6:00 am–6:00 pm. During the festival, people start arriving from early morning.
• Entry fee: Thai adults about 40 THB, children about 20 THB · foreign adults about 200 THB, children about 100 THB.
• Vehicle fee: about 30 THB per car · the tram up to the field at Pa Hin Ngam during the festival adds about another 30 THB per person.
• What to wear: sneakers or hiking shoes, a rain jacket, a hat, drinking water. Some sections turn to slippery mud in the rain.
• Waterproof your camera gear: rain can hit any time in the wet season, so a dry bag or a rain cover over your camera bag helps a lot.
• Entry and tram rates may change with the National Parks Department's rules each year, so check with the park again before you go.

Getting to the krachiao flower fields

Both parks are in the southwest of the province. Pa Hin Ngam is in Thep Sathit district, about 110–140 km from Chaiyaphum town, roughly a 2-hour drive. Sai Thong is in Nong Bua Rawe district, a little closer at about 70–90 km. Neither has public transport running directly to the park, so driving yourself or renting a car is the way to go. During the festival there are some day tours and overnight tours from Bangkok.

• Pa Hin Ngam from Chaiyaphum town: take Highway 201 south, then Highway 205 toward Thep Sathit district, then turn onto Route 2354 following the signs to Pa Hin Ngam. The final stretch is a winding mountain road — drive carefully in the rain.
• Sai Thong from Chaiyaphum town: take Highway 225 toward Nong Bua Rawe district, then follow the signs into Sai Thong park. Some access roads are dirt and slippery in the rain, so a slightly high-clearance vehicle drives more comfortably.
• From Bangkok: head via Saraburi–Lam Narai, then Highway 205 to Thep Sathit — about 270 km to Pa Hin Ngam, roughly a 4-hour drive.
• From Nakhon Ratchasima (Korat): Pa Hin Ngam is about 140 km away, an easy add-on trip from Korat.
