Pai to Fang Road Trip Guide: Mountains, Hot Springs, and Scenic Curves

Pai (elev. 580 m) and Fang (elev. 450 m) are linked by a 92 km route that crosses the Thanon Thong Chai Range via Route 107 and 1265. The drive typically takes 2 hours 15 minutes in dry weather, but you'll likely stop for viewpoints, hot springs, and caves.

The route passes through the Mae Fang National Park, home to the famous Doi Pha Hom Pok, Thailand's second-highest peak (2,285 m). This area is a geological marvel of granite and limestone, shaped by ancient tectonic activity.

Route 1265 is a narrow mountain road with sharp curves and occasional seasonal closures. Check local conditions before departing, especially during the rainy season from May to October.

Road 1265 has numerous blind curves; drive at 40-50 km/h. Guardrails are intermittent, and occasional landslides occur during rains. If you're prone to motion sickness, take a motion-sickness pill before starting.

Children will enjoy the hot springs—supervision is needed around thermal pools. The Fang Hot Springs (Ban Pong Ang) have safe wading zones.

For pets, keep them leashed and carry water; there are rest stops with shade at the national park office and Tha Ton market.

Plan a break every hour. Good spots: Ban Rak Thai's lake (km 20), Pong Arng Hot Springs (km 28), and Tha Ton's riverside cafes (km 50). Fang's town center offers numerous eateries with northern Thai dishes like khao soi.

Fatigue management: use viewpoints to stretch legs and keep hydrated. The drive is scenic but demanding.

Best stops Pai to Fang among locals: the Doi Pha Hom Pok viewpoint at km 35—a short boarded walk from the parking area.

Route 1265 leads east from Pai past Ban Rak Thai and then turns south to join Route 107 near Tha Ton. The total drive is 92 km; it's worth driving Pai to Fang for the scenery, but be prepared for slow going.

• Fuel: Pai has several stations; the next reliable fuel stop is at Fang (around km 45 on Route 107). Carry a full tank.
• Road quality: Paved but narrow in parts; expect potholes after rains.
• Tolls: None on this route.
• Restrooms: Available at hot springs and national park offices; plan stops accordingly.

Ban Rak Thai, a Yunnanese village at km 20, makes a good first stop. It offers a glimpse of the area's Chinese heritage, with tea plantations and a reservoir popular for short walks.

The route's highest point is near Doi Pha Hom Pok at 1,600 m, where temperatures can drop to 8°C in winter (November to February). Pack a jacket.

After Ban Rak Thai, the road climbs through dense forest, with multiple viewpoints overlooking the valleys. Look for signs for Pong Arng Hot Springs (km 28), a natural 125°F pool set in a bamboo grove—a perfect leg bath.

Mae Fang National Park (entrance fee 100 THB) is a UNESCO World Heritage Site candidate for its biodiversity.

Continue to Tha Ton, where Route 107 meets the Mae Kok River. Here, you'll find the Rajamangala Phisek Bridge (built 1994), a long steel bridge with sweeping river views.

Local commerce thrives along the way: fruit stalls sell lychees and mandarins near Fang, famous for its plantations. For a deeper understanding of how to spot such hidden gems, refer to this how to find the best stops and hidden gems between cities guide.
