Khao Lak to Trang Road Trip: Routes, Stops & Safety

The drive from Khao Lak to Trang spans roughly 300 kilometers along Thailand's Andaman coast, combining expressways and scenic secondary roads. This route passes through Phang Nga, Krabi, and into Trang province, offering a mix of limestone cliffs, rubber plantations, and coastal views. The trip typically takes 4.5 to 6 hours depending on stops and traffic.

Start early from Khao Lak's beach resorts, taking Route 4 south toward Phuket, then merge onto Route 402 to bypass Phuket city via the Sarasin Bridge. Continue on Route 4 through Phang Nga town, where the iconic limestone karsts of Ao Phang Nga National Park rise dramatically from the sea. From there, follow Route 4 into Krabi province, passing through the provincial capital before heading east on Route 4 toward Trang.

Safety on Route 4 is generally good, but watch for motorbikes and livestock on rural stretches. Use headlights during heavy rain, and avoid driving after dark due to poor lighting outside towns. Rest areas are frequent, but some may lack amenities.

For families, the Khao Sok Elephant Sanctuary offers an ethical stop for children, while the Krabi Butterfly Garden is a hit with younger kids. Pet-friendly stops include the Pak Meng Beach, but check restaurant polices for pets on terraces.

To combat fatigue, plan stops every 90 minutes. The Hua Thanon rest area near Phang Nga has shaded picnic spots. Consider splitting the drive in Krabi, staying overnight if you want a more relaxed pace.

For hidden gems, diverge onto Route 403 at Thung Wa to visit the hot springs at Khlong Thom, then rejoin the main road. The Namtok Ton Chong Fa waterfall is another off-route treasure requiring a short walk.

Route 4 is the main artery, but shortcuts like Route 403 and 404 offer faster alternatives. Road conditions are generally good with well-marked signage, though rural stretches may have potholes after rain. Expect tolls on the Sarasin Bridge (30 THB) and on the expressway near Krabi.

Fuel stations are abundant along the route, especially in Phang Nga and Krabi. Prices are government-regulated; expect to pay around 30-35 THB per liter for gasoline. There are also EV charging stations in Krabi and Trang city.
