The main route runs south from Ranong on Highway 4 (Phetkasem), passing through the Takua Pa stretch of Phang Nga, then turns onto Highway 401, which cuts through Khao Sok National Park into Surat Thani city. From the city you carry on down to Donsak pier, about another hour, to cross to the islands. No private car? No problem — Ranong–Surat minivans run every hour.
Route overview and getting there
Ranong to Surat Thani is around 220–230 km, roughly 3.5 hours by car or minivan if you don't stop. But this plan stops on purpose, because there's good stuff along the way — a roadside waterfall near the start and the Khao Sok forest in the middle. Blasting straight through means missing the views.
- Ranong–Surat Thani minivan — departs Ranong bus terminal roughly every hour, around 07:00–17:00, fare about 200–250 THB, journey ~3.5 hrs, dropping you at Talat Kaset 2 in Surat city.
- Self-drive — the most flexible option for this trip, since you can stop at the waterfall and Khao Sok as you like. Budget roughly 700–900 THB for fuel round trip.
- Onward to Donsak pier — from Surat city it's another 65–70 km, ~1 hr, to Donsak pier. The ferry companies (Lomprayah/Raja/Seatran) run connecting minivans to the pier.
- Ferry to the islands — Donsak→Koh Samui ~1.5 hrs / Donsak→Phangan ~2.5 hrs / Lomprayah's fast boat continues to Koh Tao.
Timing it so you make the boat
The last Donsak ferry is usually around 17:00–18:00. If you leave Ranong late and make several stops, you may not catch a boat the same day. That's why we have you overnight in Surat and board a morning ferry the next day — easier, and no rushing.
Book the activities in your Ranong trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.

Enjoy the island, then plan the way back
Stops and standout eats along the way
Here's our shortlist, ordered the way you'll meet them on the route from Ranong all the way to the islands. We've added rough prices and opening hours where we could check. These change with the season, so confirm again before you go to be sure.
Dim sum breakfast in Ranong town
Start the day with hot Ranong-style dim sum — shumai, char siu, pork blood soup. Morning eating is a part of this town's culture. Fuel up before the long drive.
Punyaban Waterfall
A roadside waterfall on Highway 4 just before you leave Ranong. Pull over for photos with no long walk needed — big parking area, restrooms and shops. Best flow in the rainy season.
Limestone karst views on Highway 401, Khao Sok
The prettiest part of driving across the peninsula — limestone karsts lining both sides of the road through Khao Sok National Park. Drive slow and roll the windows down.
Cheow Lan Lake raft trip (optional)
If you have a spare day, turn into Khao Sok and overnight on a raft house on the emerald lake. Park entry is 30 THB. It's a detour plenty of people happily make because it's worth it.
San Chao Market, Surat Thani
Surat's well-known downtown street-food market — rich crab curry noodles, crispy-skin fried chicken, rice with curry, khanom jeen. An easy place to graze for dinner.
Southern-style crab curry khanom jeen
A Surat specialty — rich, boldly seasoned sauce. Several shops in town open from morning into the afternoon, and some let you refill the sauce. Easy on the wallet too.
Surat Thani oysters
Surat is known for big oysters. Seafood restaurants in town and around Kanchanadit serve large ones — eat them fresh with southern-style condiments.
Old-school restaurants in Surat city
Want a sit-down feast? There are several long-running Chinese-seafood restaurants. Standouts include sour curry with sea bass and turmeric-fried featherback fish — a good dinner before the ferry.
Donsak pier, where island life begins
The gateway to the Gulf islands, with cafés and snacks while you wait for the boat. Arrive about half an hour before your sailing so you're not scrambling at check-in.
Pick the island that fits your style
Once you've crossed to the Gulf side, there are three main islands from Donsak — Samui, Phangan and Tao. Each has its own character. Pick based on the kind of trip you want.
Koh Samui
The big island with full amenities — Chaweng and Lamai beaches, loads of restaurants and cafés, and an airport so you can fly home. Good for families and anyone who wants comfort.
Koh Phangan
Home to both the Full Moon party scene and quiet beaches on the north side. This island balances fun and chill, ideal if you want both modes in one place.
Koh Tao
The Gulf's diving capital — cheap dive courses, lots of dive sites, and the gorgeous Koh Nang Yuan. You'll need to take Lomprayah's fast boat one more leg to get here.
Book the ferry ahead in high season
In high season (Nov–Apr) and on long weekends, boats to Samui and Phangan fill up fast. Booking online with Lomprayah, Raja Ferry or Seatran in advance gives you peace of mind, especially if you're taking a car across too.
