How to Get To &
Around Rayong

For travelers who don't drive, buses and vans are the most economical and straightforward way to get to Rayong. Eastern-line coaches depart mainly from Ekkamai bus terminal, with some companies also departing from Mo Chit 2, running several times a day from morning until evening. It takes about 3 to 3.5 hours to reach Rayong bus terminal in town. Vans also depart from Ekkamai and other city pickup points, and are usually a bit faster since they make fewer stops, though some departures wait until the van is full. Bus fares run about 180 to 260 baht, and vans about 200 to 250 baht per person, varying by company and destination.

The thing to plan around is your destination — if you're heading to Koh Samet, choose a route that goes directly to Ban Phe pier for the most convenience, since you can walk straight to the ferry ticket counter after getting off. But many routes only go as far as Rayong bus terminal in town, which is still about 20 kilometers from Ban Phe, requiring another leg by songthaew or local taxi. Ask clearly when buying your ticket whether the bus reaches Ban Phe or only the town center. During long holidays and festivals, tickets sell out quickly, so booking ahead through the bus company's website or app helps lock in a seat and departure time — and it's worth allowing extra time for heavy traffic leaving Bangkok on Friday evenings.

If you're traveling as a group or family and planning to visit multiple spots, driving yourself is usually the most cost-effective and flexible option. The main route is Motorway Route 7 from Bangkok toward Pattaya, then continuing on Highway 36 into Rayong town and Ban Phe. The distance is roughly 180 to 220 kilometers, taking about 3 hours in normal traffic. The road is wide and in good condition for almost the entire route. The main cost is fuel plus motorway tolls, which — split among several people — works out cheaper per head than bus tickets, plus you get the freedom to manage your own schedule and stop at places along the way.

The clear advantage of having a car is being able to conveniently visit spots spread far apart on the mainland — fruit orchards around Ban Khai and Taphong, the golden mangrove fields and Prasae river mouth community in Klaeng district, Mae Ramphueng beach, or Mae Pim beach. Public transport doesn't reach these conveniently. But there are a few things to keep in mind: during long holidays and festivals, traffic gets heavy both at the motorway toll gates and entering Rayong town, potentially adding several hours to your trip. Another point is that if you're heading to Koh Samet, cars can't go onto the island — you'll need to park at a lot near Ban Phe pier, which charges a daily parking fee, and lots fill up fast during peak periods. It's best to arrive early and check the parking rates and security of the lot before leaving your car.

U-Tapao airport sits in Ban Chang district, Rayong province, between Pattaya and Rayong town, about 30 to 40 kilometers from the town center. That makes it an appealing option for travelers flying in from other provinces or countries, since they don't need to land in Bangkok and then spend several more hours on the road. The airport handles some domestic routes as well as some international flights, making it a good fit for anyone who values cutting road travel time and wants to start their trip in Rayong or Pattaya quickly.

What's worth understanding realistically is that domestic flights into U-Tapao are still limited, and schedules can change seasonally. Most Bangkok-based travelers still prefer taking a bus or driving, since it's more convenient and cheaper than flying. After landing, you'll still need to arrange your own transfer into Rayong town or to Ban Phe pier, since there isn't extensive public transport coverage. Main options are airport taxis, private transfers, or renting a car at an airport counter. It's worth planning and booking a transfer in advance, especially if you land in the evening, since public transport becomes even harder to find. In short, U-Tapao is a great fit for travelers coming from far away who don't want to route through Bangkok, but for Bangkok-based travelers it's usually not the cheapest or most convenient option.

Koh Samet can only be reached by boat, and the starting point is Ban Phe pier in Mueang Rayong district. There are two main types of boats to choose from. The first is the regular passenger ferry, the cheapest option at about 100 to 200 baht per person round trip, taking roughly 30 to 40 minutes. The trade-off is that it usually waits for the boat to fill up before departing, and most drop passengers at Na Dan pier, the island's main pier. The second option is the speedboat, which is much faster at about 15 to 25 minutes and can drop off directly at several bays — a good fit for anyone staying at a beach far from Na Dan pier, or for groups chartering their own boat, though the price is higher at around 400 to 600 baht per person.

Something many travelers don't prepare for is the entrance fee for Khao Laem Ya-Mu Ko Samet National Park, which is charged separately from the boat fare and collected at a checkpoint on the island. Thai and foreign visitors pay different rates, so it's worth setting aside cash for this separately. Boat schedules run from morning until evening, with fewer late-night sailings or requiring a private charter, so it's worth checking the last boat time if you're doing a day trip. Another factor is monsoon season, roughly July through October, when rough seas can cause some sailings to be canceled or delayed — it's worth building in some flexibility and checking the weather. Booking a boat package along with accommodation or a tour in advance through an online platform makes it easier to compare prices and lock in a boat time and transfer before you arrive, especially during long holidays when the pier gets crowded.

Something worth knowing before you even get on the island is that private cars aren't allowed on Koh Samet. After landing by boat at Na Dan pier, the main pier, getting to the various beaches on the island relies mainly on songthaews and motorbike taxis. Songthaews wait around the pier, running to popular beaches like Sai Kaew, which is close to the pier, all the way to Wong Deuan Bay and smaller bays further south on the island. Fares run about 20 to 100 baht per person depending on distance and whether you're sharing the ride or chartering it. Beaches close to the pier are cheaper with more frequent rides, while beaches further out cost more and may involve a longer wait.

Another option is renting a motorbike to explore the island yourself, at about 300 to 500 baht per day — flexible and economical if you plan to hop between several beaches. But some stretches of road on the island are sandy or steeply sloped, so it's best suited to confident riders who should watch for slippery surfaces and always wear a helmet. If you're not staying multiple days or aren't comfortable riding, taking songthaews trip by trip is usually more economical and safer. A tip from real reviews is to always agree on the price with the songthaew driver clearly before boarding, and confirm whether it's per person or for the whole vehicle. If you're staying at a beach far from the pier, check with your accommodation in advance whether they offer pickup from the pier, since many resorts do — saving both money and waiting time.

If you've arrived in Rayong by bus, van, or plane and want to visit spots outside town, renting a car is the most flexible option. Rayong's standout mainland attractions are spread far apart — fruit orchards around Ban Khai and Taphong, the golden mangrove fields and Prasae river mouth community in Klaeng district, Mae Ramphueng beach close to town, and Mae Pim beach further out. The public transport network doesn't connect these spots conveniently, so having your own car saves time and lets you go wherever you like. Rental shops are available both in Rayong town and at counters at U-Tapao airport, with small cars renting for about 900 to 1,500 baht per day, not including fuel and insurance.

Something worth knowing realistically is that ride-hailing apps like Grab are more limited in Rayong than in Bangkok or major tourist cities. Within town it's fairly easy to hail a ride, but once you're outside town or heading to suburban areas, rides are often hard to find, making it impractical to rely on the app alone. Another option besides renting and driving yourself is chartering a songthaew or van with a driver to take you around for a set trip or day — a good fit for anyone who doesn't want to drive themselves or doesn't have a license, with pricing negotiated per trip or per day. Before renting a car to drive yourself, you'll need a valid driver's license, and it's worth inspecting the vehicle and taking photos of it before accepting it as evidence, plus choosing adequate insurance coverage. If you're planning to visit multiple spots over one to two days, renting a car is usually better value than transferring multiple times or hailing taxis trip by trip.
