What makes Rayong fun is that you can do several very different things in one province. With 3 days and 2 nights, we'd split it into three parts: on day one, walk the Yom Chinda old town and stay overnight on the mainland by Mae Ramphueng Beach; on day two, take the ferry over to Koh Samet for one night and soak up the quieter evening and early-morning sea; then on day three, head back to the mainland to walk the Thung Prong Thong mangrove forest at Pak Nam Prasae, stop by Laem Mae Phim Beach, then finish with seafood and souvenir shopping.
Before you go: what to know
- Ferries to Koh Samet leave from Sri Ban Phe Pier — the passenger ferry runs about ฿100–120 per person round trip, with departures throughout the day from morning to evening, and the crossing to Sai Kaew Beach takes around 30–40 min. Private speedboats are faster but cost a lot more.
- Khao Laem Ya–Mu Ko Samet National Park entry fee — ฿40 for Thai adults and ฿20 for children (฿200 for foreigners), collected when you land on the island. Keep your ticket.
- Parking at Ban Phe — private lots around the pier charge roughly ฿60–100 per night, and you can leave your car there while you're on the island.
- Rough distances — Rayong town, Mae Ramphueng Beach, and Ban Phe are all close together, while Laem Mae Phim and Pak Nam Prasae are over in Klaeng district, about 40–50 km from the town center. Grouping those into the last day saves you from backtracking.
- Best time for clear water — roughly November to May, with clear skies and calm seas. Come in May to July and you'll catch durian and Rayong fruit season.
- Cash — on the island and at many small shops, cash is still the main way to pay, so bring small notes.

Day 1 tip
Many cafes around Yom Chinda are old wooden houses converted into shops, so the spaces are small and get busy on weekends. If you want good photo corners, go around midday to early afternoon when it's quieter, and check the opening days of the places you want to visit first — some small shops close early in the week.

Tip on where to stay on the island
For quiet and privacy, choose the Ao Prao or Ao Nuan side, where there are only a few resorts. If you'd rather walk easily to restaurants and a lively beach, stay around Sai Kaew Beach. Room rates on the island rise and fall with the season, so book ahead for long weekends.

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.
Rough budget (per person)
These figures assume two people sharing accommodation and fuel, as a rough frame. Actual prices depend on the season and the level of accommodation you choose.
- Round-trip ferry to Koh Samet ฿100–120
- National park entry (Thai) ฿40
- Parking, 1 night ฿60–100 (split between you)
- Accommodation, 2 nights around ฿1,000–3,000 per person (1 night by Mae Ramphueng Beach + 1 night on Koh Samet)
- Food and cafes, 6–7 meals around ฿900–1,500
- Rough total starting around ฿2,500–5,000 per person, not counting fuel and souvenirs
Can you do it without a car?
Yes, but you'll need to plan the in-province transport. There are vans and buses from Bangkok (Ekkamai) that run straight to Ban Phe Pier in about 3–3.5 hours, and from there you can cross to the island right away. Without a car, though, the Yom Chinda old town and Thung Prong Thong — which are in opposite directions — are harder to reach, and you may need to hire a car or rent a motorbike in town. If you're mainly here for the sea and the island, you can have a great trip without a car, but if you want to cover the old town and the mangrove forest too, having your own car is much more convenient.
The real things to know
During high season and long weekends, the ferries and Sai Kaew Beach get very crowded. To avoid the crush, go on a weekday or take an early-morning ferry, and book your stay ahead. In the rainy season the sea can turn murky with stronger waves; you can still walk Thung Prong Thong, but the wooden boardwalk may be slippery. Always check the weather forecast before you set out.
