Sand Dunes Chaolao Beach Resort — a beachfront resort on Chao Lao Beach with its own mini train
Picture walking a few steps from your room to a pool that looks out over the long sweep of Chao Lao Beach, while a little mini train trundles guests between the lobby and the pool zone to the kids' delight — Sand Dunes Chaolao Beach Resort is the 4-star beachfront pick many families choose for a seaside escape on Thailand's eastern coast. 185 sea-view and garden-view rooms, a beach restaurant, a kids club and plenty of children's activities. Rooms start from approx. THB 2,200/night.
Chao Lao Beach is a long stretch of sand in Tha Mai district, about 30 minutes from central Chanthaburi — quieter than Pattaya, less crowded than Rayong, and still close enough that Bangkok families can drive down for a day or a weekend. Sand Dunes Chaolao sits right on the beach, so you can walk from your room straight onto the sand without crossing a road — the point reviews mention most often when comparing it to other resorts along the same stretch.
The resort has 185 rooms across 14 types, from the 31 sqm Superior up to the 46 sqm Deluxe Corner and Pool Access rooms you can step into the pool from. Almost every room has a private balcony, and many face the sea directly, while the cheaper rooms look onto the garden or pool. Guests describe the rooms as spacious, clean and comfortable, with Family and Triple options that suit larger groups travelling together.
"The kids were thrilled by the little train running around the resort — they rode it in loops all day, and we loved that it's only a short walk from the room to the pool."
The feature children love most is the Bunny Train, a mini train that shuttles between the lobby, the pool zone and the beach, alongside a kids club, the Wonder Art Zone and bicycles to borrow for a ride along the shore. The large outdoor pool faces the sea, and many guests call it an infinity-edge pool because the water seems to merge with the ocean — sunset is when most people gather to take photos.
On food, there are two main venues, Rice Berry and The Shore on the beach. The breakfast buffet draws plenty of praise, with Thai, Western and dim sum options that are varied and tasty. The beachside restaurant has a lovely atmosphere in the evening, dining to the sound of the waves. Service — from the front desk and bellboys to the restaurant team — is another point reviews agree on, described as attentive, warm and friendly.
To be honest, the thing to accept is that Chao Lao Beach itself isn't pristine year-round. Some reviews note that the public beach outside the resort grounds collects seasonal litter, especially after the monsoon, and the sea here isn't as clear as the Andaman side. Within the resort, cleanliness is well maintained. A few guests also mention sound carrying between rooms, weak water pressure in some rooms and pool water quality that's only fair on some days — small details worth knowing before you go.
Overall, Sand Dunes Chaolao is a sensible pick for families and groups who want a beachfront resort close to Bangkok at a fair price. Its 9.0 from real reviews and top ranking among Chanthaburi's 4-star hotels come not from luxury but from the beachfront location, the breadth of children's activities, the good service and the value. If you expect island-clear water you'll need to adjust expectations, but if you want a seaside stay where kids have fun and adults relax on a manageable budget, it does that well.
A tip from reading the reviews here: choose a direct sea-view room on a higher floor for the fullest view and a little distance from pool noise. Travelling with small children, book a room near the mini-train stop for convenience. Over long weekends and Saturdays prices rise quickly and rooms fill fast, so book ahead and compare a few platforms before you commit.

- 💡If you expect island-clear Andaman water — Chao Lao is an eastern-coast beach, with greener, cloudier water → adjust expectations on water colour, but gain a quiet beach close to Bangkok.
- 💡If you're a couple wanting peace and quiet — this place leans toward families and children, and it gets lively and loud over holidays → choose a high-floor room away from the pool, or avoid long weekends.
- 💡If you go just after the monsoon — the public beach can collect seasonal litter → check the weather and timing before booking. Within the resort, cleanliness is well kept.
