Private beach access: what a resort can and cannot control.

The law, in plain terms

Thai beaches are public. The sand below the high water mark is state land, and members of the public may walk it, sit on it and swim from it. A resort with a beachfront concession may place its loungers and umbrellas in a defined area, employ staff to manage that area, and ask non guests to leave its loungers, but it cannot lawfully close the waterline or turn back a Thai family walking along the shore. Enforcement has tightened in both directions over the past decade, with periodic clearances of encroaching structures and periodic reminders to hotels that the public right of passage is real. Any brochure that says private beach is using the phrase loosely.

What a property can genuinely control is everything above the sand: the land, the access paths, the parking, the gate, the security patrol and the setback area where the loungers sit. That control is not trivial. If the only way to reach a bay is through a resort's gate or down a private road with no public parking at the top, then the beach is public in law and empty in practice, which for a family's purposes is what matters. The distinction we insist on when advising is between a right to exclude, which no property has, and a geography that excludes, which some properties have and most do not.

Geography is the whole answer

Phuket's north west coast holds the properties most often booked for this reason. Amanpuri sits on its own headland above a small beach reached in practice through the resort. Trisara occupies a bay of its own on the coast north of Kamala, with a private road down to it. Both are genuinely quiet, and both are quiet because of the shape of the land and the absence of public parking rather than because of any legal right. On the same coast, the Bang Tao and Layan stretch is long, open and easily reached from the road at several points, which makes the beach in front of even an excellent villa there a public thoroughfare in high season.

The pattern generalises. A small bay with one road in and no space to park is private in effect. A long straight beach with a public road running behind it is not, whatever is built on it. Kamala, Surin, Kata and Karon all have public access points and beach vendors. Patong is a town beach and should not be considered at all by a family looking for seclusion. On Samui, the north and west beaches are walkable end to end; the properties with real privacy there tend to be on headlands or in the small coves between the main bays. On Krabi's coast and in the Ao Nang area, the beaches reached only by boat are the private ones, for the obvious reason.

The villa question

Beachfront villas are sold on the promise of stepping from the garden to the sand, and that step is exactly where the privacy stops. In most cases the villa's wall ends at the beach boundary and the sand beyond it is public, so a garden that is perfectly enclosed on three sides opens on the fourth to anyone walking the shore. Some estates solve this with planting, a level change or a low wall that keeps the pool deck out of sight from the beach while leaving the view intact. Many do not, and the photographs will not tell you which is which, because the photographs are taken from the garden looking out.

So the question we ask a villa manager is not whether the beach is private but what is visible from the sand at eye level at low tide. Low tide matters: the beach widens, the walking line moves further out, and the sightline into the garden changes with it. Where a family wants both beachfront and enclosure, the practical answer is often a villa set slightly back with a beach pavilion below it, or a hillside villa with steps down to a cove. Both keep the household life out of view and keep the water two minutes away.

Boats are the real private beach

The most reliably private stretch of sand in Thailand is one you arrive at by water at eight in the morning. From Phuket, Krabi and Koh Yao, a chartered boat reaches a dozen coves and sandbanks that are empty until the day tour fleet arrives around eleven, and a crew briefed properly will hold a beach for a few hours without anyone else setting foot on it. The same is true of the small islands off Samui and Koh Phangan. For families who want the children in open water and the women swimming without an audience, this is the arrangement that works every single time, and it is the one we book most often through the summer.

The mechanics matter. We charter the whole boat rather than a cabin, we brief the crew before the family boards on photography, on where crew are and are not during the day, and on the shaded deck areas being the family's alone. We provision the boat with halal catering loaded from a certified supplier in port rather than relying on what the operator normally serves. We plan the route around tide and wind rather than around the standard itinerary, and in the June to August green season we plan it around the morning, which is calmer on the Andaman side than the afternoon. And we bring the boat back before the sea gets up, rather than after.

Morning, and the shape of a beach day

Even on a busy coast, the hours before ten belong to whoever is awake. Thai beaches fill late; the vendors set up mid morning, the tour boats arrive around eleven, and the sunset crowd is an evening phenomenon. A family that swims at seven and is back in the villa by nine will have had a private beach on a public shore for most of a summer. We build the week around that and put the resort activities, the spa and the shopping into the hours when the sand is busy. It is the cheapest privacy available in Thailand and almost nobody uses it.

What the resort will actually do

• Reserve a fixed set of loungers and an umbrella in a corner of its concession area, away from the main run, for the whole stay.
• Place a beach attendant whose job is to keep vendors and other guests away from your set.
• Set up a private cabana or a shaded pavilion, which most beach resorts have and few guests ask for.
• Move its own photographer, marketing shoots and beach events off your dates or your section.
• Serve food and drink to the beach so nobody in the party crosses a public restaurant terrace in swimwear.
• Provide a covered walkway or a buggy from the villa to the sand so the walk itself is not exposed.

What no resort will do, and none should claim, is remove members of the public from the shore. If a property tells you it can, treat that as a signal about everything else it is telling you. The properties we trust are the ones that explain the concession boundary accurately and then show you what they control inside it.

How we choose, in practice

For a family whose brief includes beach privacy, we shortlist on geography first and amenities second: a bay rather than a strand, one road in, no public parking, a resort or villa estate that occupies the whole frontage. Then we visit at the hour the family will actually use it, which is usually the morning, and count the people. Then we look at the sightline from the water back to the garden, because families think about who walks past and forget about the boat that anchors fifty metres out. A property that passes those three tests is worth paying for. One that fails them is not improved by being expensive.

Beach concession boundaries, access roads and public parking arrangements change, and enforcement of public access rules varies by province and by year. Confirm the current position with the property's general manager and, where it matters, with the local municipality or the provincial office responsible for coastal land before you commit to a long stay.
