The verdict

Best for. Confident swimmers and walkers who want a wild, quiet south coast beach with dramatic cliffs and a swim through arch, and who are happy to arrive by boat or earn it on foot.

Best spot. The clear water around the natural arch on a calm day, reached most easily by a south coast boat trip that often pairs Gerontas with Kleftiko.

Know this. This is a remote, unorganised beach with no facilities and a rough approach, so it is not a family day. For sand, shade and a short walk with children, choose Provatas or Firiplaka.

Sand
Dark sand and rock
A small beach of darker sand below pale cliffs on the wild Chalakas coast, with a natural rock arch in the sea just offshore and clear deep water around it.
Water
Clear, deep, open coast
Beautifully clear water that is deep around the arch rather than shallow, lovely for confident swimmers on a calm day but exposed when the south wind blows.
Entry
Free, hard to reach
Free, but reached by boat or by a rough dirt road, a ten to fifteen minute walk and a ladder down, so the descent is not suited to small children.
Facilities
None at all
Completely unorganised like the rest of Chalakas, with no sunbeds, bar, toilets or shade, so bring everything you need and carry all your rubbish out.
Lifeguard
None, to be confirmed
No lifeguard and deep open water around the arch, so this beach suits strong swimmers on a settled sea and is not a place for a careful toddler paddle.
Best months
June, September
Calmer seas for the boat and the arch swim, with softer light on the cliffs and far less chance of the summer wind that churns this exposed coast in peak season.
The honest read

Gerontas is one of the wild ones, a small beach tucked under pale cliffs on the remote Chalakas coast at the southwest end of Milos, with dark sand and a natural rock arch standing in the clear sea just offshore. Confident swimmers slip out and swim through the arch on a calm day, and the seclusion is the reward, since this is a quiet, unspoilt corner far from the organised beaches. For a strong swimmer who loves a beach earned rather than driven to, it is a memorable few hours.

The honest read, and the one a family needs to hear, is that Gerontas takes real effort and gives nothing back in the way of comfort. There are no facilities at all, no sunbeds, no bar, no toilets and no shade, so you carry in everything and carry out your rubbish. By land you drive to the end of a rough dirt road, walk ten to fifteen minutes and climb down a ladder to the sand, which is no place for a pushchair or a toddler. The water around the arch is deep rather than shallow, and the open south coast can turn rough quickly when the wind gets up.

So Gerontas is a beach to choose on purpose, not a default family day. The gentlest way to see it is by boat, since many south coast trips pair it with Kleftiko, which spares you the road and the ladder and gives you the best of the cliffs from the water. Bring plenty of water and sun cover, come on a calm morning, and treat it as an adventure for confident swimmers. When you want sand underfoot, shade and a short walk with children, the organised south coast beaches at Provatas and Firiplaka are the easy choice. Conditions here are typical and never guaranteed, so judge the sea for yourself.

The club layer

Wild and unorganised, so book elsewhere

Gerontas has no clubs, sunbeds or facilities of any kind, so there is nothing to book on the beach. The easiest way to enjoy it is a south coast boat trip that pairs it with Kleftiko. For an organised day with children, the sandy beaches and sunbeds are elsewhere. We list what is genuinely there and mark the rest to be confirmed. See the Milos beach clubs guide for the full run.

A boat trip, then an organised beach

There is no beach club or concession at Gerontas, only the wild beach and the sea arch, so plan your organised day elsewhere. The easiest way to reach Gerontas is a south coast boat trip that often combines it with Kleftiko, while the closest sunbeds, shade and shallow water for children are on the south coast at Provatas, Firiplaka and Agia Kyriaki. Operators, timings and prices are set by the companies and are to be confirmed by season.

On the wild Chalakas coast near Kleftiko

Gerontas lies on the remote Chalakas coast at the southwest end of Milos, near the famous sea caves of Kleftiko. The gentlest way to reach it is by boat, since many south coast trips combine Gerontas and Kleftiko in one outing and save you the land approach. By car you drive to the end of a rough dirt road, then walk about ten to fifteen minutes and climb down a ladder to the beach, which is not suited to small children.

There are no facilities here at all, so bring plenty of water, food, sun cover and a hat, and carry out everything you bring in. The open coast can turn rough when the south wind blows, so come on a calm morning for the boat and the swim through the arch, and leave the deep water to confident swimmers. For an easy day with sand, shade and a short walk, the organised south coast beaches at Provatas and Firiplaka are the simpler choice.

Common questions about Gerontas

Is Gerontas good for families with young children?

Not really. Gerontas is a remote, unorganised beach on the wild Chalakas coast, reached by boat or a rough walk and a ladder from the dirt road, with no facilities at all. The setting and the swim through arch are wonderful for confident swimmers, but the access and the lack of shade, water or toilets make it hard work with toddlers. Families are far better served by the organised sandy beaches at Provatas and Firiplaka.

How do you get to Gerontas beach?

Most people reach Gerontas by boat as part of a south coast trip that also visits Kleftiko, which is the easiest and most scenic way. By land you drive to the end of a rough dirt road and then walk about ten to fifteen minutes, with a ladder down to the beach at the bottom. The drive and the descent are not suited to small children, so the boat is the gentler option.

What is the arch at Gerontas?

Gerontas is known for a natural rock arch in the sea just off the beach, with a pale rock below and a darker rock above, that confident swimmers can swim through on a calm day. It is one of the more memorable swims on the south coast. The water is clear and deep around it, so it suits strong swimmers rather than paddlers, and only when the sea is settled.

Are there facilities at Gerontas?

No. Gerontas is completely unorganised, like the rest of the Chalakas coast, with no sunbeds, no bar, no toilets and no shade. Bring everything you need, including plenty of water, sun cover and food, and take all your rubbish away with you. There is no lifeguard, so judge the sea and your own swimming for yourself, especially around the arch.

Is Gerontas worth the effort?

For the right traveller, yes. If you want a wild, quiet south coast beach with dramatic cliffs and a swim through arch, and you are happy to arrive by boat or to walk the rough path, Gerontas rewards the effort with seclusion and beautiful water. If you want an easy day with sunbeds, shade and a short walk, it is not the beach for you, and the organised south coast beaches are a better fit.
