Kalymnos: simple holidays with sea and activities

Kalymnos’s strong point is not that everything is cheap. It is that many of the island’s main experiences are simple.

The beaches at Massouri, Myrties, Kantouni, Linaria, Arginonta, Emporios and other coves give you plenty of options for different days by the sea. Pothia adds walks, the local market, museums and the history of sponge diving, while there are paths leading to churches, peaks and archaeological sites.

Food also has a strong local element. Alongside fish and seafood, Kalymnian cuisine includes thyme honey, kopanisti, mizithra, Kalymnian “kalathaki” cheese and spinialo, a distinctive seafood meze linked to the tradition of fishermen and divers.

If you want more activity, you can add it. Climbing, diving and some sea activities require equipment, experience or guidance. But none of these is a prerequisite for the trip to be interesting.

Massouri and Myrties are among the most characteristic summer bases on the western side. Massouri has one of the island’s best-known beaches, and directly opposite lies Telendos, which easily adds a change of scenery to the trip.

Pothia deserves more time than simply arriving at the port. The Maritime Museum presents sponge diving, old diving methods, nautical charts and objects connected with the lives of sponge divers. There is also the Archaeological Museum, while above Chora stands the Great Castle, the old settlement centre of medieval Kalymnos.

Vathy shows a completely different Kalymnos. The fertile valley with citrus trees contrasts sharply with the dry, rocky landscape that dominates most of the island and ends at the narrow bay of Rina.

And if you enjoy walking, there are routes that do not require you to be an experienced mountaineer. The municipality mentions, for example, the route above Kantouni Bay towards Agios Fotios and the old “Italian Path” between Vathy and Pothia.

Religious tradition remains strong on Kalymnos, and Agios Panteleimonas is one of the island’s most important summer celebrations. The monastery celebrates on 26 and 27 July, and the Holy Metropolis reports that Kalymnians and island visitors gather for the feast. The same was the case in 2025 and 2026.

15 August also has a strong presence in local life. On Kalymnos, among other events, the traditional festival of Panagia tou Glykiou has been recorded, with food, music and dancing. Because individual events may change from year to year, it is worth checking the current cultural programme of the municipality before organising your trip around a specific celebration.

There is also a distinctive sporting tradition shortly before 15 August. Every summer, the municipality organises a swimming race from Telendos to Kalymnos, a distance of about one kilometre, with swimmers of different ages and nationalities taking part.

The major event for the climbing community comes later. The International Climbing Festival was held in October 2025, and the municipality has already announced its return in October 2026. This is relevant if your holiday does not have to be limited strictly to the summer months.

May is particularly interesting for the active side of Kalymnos. The average high in the wider area is about 24°C (75°F) and the low around 17°C (63°F). The sea starts becoming part of the trip, while temperatures remain more comfortable for walking, climbing and exploring.

In June, the average high rises to about 28°C (82°F) and the low to 21°C (70°F). It is now clearly a summer month, and you can combine beaches, Telendos, Pothia and activities without yet facing the highest temperatures of July and August.

July has an average high of about 31°C (88°F) and a low of 23°C (73°F), while in August the average high approaches 32°C (90°F) and the low 23°C (73°F) to 24°C (75°F). These are the hottest and driest months, and the programme naturally shifts more towards the sea, evening walks and activities during the cooler parts of the day.

September is one of the months that suits Kalymnos particularly well. The average high remains around 28°C (82°F) and the low around 21°C (70°F). The sea is still a major part of the trip, while conditions also become friendlier for climbing and walking.

Even October remains relatively mild, with an average high of about 24°C (75°F) and a low around 18°C (64°F). It is no longer a classic high-summer month, but on Kalymnos it has particular appeal, especially for those who want climbing, hiking and possible days by the sea without the heat of August.

For Kalymnos, these temperatures come from the nearby Kos Airport station, about 19 kilometres from the port of Kalymnos, and should be read as indicative climatic averages for the area.

Massouri and Myrties are a good base if the group wants to have the sea nearby and add activities depending on the mood. Telendos is directly opposite and can be an easy change for a different day or an evening meal. For a group that loves climbing, the western side is an even more natural choice because of the concentration of climbing sectors.

If the interest is more in local life, Pothia offers a different pace, with a market, museums, the harbour and a stronger everyday character.

For a family, I would place more weight on choosing the right base and beach than on trying to see the entire island.

Panormos and the western side bring together several beaches relatively close to one another, such as Kantouni, Linaria, Myrties and Massouri. This allows you to change beaches without needing a long drive every day.

Kalymnos, however, is not the island I would choose first if a family is looking exclusively for large, shallow sandy resort-style beaches. Here, the overall experience is more about the combination of sea, short transfers, town life and landscape.

Myrties and Massouri offer a very attractive combination of the sea and views towards Telendos. You can spend the day at the beach, cross over to Telendos and on the next day head towards Vathy or Pothia without changing base.

For a couple that wants less “beach all day” and more exploration, Kalymnos has enough content to alternate between the sea, villages, museums, trails and short sea journeys.

Kalymnos has two quite different options.

Pothia is practical if you want to be in the middle of the island’s everyday life and have food, services, museums and municipal transport close by. The municipality notes that basic travel around the island can also be done by municipal buses, so a car is not an absolute requirement for every trip.

Massouri is a more natural base if you want the beach, climbing and contact with other travellers who come to the island for activities. For a solo traveller who wants to take part in organised climbing, the island has instructors and guidance for different levels of experience.

Access needs a little more attention than on some other islands.

According to the Municipality of Kalymnos, you can arrive directly by ferry from Piraeus, fly from Athens to Kalymnos, or travel via Kos. The route via Kos can offer more travel scenarios, but you need to calculate the connection between the flight and the sea transfer to Kalymnos.

On the island, you do not necessarily need a car if you stay in an area that covers your basic needs and use municipal transport. If, however, you want to combine Pothia, Vathy, western beaches, Emporios and different hiking routes, greater freedom of movement will help you make more of the island.

The type of activities you want matters too. The beach, Pothia, several walks and the trails can keep the daily programme simple. Climbing with an instructor, diving or more sea excursions create a different trip and should be included in the cost calculation from the outset.
