101 Ultimate Guide to Rock Climbing at Kalymnos Island

Beginner Guide to Rock Climbing at Kalymnos Island Greece

To the untrained eye, Kalymnos is just like any other Greek island – turquoise waters, giant limestone cliffs, and little Greek villages crumbling under the strain of time, however, since 1995, it has been capturing the attention and hearts of the climbing community. Aided by several international climbing festivals and a strong infrastructure, the Kalymnos climbing community has grown and developed the island into a world-renowned climbing destination in Europe, known for an abundance of sports routes across a wide range of grades set against a gorgeous Aegean backdrop. Having been there twice already and its one of my favourite climbing spots in the world, lets dive into whats so great about rock climbing at Kalymnos.

About Kalymnos Island

Kalymnos built a large portion of its economy on sponge fishing, but due to a viral disease in 1986, this industry has suffered and largely collapsed. These days, the island’s income largely comes from tourism. The majority of visitors flock to neighboring islands, and so visitors to Kalymnos can expect a more environmentally conscious crowd and a more local and authentic atmosphere. Visitors of Kalymnos are mostly interested in exploring the natural surroundings, climbing, hiking, and visiting the coast.

Where is Kalymnos in Greece

Kalymnos is a small island in the Icarian Sea, just a stone’s throw away from the Turkish coast. It can be found right in the Southeast corner of the Greek archipelago, as part of the Dodecanese islands, and situated between the islands of Leros and Kos. As with most of the islands in the Aegean Sea, it is officially part of the country of Greece and the official language is Greek, although most touristic establishments also possess some grasp of the English language.

The climbing background of Kalymnos

Like much of Greece, there are giant limestone cliffs everywhere on the island of Kalymnos. After the Italian climber Andrea di Bari visited the island in 1996 and saw the potential of the quality limestone, he began to establish a climbing scene by opening 43 sports routes in 1997. Since then, the climbing scene has quickly expanded and developed into a world-class sports climbing destination that attracts both casual climbers and professionals alike.

There are no multi-day routes, official bouldering areas, or trad climbing routes established on the island. That being said, there are a large variety of routes, from technical slabs to pocketed overhangs, at a range of different difficulties, so there is something that every climber from every background should enjoy. Here’s going into greater detail of outdoor rock climbing at Kalymnos this summer.

Sport Climbing

Kalymnos is home to more than 3400 sport climbing routes, an impressive amount for a small island. Most of the routes are easily accessible with only a short hike to the base of the crag. 

The routes are graded using the French grading system, and routes have been graded from 5a to 9a (5.7 – 5.14d on the Yosemite scale), so climbing can be enjoyed by both beginners and experts alike. The average route is roughly 30m in height and completed in a single pitch. There is no standard character for climbing routes as there are so many available, but some common themes are as follows:

  • Very steep overhangs, complete with stalactites 
  • Gently overhanging or vertical pocketed routes 
  • Smooth slab routes with sharp holds

As most routes are single pitch sport routes, the standard sports equipment rack is all you will need to get started, although some routes on stalactites require some additional slings to reduce rope friction. The infrastructure is strong in Kalymnos, and routes are frequently re-bolted to ensure maximum safety.


In more recent years, the climbing community of Kalymnos has opened some longer routes, some of which require more than a single pitch to complete. While this is not the standard for climbing in Kalymnos, it is worth noting that it is possible, and if you intend to try some of the multi-pitch routes, to bring sufficient equipment to protect yourself. These can range from 2 or 3 pitches, right up to the 11 pitch route “Eterna” found on the South face of Telendos. 

Climbing Grades at Kalymnos island

Kalymnos prides itself on having routes that are attractive to climbers of all abilities and styles, whether they are transitioning from indoor to outdoor climbing, taking an easy climbing vacation, absolute beginners, or are climbing professionals looking to add to their repertoire of red-pointed 9as.

Routes are graded using the French system. Often you can find the difficulty of the route painted at the base of the route, however, gradings are frequently re-considered, and in order to keep consistent grading across the island, it is normal that grades are updated and these painted route numbers are inaccurate. 

Best Climbing Routes on Kalymnos island

  • Tufa King Pumped (7B+) – As the name suggests, this is a long and pumpy pocketed climb. 
  • Chnosi Family (7A) – A technical slab piece with difficult balance transitions and a high traverse to test out your footwork on. 
  • Dionysos (7A) – A pumpy route with many jugs and several good rest points, but also with a difficult finish. 
  • Los Revolucionarios at Odyseey (9A) – considered the hardest climb on the island, redpointed by both Megos and Ondra. 
  • 3 Stripes (5C) – An easy but adventurous multi-pitch route consisting of six pitches of stainless-steel bolted slabs. 

Best time of the year to climb at Kalymnos island

As the climate on the island is fairly stable, it is possible to climb throughout the entire year, however, the routes that you choose should be reflective of the season. 


Greek summers are warm, and so rock climbers will naturally flock to the shaded routes, as climbing in the direct sunlight will quickly lead to potentially dangerous dehydration. If you intend to spend the entire day climbing in summer, be sure to pack a couple of long-sleeved jackets, as the ocean breeze can be cooler than you anticipate when you are belaying. 

Best time of the year to climb at Kalymnos island


Kalymnos is blessed with a mild and sunny winter, perfect for climbing on sunnier routes, however tourism in the entire region tends to shut down over the winter months, and accessing the island becomes more difficult, accommodation becomes sparser, and restaurants often close, all of which can be problematic and are worth factoring in your planning. 


Autumn is the ideal time for climbing, provided you don’t mind following the crowds. Days are long, warm, and dry, and the sea is warm enough for swimming. October is the peak climbing month for this reason, which some will see as a good way to experience ideal conditions and connect with the climbing community, but others will consider it a burden due to potential crowds. 


Spring is also an ideal time for climbing, however, the possibility of rain is slightly higher, and many consider the sea a little too cold for a post-climbing cool-down. You might want to try some cave climbing spring the spring, but do be aware that the rainwater can still seep its way inside and soften the rock.
