Although the island is barren and rocky, with only a small plain, it is very important in terms of its ecosystem.
The entire island of Telendros has joined the community network of protected areas "NATURA 2000" and is an Important Area for the birds of Greece.
Because the northern part of the island is uninhabited, it is an ideal refuge for rare species of seabirds such as the egret, so that they can nest undisturbed.
In addition, the island's only settlement, currently inhabited by 25-30 souls, has been characterized as traditional.
Right next to Kalymnos, just 900 meters from its shores, Telendos invites you for a day trip, to enjoy a peaceful atmosphere and swim in its deep blue shores. You can easily get there from Kalymnos, which is connected by boats that depart from Myrties and make regular routes.
The island has to show, despite its small size, several remarkable beaches.
Almost all are accessible by land, some can be reached by foot, but it's worth the effort because you'll be rewarded if seclusion is what you're looking for.
Be sure to bring everything you will need, because the following beaches are deserted in every sense of the word.
Drowned: Sandy beach with quiet. It is located SW of the early Christian necropolis under a small gorge, Rafi.
Chochlakas: It is located under St. Triada - pebble and fine gravel with crystal clear waters.
Potha- 10' walk north of the port. This beach is equipped with sunbeds.
Paradise: Paradise is essentially an extension of Potha Beach. It is a nudist beach with sand and fine pebbles on the shore.
If you have come with your boat, the island is ideal for sailing and coastal exploration. There is little possibility of mooring in the port, but keep in mind that refueling will be done from Kalymnos.
If walking fascinates you even on your vacation, Telendos offers two short routes so you can get to know it better.
We suggest you visit the ruins of the impressive early Christian church of Agios Konstantinos, built in the 7th century. From the port of Telendos, following the well-formed path to the north parallel to the sea, you will find signage directing you to the church (approx. 1 hour from the port). After your visit, walking 20 minutes, you can head to the beach below the monastery and enjoy swimming in its crystal clear waters.
There is also the possibility of renting a boat that will take you to the port below the church and the castle. From there you proceed along the path (20 minutes), to the ruins and return by the same route (having an appointment with the boat) or by the first one we suggested, ending up at the port of the settlement.
Also interesting is the hiking route that we suggest you do to the Early Christian Necropolis - Follow the dirt path that starts to the left of the port, pass through the pine forest and at Tholaria you will get to know the Early Christian Necropolis of Telendos, one of its most important archaeological monuments island.
Nine burial buildings are preserved in the form of vaulted buildings (from their form the area got its name -Tholaria-), on their floor there are built rectangular tombs.
Next, SW of the early Christian necropolis under a small canyon, Rafi, you can go for a swim in Pnigmenos cove, where the ruins of an arched early Christian temple are also preserved.
