Skopelos is a Greek island in the western Aegean sea. Skopelos is the largest of several islands which comprise the Northern Sporades island group. The island is located east of mainland Greece, northeast of the island of Euboea and is part of the Prefecture of Magnessias in the Peripheria of Thessalia. Skopelos is also the name of the main port and the municipal center of the island. The other communities of the island are Glossa and Neo Klima (Elios). The geography of Skopelos includes two mountains over 500 meters; Delfi (681 m) in the center of the island, and Palouki (545 m) in the southeast. With an area of 96 km² (36.5 mi²) Skopelos is slightly larger than Mykonos (85 km²) and Santorini (73 km²). The nearest inhabited islands are Skiathos to the west and Alonissos to the east.
Skopelos has the shape of a saxophone, with the "neck" pointing northwest, and the "bell lying on the east. There are not many beaches and natural harbors, and cliffs steeply fall into the sea in the greatest part of the coast. Mountains dominate the western and eastern parts of the island. There are several plains; in Staphilos, Dytropon, and Panormos. The main port of Skopelos can sometimes be closed due to northerly gales. The smaller bays of Staphilos, Agnondas on the south coast and Panormos on the west offer better protection.

The main port and municipal center of the island (Skopelos or "Hora") is situated in the bay on the northern coast. It is noted for its architectural heritage. On the census of 2001, it had 3,027 inhabitants.
The second largest settlement is Glossa village, situated on the northwestern tip of the island, just above Loutraki harbour, with an elevation ranging from 200 to 300m. It is 25,4 km from Skopelos town. It is a tranquil village with traditional houses, with 1,195 residents.
Neo Klima or "Elios" is a purpose-built village constructed after the great 1965 earthquake to resettle the displaced residents of the severely damaged village of (Old) Klima. It is situated by the coast on the west side of the island. The village had 415 inhabitants in the 2001 census.
Other settlements include Stafilos, Agnodas, Panormos, Ananias, Klima, Atheato, Loutraki, Kalogeros, and Mili.
The length of the coastline of Skopelos is 67 km. Due to the island's mountainous terrain most of the coast is inaccessible. The following are beaches accessible by road or trail: Staphylos, Velanio (the unofficial nudism beach), Agnondas, Limnonari, Panormos, Adrines, Milia, Kastani, Elios, Hovolo, Armenopetra, Kalives, Glyfoneri, Glysteri, Perivoliou, Keramoto, Hondrogiorgos.

As "The Green and Blue Island", Skopelos lags behind urban Greece in rubbish recycling and sewage treatment. Currently there is no rubbish recycling program in Skopelos. Solid and hazardous waste is deposited in a landfill or dumped unofficially on untended public or private land. Periodically families of Roma people come to Skopelos to collect scrap metal from areas around the island where trash has been illegally dumped. The scrap metal is removed from the island by lorry and sold on the mainland. Beer and bulk wine bottles are recycled by the distributors. There is a deposit collected for each bottle at time of purchase which is redeemed upon return.
Over the past 30 years residents have begun to use solar collectors for hot water. With about 2400 hours of sunlight per year Skopelos has the potential to increase its use solar energy use and to develop alternative sources for energy which make use of a frequent and steady northerly wind. Major construction and mass tourism development projects for hotels and tourist housing have not yet embraced the concept of alternative resources. Most recently built projects rely on electricity generated on the mainland, even for hot water. The projected demand for electricity in Skopelos has caused problems in Skiathos. The Public Power Corporation had plans to run a new line to Skopelos from the mainland under the sea to Skiathos, then overland via electricity pylons and back under the sea to Skopelos. Residents of Skiathos organized a protest to stop the project and the matter now is in the hands of the Greek judicial system.

The island is served by commuter hydrofoils and ferry boats from the ports of Volos Magnessia and Agios Konstantino, Fthiotis on mainland Greece which also allows connections to and from Alonissos and Skiathos. In summer there is a ferry to and from Thessalonica and Kymi in Euboea. Skopelos has one main road which links the three main villages by coach several times daily. In the mid 1980s the Mayor's Council voted to apply to the Ministry of the Interior for the construction of an airport. The application was denied. There is a heliport in case of medical emergencies.
