Olympic Stadium
Greece is where the Olympic Games began in the 11th century BC, as a festival dedicated to the god Zeus. The first modern Olympics was held in Athens in 1896 in the Panathinaiko Stadium, a 4th century BC stadium which was restored for the games. When Athens won the right to hold the 2004 games, people wondered if the chaotic and polluted city could make it work; they did. The result was a rebuilding program which re-invigorated the city and its transport system.
The Olympic Stadium of 2004 was originally built in the early 1980s for the European Olympic Championships and was remodeled by famous architect Santiago Calatrava for 2004. It seats around 70,000 and is now home to the major Athens football clubs and concerts. The stadium is called Spiros Louis Stadium after the winner of the 1896 marathon.

Bus X14 from Syntagma Square takes about half an hour to reach the stadium. The closest train station is Irini on metro line 1.

Oludeniz and the Blue Lagoon
Beachgoers flock to two separate areas here: a long, wide strip of open beach facing the Mediterranean, known as Belcekız; and the more sheltered shoreline of the Blue Lagoon, which is inside the boundaries of a protected natural park (entrance fee) and has a dramatic backdrop of mountain scenery behind it – Babadağ, one of Turkey’s top destinations for paragliding.
Since Ölüdeniz is extremely popular, be prepared for large crowds on the beaches, particularly on weekends in the height of summer – this isn’t a place for those seeking peace and quiet – and for the inevitable slew of generic restaurants and tacky souvenir shops along the waterfront.
As if the lagoon weren’t entrancing enough, there are also daylong boat trips that leave from here for scenic coves and beaches nearby, as well as to points of interest including Butterfly Valley. In addition, Ölüdeniz is the starting point for the Lycian Way, a 510-km (315-mile) hiking trail that runs from Fethiye to Antalya along the coast.
Practical Info
The natural park is open from 8am to 8pm and admission is 4.5 TL.
