Much of what you see today as "Göcek" is actually a town purpose built on a grid plan in late 1980s/early 1990s to boost and serve then newly-emerging tourism in the area, on what was then the coastal plains of the village of Göcek. Up to that date, much of the plains was covered with marshes and some farmland, along with a small port used for exporting logs harvested from surrounding forests for paper-milling and chromium ore, found abundantly and extracted since late 19th century in the surrounding mountains and the reason of many men from surrounding towns—who are now commemorated by a bronze mine worker statue at the town plaza—immigrating to look for a job at a time when, in the absence of tourism, there were little alternative ways of earning livelihood in this hilly region unfit for large agricultural operations.
The "real" village of Göcek, lying about 2-3 km uphill from waterfront and north of main highway, is still extant and retains its village atmosphere to some extent, with freely roaming sheepdogs and roosters here and there, and omnipresent mulberry trees casting their deep shadows much needed in this sunny and hot climate. However, the village itself is now being slowly engulfed by summer villas of urban dwellers from elsewhere.
Nearest airport is located in Dalaman, which receives domestic as well as international flights. From Dalaman Airport, you can take service shuttles run by Havaş  to Fethiye and get off at the junction of Göcek town centre - from there, it's about 10 minutes of walk to the town centre.
Buses heading for Fethiye from major cities of the country pass through Göcek.
D400 connects Göcek north and south. When coming from north (Dalaman, Gökova, Muğla), you may take the tunnel to avoid the very winding and narrow road over the mountain, which is 5 km longer than the route via tunnel. However, this option has a price: Tunnel costs 3 TL/car/one-way and accompanying pessengers won't be able to enjoy the scenery of the mountain road.
There is a car-park at the entrance of the town.
Göcek has three (or more?) yacht marinas, all located in town centre.
Göcek is a very walkable place, with the distance from one end to another not exceeding half an hour's walk.
While the town of Göcek itself has very little to see, its major draw is the coves of the Gulf of Göcek, surrounded by mountains and pine forests rising right from the coastline.
Having said that, though, the beautifully-landscaped and palm lined waterfront promenade can be a sight in itself.
The pleasant Central Mosque (Merkez Camii), just behind the waterfront at the side of town plaza, with its non-traditional red-tile roof and colourful tiles with illustrations relating to Göcek's history and seafaring on its outside fountain, might be worth a check.
Most of the commerce in town takes place in and around Okaliptüs İş Merkezi in the centre of the town. Banks (and their ATMs) are located there, as well as a number of stores offering stuff related to yachting.
Some national and international grocery store chains, such as Carrefour, Migros, Tansaş, and BİM, have stores in the town. Most have free deliveries to the marinas, however, the delivery is usually made by local youngsters with no affiliation to the stores and in the expectation of a tip, so even the smallest tip will be welcome by the delivery boys who receive no salary from the stores.
Many guesthouses can be found around the town, mostly occupying two-storey buildings with little gardens.
Göcek is a very safe place, with local jandarma (Turkish military police responsible for rural safety) officers doing fairly regular patrols along the waterfront, town plaza, and main shopping street. They also have a station in town centre, a block inland from waterfront just on the bank of a creek, where you can file a report should you encounter any problems.
The telephone code of Göcek is (+90) 252.
