The town is located on the flat alluvial land called Bödeli between the two Lakes of Brienz to the east and Thun to the west and alongside the river Aare, which flows from one to the other. Transport routes to the east and west alongside the lakes are complemented by a route southwards into the near mountain resorts and high mountains, e.g. the famous high Alpine peaks of Eiger, Mönch, and Jungfrau, following upwards the Lütschine.
Interlaken is the central town of a Small Agglomeration with the same name of 23,300 inhabitants.
The official language of Interlaken is German, but the main spoken language is the local variant of the Alemannic Swiss German dialect.
Until 1891, Interlaken was known as Aarmühle. The convent of the Augustinian Canons was built around 1133 when it was mentioned as inter lacus Madon and lasted until 1528. The mill on the left bank of the Aare was first mentioned in 1365 as Amuli, while the town on the right bank was mentioned in 1239 as villa Inderlappen.
Previously, printing, textiles, and to a smaller extent watchmaking were also of importance, but today tourism is the most significant source of income. Interlaken is one of the oldest tourist resorts in Switzerland, and it remains one of the most popular.
While some scattered Neolithic flint objects, early Bronze Age swords and Roman era coins have been found near Interlaken, there is no evidence for a settlement in the area before the Middle Ages. Interlaken Monastery was built around 1133 on imperial land on the left side of the Aare. The monastery controlled a bridge over the river and generated an income from tolls. A village grew up around the monastery, along with a mill (which gave the municipality its name until 1891). On the right bank of the river, Interlaken village developed. In 1279/80 the village of Unterseen developed near Interlaken village. Also near the village were the imperial castle of Weissenau and the market town of Widen. The castle and market town became the possessions of the monastery, but fell into disrepair in the Late Middle Ages.
The Interlaken Monastery was first mentioned in 1133 when Lothair III, Holy Roman Emperor took it under his protection. By 1247, there were also women at the monastery. During the 13th century the monastery's influence spread throughout the neighboring area and into the Aare and Gürbe valleys. They eventually had authority over two dozen churches along with a number of villages and farms and became the largest religious landholder in the region.
During the 13th and the beginning of the 14th century the monastery grew and prospered. However, in 1350 a period of crises and conflicts led to a decline in the number of monks and nuns and increasing debt. A document from 1310, indicates that there were 30 priests, 20 lay brothers and 350 women at the monastery. In contrast, in 1472 there were only the provost, the prior, nine ordinary canons, seven novices and 27 nuns. At this time, the monastery also had problems with its tenants and neighbors. In 1348, the people of Grindelwald and Wilderswil joined a mutual defense league with Unterwalden. Bern responded with a military expedition to the Bernese Oberland, which ended in defeat for Unterwalden and its allies. In 1445 the Evil League (Böser Bund) rose up in the Oberland near Interlaken and fought against Bernese military service and taxes following the Old Zürich War.
During the 14th century the canons and nuns stopped following most of the monastic rules. In 1472 a violent dispute between the men and the women's convents resulted in two visitation by the Bishop of Lausanne who noted serious deficiencies. The provost was arrested and some of the canons were replaced by canons from other convents. Despite the reform measures the nun's convent was closed in 1484 and its property transferred to the newly founded monastery of St. Vincent in Berne.
During the Protestant Reformation, the monastery was secularized in 1528. The canons received a financial settlement and the properties were now managed by a Bernese bailiff. The tenants of the monastery who had expected the abolition of all owed interest, responded by rioting, which was suppressed by Berne.
After the Reformation, Berne created the Interlaken bailiwick from the monastery lands. Part of the monastery building was used as the headquarters of the district administration, while the rest was used as an indigent hospital. In 1562-63 Berne converted the monastery church's choir into a granary and a wine cellar. In 1746-50 the west wing was demolished and Governor Samuel Tillier built the so-called New Castle. It has remained the center of administration for the Interlaken district since that time.
Aarmühle was named for the mill on the Aare which was built there in or before 1365. Starting in 1365, the monastery held weekly and yearly markets at Aarmühle. It had its own bäuert (agricultural cooperative) but was politically part of the municipality of Matten.
In the 16th century the bäuert of Aarmühle and the surrounding bäuerten began quarreling over the use of common fields and woods. Attempts at arbitration in 1533, 1586 and 1618 were unsuccessful. Partly as a result of the quarreling, in 1633, Wilderswil separated from Matten and became an independent municipality. However, the dispute continued between Aarmühle and Matten and in 1761, the governor of the Interlaken district attempted, unsuccessfully, to mediate. Finally, in 1810 the two villages divided their common property, though it took until 1838 for Aarmühle to become an independent political municipality.
Around the time of the separation, the number of tenant farmers (farmers that did not own the land that they worked) was very different in Aarmühle and Matten. In 1831, 37% of the population in Aarmühle were tenants, while only 12% were in Matten. This meant that the population of Matten were closely tied to the land and remained farmers, while in Aarmühle they began to support the growing tourism trade.
On the right bank of the Aare, Unterseen became the only municipality and absorbed the village of Interlaken. In 1838, on the left bank, the villages became the two municipalities of Matten and Aarmühle. However, Aarmühle used the name Interlaken for its post office and train station, leading to that name becoming more well known. Officially the name changed to Interlaken in 1891.
Interlaken's reputation as international resort started around 1800 due to the landscapes of Franz Niklaus König and other Swiss landscape artists. The success of the Unspunnenfest, a festival of Swiss culture, in 1805 and 1808 brought many tourists to Interlaken. Starting in 1820, they came for mountain air and spa treatment and the large Kursaal opened in 1859 to provide an elegant spa. The many hotels combined with good transportation links made it easy for these early tourists to visit. In 1835 a steam ship route opened along Lake Thun from Thun, followed in 1839 by another along Lake Brienz from Brienz.
In 1872, the Bödelibahn railway opened from Därligen, on Lake Thun, to Interlaken. Two years later it was extended to Bönigen, on Lake Brienz. Initially this line was unconnected to the rest of the Swiss railway system, and served as a link between the steamships on both lakes. However, in 1893, the Thunersee railway opened alongside Lake Thun providing a direct rail connection to Thun, with onward connections to Bern and beyond. In 1888, the Brünig railway opened between Alpnachstad, on Lake Lucerne, and Brienz, on Lake Brienz, thus providing a through steamer and rail connection from Interlaken to Lucerne. By 1916, the Brünig railway had reached Interlaken from Brienz, and, together with an earlier extension at its eastern end, provided a direct rail route to Lucerne. In 1890, the Berner Oberland railway connected Interlaken to the tourist destinations of Lauterbrunnen and Grindelwald.
With the opening up of transport links, hotels developed along the route to the Jungfrau. In 1860-75 and 1890-1914 several luxury hotels were built with views of the Jungfrau and surrounding mountains. The current Kursaal was built in 1898-99 and remodeled in 1909-10.
Despite the emphasis on tourism a parquet factory operated from 1850 until 1935 and a wool weaving factory opened in 1921. In the late 20th century a woolen thread and a metal products factory opened in Interlaken. Since 1988, Interlaken has been connected to the A8 motorway.
The frantic growth of the tourism industry abruptly ended in 1914 when World War I started, though it resumed somewhat after the war. World War II brought another dramatic slow down. Interlaken started to recover from the effects of the war in 1955 as Interlaken re-branded itself as a convention and conference center. Today, the two nuclei villages (Aarmühle and the village around the Bailiff's Castle) have been joined by new construction between them. The municipalities of Matten and Unterseen are also connected by new construction to Interlaken and share a common infrastructure. A referendum to merge the three political municipalities into one was voted down in 1914 and again in 1927.
Interlaken is located at 566 m (1,857 ft) above sea level, between Lake Brienz to the east and Lake Thun to the west on the alluvial land called Bödeli. The town takes its name from its geographical position between the lakes (in Latin inter lacus). The Aare flows through the town from one to the other lake, whilst the Lütschine flows from the mountains from the south into Lake Brienz however not running through the municipality of Interlaken.

Whilst the peaks of these mountains are accessible only to mountaineers, a sequence of connecting mountain railways gives access to the Jungfraujoch, a saddle (3,454 m (11,332 ft)) between the Jungfrau and the Mönch, but correctly translated as a yoke (German: Joch), which is the highest point in Europe reachable by train.
Closer to Interlaken, the Harderkulm (1,321 m (4,334 ft)), just to the north of the town, and the Schynige Platte (1,967 m (6,453 ft)), just to the south, are also accessible by railway, and provide extensive views of the higher mountains. Lake Thun and Lake Brienz are both close to the town, and the Aare flows east to west through the town. Boat trips operate on both lakes, serving various lakeside towns. One of these, Brienz, is the starting point for one of Switzerland's last remaining steam operated mountain railway, the Brienz-Rothorn railway.
Jungfrau Park, an amusement park, is situated just to the south of Interlaken. It was originally opened as a Mystery Park, a paranormal-based theme park owned by author Erich von Däniken, but was closed in 2006 after three years because of financial difficulties. It re-opened in its current guise in 2009.
Interlaken has a large selection of hotels of various grades, many of which are located along the Höheweg, a street that links the towns two railway stations and offers views of the mountains. Other hotels are clustered around one or other of the two stations, or located across the river in the neighbouring municipality of Unterseen.
Interlaken is also a destination for backpackers. It has numerous backpacker-friendly hotels and companies providing guided services in skydiving, canyoning, hang gliding, paragliding, and skiing.

Interlaken has two railway stations, Interlaken Ost and Interlaken West, which are both served by the BLS AG's Thunersee line that provides direct services to Spiez, Thun, Bern and beyond, with onward connections at Bern to the rest of Switzerland. Through international services are provided by TGV to Paris and ICE to Frankfurt and Berlin.
Besides being the terminal of the Thunersee line, Interlaken Ost is also the terminus of the Zentralbahn's Brünig line to Brienz, Meiringen and Luzern, with onward connections to north-eastern Switzerland. The Berner Oberland railway also operates from Ost station, providing the first stage of several mountain railway routes into the Jungfrau region and, most notably, to Europe's highest station at the Jungfraujoch.
Boat services across Lake Brienz to Brienz and across Lake Thun to Spiez and Thun are operated by the BLS AG. The boats on Lake Thun operate from a quay adjacent to the West station, connected to Lake Thun by the Interlaken ship canal. The boats on Lake Brienz operate from a quay on the Aare by the Ost station. The remainder of the Aare between the two lakes is controlled by several weirs and is not navigable.
Interlaken is connected by the A8 motorway to Thun and Lucerne, with onward connections by other Swiss motorways to the rest of Switzerland. Local roads also follow both banks of the lakes to east and west, and follow the valley of the Lütschine south into the Jungfrau region. However it should be noted that there is no direct road connection across the mountains of that region into the canton of Valais to the south, with the nearest such connections being the Grimsel Pass to the east, or using the vehicle transport service through the Lötschberg rail tunnel to the west.
In the more immediate area, two funicular railways, the Harderbahn and the Heimwehfluhbahn, provide service to nearby vantage points. Local and regional bus services are provided by PostBus Switzerland, whilst Verkehrsbetriebe STI operates a regional bus service to Thun.
The former Monastery Building, the Hotel Royal-St. Georges, the Hotel Victoria-Jungfrau and the Kursaal are listed as Swiss heritage site of national significance. The entire urbanized village of Interlaken is part of the Inventory of Swiss Heritage Sites.
