Tombolo in the context of "Isthmus"

Gugh (/ɡjuː/ GHEW; Cornish: Keow, lit. 'hedge banks') could be described as the sixth inhabited island of the Isles of Scilly, but is usually included with St Agnes with which it is joined by a sandy tombolo known as "The Bar" when exposed at low tide. The island is only about 1 km (0.62 mi) long and about 0.5 km (0.31 mi) wide, with the highest point, Kittern Hill, at 34 m (112 ft). The geology consists of Hercynian granite with shallow podzolic soils on the higher ground and deeper sandy soils on the lower ground. The former Gugh farm is just north of the neck across the middle of the island between the two hills. The two houses were designed and built in the 1920s by Charles Hamlet Cooper.

The island lies within the Isles of Scilly Heritage Coast, is in the Isles of Scilly Area of Outstanding Natural Beauty and is managed by the Isles of Scilly Wildlife Trust. Vegetation cover is mainly wind-pruned heath or dense bracken and bramble with a small area of coastal grassland formed over blown sand which has accumulated near the bar.

Miquelon-Langlade (French pronunciation: [miklɔ̃ lɑ̃ɡlad]) is the larger but less populated of the two communes (municipalities) making up the French overseas collectivity of Saint Pierre and Miquelon, located 22 km (14 mi) to the south of Newfoundland in the Gulf of St. Lawrence. It consists of three islands: Miquelon (also called Grande Miquelon), Langlade (Petite Miquelon) and Le Cap, connected by narrow tombolos (sandy isthmi). The communal seat is the settlement of Miquelon, on the northern tip, where the entire island's permanent population of 596 (as of 2022) is located. Miquelon Airport provides flights to nearby Saint-Pierre Airport.

Monemvasia (Greek: Μονεμβασιά, Μονεμβασία, or Μονεμβάσια) is a town and municipality in Laconia, Greece. The town is located in mainland Greece on a tied island off the east coast of the Peloponnese, surrounded by the Myrtoan Sea. Monemvasia is connected to the rest of the mainland by a tombolo (sandy isthmus) 400 metres (1,300 ft) in length.

In 1890, a small part of the natural tombolo was cut to create an artificial bridge for ships and boats. Its area consists mostly of a large plateau some 100 m (330 ft) above sea level, up to 300 m (980 ft) wide and 1 kilometre (0.62 mi) long.

Paraguaná (Spanish pronunciation: [paɾaɣwaˈna]) is a peninsula and tied island in Venezuela, situated in the north of Falcón State, and comprises the municipalities of Carirubana, Los Taques and Falcón. The island of Aruba lies 27 km (17 miles) to the north. Bonaire and Curaçao are slightly further away. Paraguaná lies in the Caribbean Sea, and is connected to the rest of the state by the natural isthmus or tombolo of Médanos.

Gatas, or more commonly Isla de Gatas, is a small island in barrio Playa in the municipality of Ponce in southern Puerto Rico. A tied island since the 1950s connected to the Puerto Rico mainland via a tombolo, Isla de Gatas is home to Club Náutico de Ponce, a private sports complex. It is located south of La Guancha and the Port of Ponce. Together with Caja de Muertos, Morrillito, Ratones, Cardona, Isla del Frio, and Isla de Jueyes, Gatas is one of seven islands in the municipality of Ponce.

Cyzicus (/ˈsɪzɪkəs/ SIZ-ik-əs; Ancient Greek: Κύζικος, romanized: Kúzikos; Ottoman Turkish: آیدینجق, romanized: Aydıncıḳ) was an ancient Greek town in Mysia in Anatolia in the current Balıkesir Province of Turkey. It was located on the shoreward side of the present Kapıdağ Peninsula (the classical Arctonnesus), a tombolo which is said to have originally been an island in the Sea of Marmara only to be connected to the mainland in historic times either by artificial means or an earthquake.

The site of Cyzicus, located on the Erdek and Bandırma roads, is protected by Turkey's Ministry of Culture.

A tied island or land-tied island is a landform consisting of an island that is connected to the mainland or another island only by a tombolo, which is an isthmus of beach materials connected to land at both ends. St Ninian's Isle in the Shetland Islands off the north coast of Scotland is an example: it was once an island but is now linked to the mainland.

Other examples include Maury Island, Washington in Puget Sound, Coronado, California, and Nahant, Massachusetts in the United States; Paraguana Peninsula in Venezuela; Barrenjoey, New South Wales and Wedge Island, Western Australia; Paratutae Island in New Zealand; the Argentario and Sestri Levante in Italy, Mount Hakodate in Japan, Howth Head in Ireland; Davaar Island, Campbeltown, Scotland; Chefoo island in Yantai, China; and Cheung Chau in Hong Kong.

An ayre is the name used for shingle beaches found in Orkney, Shetland, the Isle of Man, Lancashire, Cumbria and Northumbria. The word is derived from the Old Norse eyrr, meaning a shingle beach or gravelly place, and may be applied to ordinary beaches, cliff-foot beaches such as the Lang Ayre in Northmavine, Shetland, spits, bars or tombolos, but only if formed of shingle.

More than 130 such shingle beaches are named on Ordnance Survey maps of Shetland, but far fewer in Orkney, where most beaches are formed of sand. The word in its Old Norse form is common in Iceland, and it also occurs in a few place names in the north and west of the Scottish mainland which had a strong Norse influence, such as Eriboll ("a homestead on a shingle beach") and in the names of several shingle banks—Salt Ayre, Green Ayre, Stake Ayre, Rabbit Ayre and Whinny Ayre—in the tidal reach of the River Lune at Lancaster.
