Mjölkö or Mjölkön is an island in Österåkers municipality about 3 km east of Åkersberga. The island consists of around 120 residences and the number of residents during the 2000s has been few. The Mjölkö community association manages approximately 10 km gravel roads, several docks, and water areas around the island. The association also arranges midsummer celebrations and other social activities. The island is operated by Waxholmsbolaget. The island's name is derived from that the mainland farmers used to have their cows on the island during the summer months and traveled there every day to milk them.

Roslagen is a coastal area in eastern Uppland in Sweden. It constitutes the northern part of the Stockholm archipelago and extends north along the coast. The old designation for the area was Roden. In the Viking Age, Roden was divided into skeppslag ("ship districts"), each responsible for supplying ships and crews when the king issued a call to the leidang, the conscript navy system. Unlike the inland hundreds, Roden lay outside the regular division of the Uppland folklands. It mainly covered the coastal areas of Tiundaland and Attundaland, sometimes reaching into Gästrikland, and in some sources even included islands further south such as Lidingö and Värmdö. Over time, especially from the 1500s onward, the term Roslagen came to be used more generally for the entire Uppland coast and even some inland areas. A person from Roslagen is called a Rospigg, a modernized form of rosbyggiar ("inhabitant of Roden"). The area also gives its name to the endangered domesticated Roslag sheep, which originated from the area centuries ago.

Stegesund-Hästholmen is an island, sometimes considered a pair of islands, in the Stockholm archipelago in Sweden. Stegesund-Hästholmen is situated in Vaxholm Municipality and Stockholm County. Hästholmen (to the west) and Stegesund (to the east) are separated by an artificial channel, constructed in 1899, and connected by a bridge. The island has a permanent population of about 20 people. To the north, west and south, Stegesund-Hästholmen is separated from the islands of Resarö, Edholma and Vaxön by the winding northern section of the Kodjupet strait, whilst to the east it is separated from the island of Skarpö by the much narrower Stegesundet strait. The artificial channel between Stegesund and Hästholmen is only navigable by very small boats, such as dinghies and canoes. Stegesund-Hästholmen has no road connection to the mainland or other islands. It is served throughout the year by passenger ships of the Waxholmsbolaget, which call at either the Vikingsborg pier (on Hästholmen) or the Stegesund pier (on Stegesund), providing a connection to Vaxholm town and Stockholm city.

Stegesundet is a very narrow strait in Sweden's Stockholm Archipelago. It separates the islands of Stegesund-Hästholmen (to the west) and Skarpö (to the east), and provides a shorter route than the section of the Kodjupet strait that passes to the west of Stegesund-Hästholmen. The strait is too restricted for most commercial shipping, but is used by pleasure craft, Waxholmsbolaget ships, and other local ferries. Some of the Waxholmsbolaget ships and local ferries call at Stegesund and Skarpöborg piers on either side of the strait.

Ytterby (Swedish pronunciation: [ˈʏ̂tːɛrˌbyː]) is a village on the Swedish island of Resarö, in Vaxholm Municipality in the Stockholm archipelago. Today the residential area is dominated by suburban homes. The Swedish name of the village translates literally into "outer village". Ytterby is the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), terbium (Tb), erbium (Er), and ytterbium (Yb) are all named after Ytterby, and the elements holmium (Ho), scandium (Sc), thulium (Tm), tantalum (Ta), and gadolinium (Gd) were also first discovered there. Local roads connect Ytterby to county road 274 and hence the mainland. Except for the winter months, passenger ships of the Waxholmsbolaget call at a pier in Ytterby, providing a connection to Vaxholm town and Stockholm. Ytterby is as well served by several local bus lines of the north east SL district, connecting the area directly to Stockholms Östra station.

Skarpö is an island in the Stockholm archipelago in Sweden. It is situated in Vaxholm Municipality and Stockholm County. The southern and western half of the island comprises the Skarpö urban area. A road bridge and local road connects Skarpö to county road 274 on the adjoining island of Rindö to the south. Rindö is in turn connected to Vaxholm town by the Vaxholmsleden car ferry at its western end, and to Värmdö island by the Oxdjupsleden car ferry at its eastern end. To the west, Skarpö is separated from the island of Stegesund by the very narrow Stegesundet strait, which is used by Waxholmsbolaget ships, and other local ferries, that serve the outer archipelago. Some of these call at Skarpöborg pier on the Skarpö shore of the Stegesundet strait, providing a connection to Vaxholm town and Stockholm city.

Skarpö is an urban area comprising the southern and western half of the island of Skarpö in Vaxholm Municipality, Stockholm County, Sweden.In 2020, the urban area had an area of 103 hectares (250 acres) and a population of 257.

Resarö is an island in the Stockholm archipelago and a locality in Vaxholm Municipality, Stockholm County, Sweden. The island is divided into four populated areas: Överby, Ytterby, Storäng, Engarn and Ladvik, of which Ytterby notably is the most famous one because of its local mine. It had 3,212 inhabitants in 2020. Resarö includes the hamlet of Ytterby, famous for the discovery of several rare-earth elements in a local mine. At its southern end, the island is crossed by county road 274, with a bridge to the south linking it to the island of Kullö and, via that, to the Vaxholm urban area. To the west, a bridge links to the mainland via the islet of Bullerholmen. Local roads connect the county road with centres of population to the north of the island. Except for the winter months, passenger ships of the Waxholmsbolaget call at a pier in Ytterby, providing a connection to Vaxholm town and Stockholm city.

Kodjupet is a strait in Sweden's Stockholm Archipelago. Along with the Oxdjupet strait, it is one of two shipping routes connecting the open sea to the city of Stockholm, passing either side of the island of Rindö. Today the Kodjupet is suitable only for smaller vessels, due to its narrow and twisting nature together with a minimum water depth of 3.3 metres (11 ft), but it was formerly the principal route for commercial and naval ships. It passes close offshore of the town of Vaxholm. Although winding in nature, the strait runs broadly from north to south on its route from the sea to the city. It is flanked by the islands of Resarö, Edholma and Vaxön to the west, and Stegesund-Hästholmen, Skarpö and Rindö to the east. The very narrow Stegesundet strait provides a short-cut to the northern part of the Kodjupet strait, passing between the islands of Stegesund-Hästholmen and Skarpö. In 1548, Gustav Vasa constructed the Vaxholm Fortress on an islet in the middle of the southern part of the Kodjupet strait between Vaxön and Rindö. The Oxdjupet strait was, at the same time, artificially reduced in depth in order to prevent its use. Thus, the fortress was strategically situated to defend the city of Stockholm against shipborne attacks from the sea. The fortress has resisted several attacks, has been rebuilt on a number of occasions, and still stands. By the latter half of the 19th century, the Kodjupet strait was proving problematic for the period's larger ships, and in 1879 the main shipping route into Stockholm was diverted to use the Oxdjupet strait, which was dredged to remove its previous artificial obstructions. The strait is crossed by the Vaxholmsleden car ferry, which connects Vaxholm to Rindö, and by the Kastellet ferry, an electrically powered cable ferry that provides passenger access to Vaxholm Fortress.
