Trälhavet, Glacial fjard in Stockholm archipelago, Sweden

Trälhavet is a fjard in the inner Stockholm archipelago, bounded by Resarö to the south, Åkersberga to the north and Saxarfjärden to the east. The main shipping lanes to Stockholm cross it through Kodjupet or Oxdjupet, and the Furusund and Sandhamn routes meet here. In winter the surface freezes into pale grey-white ice crossed by long dark cracks, with two small figures standing in the middle distance.

The name Trälhavet, recorded as Trælahaff in the 1400s, may derive from träl, meaning 'slave', comparable to the nickname Grodhavet for Lake Mälaren. The water has long carried the main fairways from the Baltic to Stockholm's harbour, where Furusundsleden and Sandhamnsleden meet.

The name Trälhavet, recorded as Trælahaff in the 1400s, may derive from träl, meaning 'slave', comparable to the nickname Grodhavet for Lake Mälaren. The term was also used jokingly for office landscapes, especially daily and evening newspaper editorial offices.

This waterway can be reached through several navigation channels, with Kodjupet and Oxdjupet serving as main routes for traffic toward Stockholm. Visitors should know that conditions change with the weather and seasons, and local knowledge helps with planning a visit.

This waterway connects to neighboring Säterfjärden through the Rödbosund strait, forming a larger interconnected water system. This connection allows for an interesting journey between different parts of the archipelago.
