Puerto de La Estaca, Maritime port in Valverde, El Hierro, Spain.

Puerto de La Estaca is a maritime port on the eastern coast of El Hierro, protected by a substantial breakwater that shields vessels from rough sea conditions. The facilities enable the island's supply and regular ferry connections to other Canary Islands.

For a long time Puerto de La Estaca was El Hierro's only link with the outside world, until El Hierro Airport opened in 1972. An expansion begun in 1948 allowed ships to dock directly from 1960; before that a mail ship called weekly, then three ships a week linked the island with La Palma, La Gomera and Tenerife. The harbour and access road were rebuilt between 2002 and 2005 for 30 million euros.

The name La Estaca comes from the iron bar, estaca, to which sailboats once moored against the rock. The harbour began as a small fishing refuge, and the Playa del Varadero beside it still recalls that origin. The Alborán catamaran, built in Tasmania in 1999 and carrying almost 900 people, has linked the port with Los Cristianos since 2014.

The port is easily reached on foot, with ferry terminals located centrally within the port area. Visitors should note that services vary by season and waiting times can occur.
