A Guarda is the last town in Galicia: a colourful fishing port wedged between the Atlantic and the mouth of the river Miño, with Portugal on the far bank. It is known across Spain for its lobster and for the conical hill that rises behind it.
That hill is Monte Santa Trega, 341 metres high, and on its slopes lies one of the largest and best-known castros — fortified Iron Age settlements — in the north-west of the Iberian Peninsula, occupied around the time the Romans arrived.
Top things to do: A Guarda & Monte Santa Trega
Explore the castro
The excavated part of the settlement is a honeycomb of round stone houses, some with porches and yards, threaded by paved lanes and drains. A couple of dwellings have been rebuilt with thatched roofs to show how they looked.
Go to the summit
At the top are a small archaeological museum with finds from the site, a hermitage and a viewpoint over the Miño estuary, the beaches of northern Portugal and the Atlantic. On a clear day it is one of the great panoramas of Galicia.
Eat on the harbour
A Guarda’s seafront is lined with narrow, brightly painted fishermen’s houses and seafood restaurants. Lobster is the speciality — the town holds a festival in its honour in early summer — but the day’s fish is easier on the wallet.
Walk by the estuary
South of town, footpaths and boardwalks follow the Miño estuary past river beaches and pinewoods, with Portugal a few hundred metres across the water. It is good, gentle birdwatching country.
