We are delighted to offer you an exclusive opportunity to share a butterfly watching holiday in the wonderful setting of the Picos de Europa in northern Spain!

The Picos is at the core of The Cantabrian Mountain range, which stretches along the north coast of Spain for about 300 kilometres. It is one of the most beautiful and beguiling parts of the whole region.

Over 150 butterfly species reside among the spectacular and rugged range of limestone mountains. Our daily excursions from the attractive and unspoilt village which is our base, will take in a variety of habitats and scenery, including flower rich meadows fizzing with a range of fritillaries and other goodies, woodlands and sunlit glades and then up into the mountains themselves for alpine treasures, hidden among rocky pastures and limestone pavement!

We should see a good number of different butterfly species, just under 100 were recorded in 2019 and 2022. These included stars such as the Apollo and Gavarnie Blue, Bog Fritillary, dusky large blue, Camberwell Beauty, Chapman’s Ringlet and Large Chequered Skipper.

This promises to be a very popular tour – we recommend booking early to avoid disappointment!


This itinerary is subject to change as we react to changing weather conditions – we will adjust plans to maximise our chances of seeing as many butterflies as we can, and enjoy the best of the sunshine in the best places.

Day 1: Stansted to Santander, Santander to Boca de Huérgano

The path is surrounded by Cytisus oromediterraneus and Quercus pyrenaica and is also good for butterflies: Provençal and Heath Fritillary, Chestnut and Pearly Heath among others. Beautiful plants such as Linaria triornithophora should be around.

We will keep an eye for Rock Bunting, Dipper and mammals such as Southern Chamois. After this, we will visit the quaint village of Lois and the Cathedral “Catedral de la Montaña” a nice white church, quite big considering the small size of the village.

Here in the village can be also found “La casa del humo” (the smoke house). It seems that years go by the houses didn’t have chimneys and all the smoke went out towards the straw roof. People did it in order to isolate the house from the cold and to avoid insects, small mammals and birds to nest in the straw. The walls and the roof of the house are covered by tick layers of soot, there are even stalactites.  There are’t any other houses like this in all of the Picos Mountains.
