Overnight it was quite chilly so we stayed in bed until it had warmed up a little. After breakfast the first stop was Ojo Guareña.
Ojo Guareña is a karst complex located in the Cantabrian Mountains of Castile and Leon, Spain, declared a natural monument by the government of Castile and Leon in 1996. It is composed of over 90 kilometres (56 mi) of galleries and passages within an area of some 13,850 hectares (34,200 acres). The limestone formation containing the system is approximately 100 metres (330 ft) thick and sits on a massive water-resistant layer of marl. The caves were formed in the limestone by erosion sometime within the Coniacian Age. Ojo Guareña was considered the greatest karst system of the Iberian Peninsula until 2009, when a significant length of new passages was discovered in the Mortillano system.
Archaeological findings in the area indicate that various caves in the Ojo Guareña system were used by humans as early as the Middle Palaeolithic up until the Middle Ages. Scientific exploration has also discovered the presence of over 180 species of invertebrates in the complex.
It was pretty deserted as it doesn’t open until Saturday, so we couldn’t explore inside the caves. However, it was still worth the trip as the views were spectacular.
After a lunch of bread, cheese and ham sat outside the van in the warm sunshine, listening to a woodpecker, we set off for Burgos. The scenery in the valleys and mountains was beautiful and is part of the experience of van life. The roads were very quiet, however, the Spanish do like to drive fast and overtook us very quickly!
We arrived at Fuentas Blancas campsite. It’s on the river and less than 4km from Burgos centre, so when we arrived, we quickly set up and got out the Brompton bikes and rode in to town.
When we got back to the site, I had my first go at folding up the Brompton…
