hiking in Spain?

YuLing - I think you should consider Northern Spain, especially Basque Country. I did not hike but drove on this last visit but this region is just breathtaking - from mountains to coastlines and vineyards to medieval towns. There is the Oma Painted Forest in the Urdaibai Biosphere Reserve as well as the Gorbeia National Park. There are breathtaking trails along the coastline and one of sights I missed on this trip is San Juan de Gaztelugatxe. The one caveat I have is that knowing some Spanish or having a good translation app is essential if you want to go deep into Basque Country.

Caminito Del Rey sounded interesting and I had filed that thought away for when we get back.

There are plenty of nature activities in the Picos de Europa area, so you may want to do some research to see what all is there. Of course, you could always walk a portion of the Camino de Santiago. There are some beautiful views from parts of it.

Hi. If you decide southern spain check out Antequera. Its about an hour from Malaga. You could hike the Camanita del Rey which is about an hours drive from there. Also El Torcal is only a 20 minute drive from town. Fabulous park through otherworldly limestone formations. We loved it. Antequera is a great town to spend a few nights.

There are multiple Camino routes in Spain that are great for hiking as they have the infrastructure for sleeping, eating, etc. so you don't have to carry food or tents with you.
