I'll be in Spain in August. I want to do some day hiking into the Pyrenees while I am there. I need suggestions on routes. What city should I travel to to start my hike? I've heard there are day hikes in where you can stay at mountain huts. Anyone know anything about these? Thanks!
I've been chipping away at the Pyrenees from the French side for the last couple of years.
Try this for the Spanish side: http://www.lespyrenees.net
There is the Parque Nacional de Ordesa y Monte Perdido and the Parque Nacional de Sierra Y Canones de Guara. Both are not far from Jaca in the Aragone.
There is also the partial routes of the Camino de Santiago. One crosses the pyrenees going from St Jean Pied de Port in France to Roncesvalles in Spain, and another goes from Somport in France to Jaca in Spain (both carry "pilgrims" on their way to Santiago de Compostela). I know that there are hostel type facilities for pilgrims. I've no knowledge of mountain huts.
I've never hiked this area (Jaca), only driven. It's beautiful.
I just ran across a website, quite by accident, that you might want to take a look at.

It's actually a travel site that is selling guided hikes in the Spanish pyrenees. I know that you are probably not looking for guided hikes, but it does list itineraries of their hikes. Might be useful to you.
