planning on spending a month in Portugal. Looking for advice on where to go that would be near hiking trails that we could access by bus or directly to the trail
Also, where can I buy the Sunflower hiking trails of Portugal
Have you checked the fisherman's trail in Alentejo and Algarve Region? It's a long multi-day hike, but the region is amazing...
Maybe this will be of interest

There are also the Camino Portugues from Lisbon north through Tomar, Coimbra, Porto (along the coast or inland), Guimaraes,Braga, Valenca Portugal on to Santiago de Compostela Spain or Camino Fatima which are both well marked and a mixture of urban and rural.
Walking the Camino would be the easiest. Go for the central route out of Porto. Follow the yellow arrows.
