Going North is also worthwhile when exploring Portugal. Make Porto your base and visit Northern cities like Braga or Chaves, or drive along the Douro River into Spain. And if you’re looking to be in touch with nature, venture in to the mountains and explore Portugal’s only National Park, Peneda-Gerês. Here you’ll find paradise-like waterfalls, challenging hiking trails and rewarding views. The surrounding towns and villages are good options for a more comfortable night’s sleep. And another mountain destination is Serra da Estrela, in the northern countryside Beira Interior, which is also close to quaint villages like Piódão.
