Bicycling or walking, A2Z Adventures organises tours in Portugal since 2006. Because we are a Portuguese company, we take great pleasure in showing our charming country and taking you to those unique places that only locals know about. A2Z Adventures assumes its social and environmental responsibility working together with local guides, in the respect for local traditions and cultures. Because this is not enough, 1% of our revenues is donated to grassroots, social and environmental groups that make a difference in their local communities.
