Love Gaia GPS
I have been using this app all around the world. Great offline terrain navigation, and even urban to a certain extent. Love the different layers! We hike, we bike, we orient and pin our urban locations for general reference. Countries visited and hiked using Gaia: Turkey, Armenia, Georgia, Ecuador (including the Galapagos), Colombia, and all around the USA.
