Most cities have plenty of hiking and camping groups you can join. Hiking and other outdoor activities have grown considerably in popularity in the last couple of decades.
Lots of stone path walkways which people will refer to as hiking, but isn't what most in Europe or the US would consider it to be. There are groups that build off old paths that connect villages or which were used for hunting. Some areas have really nice networks of trails, though, just not to the extent you'd find elsewhere.
