I've been travelling throughout Portugal quite extensively using a combination of OSM-OFM-Velomap digital maps.
I've found them extremely detailed with always pretty reliable indications of tracks, dirt roads, minor tarmac roads, rivers, power lines, farms, etc.
Of course even main roads as well as IPs and ICs highways, respectively Itinerario Principal
and Itinerario Complementar
, are very well indicated.NEVER
needed any type of paper maps, not inside big conurbations like Lisboa and Porto nor in the most remote parts of the Country.REMARK
: Velomap and OFM are complete of relevant elevation data that allow you to work-out pretty reliable elevation profiles as well as gradient, cumulative climbing, etc.
