The seaside town of Cascais is only a 40 minute local train ride from Lisbon. After a quick walk through the town streets, we reached the jagged rock strewn coast. A walk along the road and in between the crags in the cliffs soon revealed that our feet could only take us so far. If we wanted to go further, we'd need a little assistance. We returned to town and rented electric bikes (absolutely loved these, no more worries about head winds or hills) to take us further down the coastline towards the distant sands of Guincho beach.
