Cycling day trip from Cascais to Rio de Mouro

This scenic cycling route kicks off from the charming seaside town of Cascais, a favorite getaway near Lisbon known for its beautiful beaches, bustling marina, and elegant old town streets. From there, you’ll pedal northeast for roughly 25 km towards Rio de Mouro, a quieter, residential spot nestled at the edge of the Sintra hills.

Be ready for a bit of a workout—the route involves a 416-meter ascent, but there’s also a generous descent as you leave the coast behind. Most of the way follows quiet roads and tracks, so you’ll cruise through a mix of urban outskirts, green landscapes, and maybe spot some classic Portuguese villages along the way. While the majority of surfaces are missing or mixed, about a quarter is smooth asphalt or concrete, so a sturdy hybrid bike will do nicely.

Finish up in Rio de Mouro, where you can relax in local cafes or explore some lesser-known corners of the Sintra area. It’s a rewarding ride with a blend of coastal cool and country calm—perfect for a half-day cycling escape!
