Cycling along the river always seems like a good idea, until it’s time to go home, and you find yourself going up whatever Lisbon hill you’re staying on like you’re in the Tour de France. To avoid this, rent your bike at Belém Bike. If your legs can take a whole day of pedalling, it will cost you €10 and sore thighs. If you want to cycle between Baixa and Belém, that can also be arranged. Lisbon Bike Rentals, in Cais do Sodré, rents mountain bikes, road bikes and even electric bikes, for €20/3 hours.
