The surfing venues of Praia da Barra and Costa Nova , 13km west of Aveiro, are good for a day’s outing. Prettier Costa Nova has a beachside street lined with cafes, kitsch gift shops and picturesque candy-striped cottages. Buses go (€2.50/4 single/return, hourly) from Aveiro's Rua Clube dos Galitos.
Wilder and more remote is Praia de São Jacinto , on the northern side of the lagoon. The vast beach of dunes is a 1.5km walk from São Jacinto port, through a residential area at the back of town. Take a bus from Aveiro to Forte da Barra (single/return €2.50/4), where there is a ferry to São Jacinto (passenger/car return €3/5). Schedules for boats are at www.moveaveiro.pt; bus schedules are at www.transdev.pt. Drivers can also circumnavigate the lagoon and arrive from the north via Ovar, a much longer trip.
