In the Discovery Science registration form you may also register for two different touristic tours, made available by our registration office:
Porto City Tour - Half Day (Eur. 35,00)
Minho Tour - Full Day (Eur. 75,00)
The arrangements for these tours, including the schedules, are made with the participants, so that there is a given degree of freedom for each participant to decide when to take them. However, we should note that a tour will only occur if at least 30 participants enroll.
