I would like to ask, what are the places I should be visiting while I am in Terceira. I will be in the island for 3 weeks! Will be staying at Angro De Heroishmo throughout the 3 weeks. Would also like to ask, are there any vegetarian restaurants available there? Looking forward for this trip! I am a Singaporean do I need a visa to be in Portugal for 7 weeks...? 3 weeks Terceira, 4 weeks mainland Portugal , for holidays. please advise..
