I'm looking for ideas on where to spend 3 nights/days when my husband and I first arrive in Portugal in early April. We plan to arrive on a Sunday, rent a car, and would like to drive one to 3 hours north of Lisbon (perhaps Coimbra or the Silver Coast), and would like to stay in one location to get adjusted to the time change, and sightsee, walk, hike, before returning to Lisbon. When we get back to Lisbon, we will return the car, and have an additional 2 and a half days to see Sintra, and the sights in Lisbon. Then we will join a bike tour that takes us to the Evora and Algarve.
I'd love suggestions for either an area north of Lisbon to base ourselves or even specific hotels or pousadas. Thanks!
