First trip to Portugal begins in about 2 weeks. I'm happy to hear about alternate places or routes that meet my needs. The only 'must' points are Lagos over May Day weekend and Coimbra sometime during the Burning of the Ribbons from 5 May to 12 May. Number of nights at each destination subject to whim, weather and want.
Reasons for selecting destinations, beyond the place itself. Must have good access by public transit because I don't have a drivers license. Strong preferences for: 1) bus rides < 2hrs, train < 5 hrs, 2) Hilly terrain <3 days in a row, 3) Old buildings and what's inside them < 3 days in a row (unless it's Paris), 4) I love photography, so I stay overnight in places most people daytrip to. 5) I don't need to see any more Roman architecture, 6) Good walkability, from either a compact area or excellent public transit.
Arrive Lisbon. Leave Lisbon.
Cascais - For me, an out of season beach resort town is the best for getting over jet lag and travel fatigue. Lisbon is an easy day trip.
Sintra - Old buildings. Lisbon is an easy day trip.
Lagos - Base camp for the May Day weekend. Day trips west for photography. Day trips to the east as possible on Sun and Mon to see what hath expats wrought.
Obidos - Old buildings. Lisbon is doable as a day trip.
Nazare - Compact tourist area, excellent photo ops, short ride from Obidos.
Figueira da Foz - Heavily tourist oriented beach towns during the off season appeal to me. Short ride from Nazare, easy access to Coimbra.
Coimbra - Burning of the Ribbons. Old buildings. Fast access to Porto and Lisbon.
TBD in Porto & Douro and/or Lisbon.
Depart Porto or Lisbon for France (have tickets for both).
Thanks.
