8 Day Itinerary for Portugal

You can skip Aveiro, in my opinion. We were underwhelmed with the canals. Hope you’re using Lisbon Riders for your Sintra day - we really enjoyed them.

Aviero is ok for a quick look but I agree with the poster above.
I would not want to stay overnight in touristy Nazare, stopping for lunch by the beach was more than enough for us. Perhaps it won’t be so jam packed with tourists in May as it was when we visited there in mid-June. It is known for it’s big waves for surfing.
Why aren’t you including interesting and historic Coimbra?? You definitely need to visit it, one of Portugal’s top sites, stay overnight there instead of in touristy Nazare! We loved our stay at the Quinta de las Lagrimas in Coimbra.
We enjoyed seeing Alcobaça which is not far from Nazare but skipped Fatima. The Portuguese Royal Tombs including those of King Pedro and his beloved Inés are in Alcobaça Cathedral, a beautiful, historic building. Google “King Pedro and Inés” for an interesting story!

I’m in Coimbra now and we are enjoying our overnight stay. We visited and toured the university’s sights, science museum, chapel, great hall and King João III’s Library. The old town is small but charming.

We enjoyed the Douro River Valley tour with Living Tour. We had a great guide. We visited Amarante, two quintas, (2 tastings and one included lunch) and rode on the river upstream from Pinhão for 50 minutes. 8:30-6:30 for 95 euros but they offer discounts of 5 euros when signing up.

I completely agree with comments re: Coimbra. Definitely worth a night and full day, at least. Fantastic spot for a night between Porto and Lisbon.

Thank you all for your advice! I will give Coimbra
a another look
