From Ovidos can you cover Nazare, Alcobaca and Batalha and reach Coimbra at night?

So, you would visit the two monasteries in Alcobaça and Batalha only? If so, it would take 2h 15m if you didn’t stop along the way so I would say yes. The last entrance time is 5:30p allowing you 30m to go through it. I’ve been to a monastery in Belém that didn’t require a lot of time. Both places interior look pretty bare so you won't need a lot of time there.

Yes, it’s possible. But, on my scouting trip before moving to Portugal, I visited both Alcobaça and Batalha in one week and had no memory of the differences! They are both nice, especially Alcobaça but seeing both in one day might be a bit much. I would personally spend more time in Coimbra instead. Nazaré is a beach town and not much more. But if you drive to the overlook above town the views are pretty spectacular.

You didn’t ask this question but I have to mention your one night stays. That really leaves you a few hours at most in the actual town. Driving distances seem to be minimized when you read about them online. You are going to spend the bulk of your time driving on your current itinerary. You might give some thought to cutting down on your overnights and spending 2-3 days in one place and doing day trips rather than the constant moving of hotels.

Obidos is worth a couple of hours and wouldn’t be my choice of an overnight. Not certain why you have chosen Belmonte. I visited Belmonte on a tour of the 12 historic villages of Portugal and it was one of the ones I wished we had skipped. If you are driving from the Douro (and there is a decent road) you might want to check out Castelo Rodrigo instead of Belmonte.

You didn’t say when you are coming but be aware the Alentejo and Évora are very hot in the summer.
And, yes, the rock formations around Lagos are amazing.

I too wouldn’t stay on Obidos - it’s worth a couple of hours. Caldas da Rainha or somewhere on the coast would be my choice of an overnight stop. I covered Alcobaca and Batalha in one day from Caldas. If your time is short, drop one. Fatima was my least favourite town in this area. I liked Tomar.

I think you are trying to cover far too much ground in your timescale. It will be a blur. Don’t underestimate how long it will take in Portugal to get around when you aren’t on the toll roads. I rarely do anything in the times that Google maps suggests - add a third plus time for photo and coffee stops.

Personally, I would drop the Algarve, as your time there is far too rushed. It’s a 3+ hour drive from Evora to Tavira on the rather boring toll roads. That leaves half a day to see Tavira, a pretty place. Tavira to Lagos is 2 + hours avoiding the toll road and going through more interesting places. It’s an hour and a quarter by toll road. The rocks around Lagos are interesting, but the folded rock formations stretch north up the western coast, so you could see the formations as a day trip from Lisbon, rather than the upheaval of moving accommodation again.

Nazare is my least favourite resort on this coast and IMO overrated by RS. It was more interesting a decade ago before it was overdeveloped and become a surfers hangout.

I seem to recall in a previous post that you are travelling this September. The Algarve is usually busy then, but this year in particular, it will be overrun with tourists. It’s one of the few places that the U.K. yesterday said is safe to travel to and the only beach destination, so apparently bookings have rocketed and prices are increasing rapidly.

Petrol and diesel is expensive in Portugal - more so than the U.K. and particularly if you are coming from North America. As your trip stands, sorry to say you will be spending as long in the car as you will actually visiting places. I haven’t visited Belmonte, but it’s a lot of driving just for one night there. I think your trip would be more enjoyable if you stayed in Lisbon - Caldas/coast - Coimbra - Douro - Porto - [Evora] - Lisbon, which is still a brisk pace.

We took the RS Heart of Portugal in 12 days Tour a few years ago. We were there in September. Your itinerary is similar minus the Algarve. Our least favorite town was Obidos. It's known as "the wedding town." It was noisy at night, & overcrowded during the day. That said, logistically it worked well for visiting Alcobaca, Nazare, Batalha and Fatima. Fatima was our least favorite stop. We felt the one night we stayed in Evora was fine. Our favorite stays were Lisbon, Coimbra, Douro Valley and Porto. I would also agree to eliminate the Algarve. Perhaps add to the Douro Valley and or Porto? We did a wonderful guided tour of Sintra and Cascais with www.lisbonriders.com. We stayed a total of 5 nights in Lisbon and felt their was plenty to see. I can't speak to Belmonte, but I just looked it up and it piqued my interest, especially for the Jewish history. Any plans to hire a local guide there?

Yes, this can definitely be done in a day. I did it going north to south and it was a pleasant day having a late lunch in Nazaré before visiting Alcobaca and spending the night in Obidos. I also love the recommendation above about visiting Castelo Rodrigo, a charming disused town. I stayed at a great B&B Casa da Cisterna. The lady who runs the place offers tours to the Foz Coa National Park to view the petroglyphs. You arrive at the site as the sun is setting and she explains why people settled here millennia ago. As the darkness comes, she leads you into the park (she has keys for the gates) to the ancient drawings. Using flashlights, she illuminates the figures and because of the shadows, they really become very visible. As Rick 2ould say, a WOW moment!

In Evora, I stayed at the enjoyable and convenient Pensao Residencial Policarpo. Great hosts, wonderful breakfast and free parking. In Evora, you MUST dine at Botequim Da Mouraria. But get there early. There only about 12 seats at a counter but the food is the best I ate in Portugal. I don’t think they take reservations.
