Vacation for 10 days and travel along the coast, from Valesnia to Cartagena...That sounds like an interesting active vacation to me...
Do you have plans to do it? It does sound like a nice plan... I did travel to Lisbon from the Alicante area, but I did it in 7-8 days, which wasn't enough... So, your idea of 10 days for this area sounds perfect!
I meant this as a tour for you, since you mention revisiting that area 😀
I have had an idea about the next tour for years: Belgrade-Lisbon by plane, a tour of Lisbon and Sintra and then by car to Albufeira... With a tour of must-see locations along the way.
10 days. I believe that is enough?
Hmmm... We didn't visit Sintra, so I had to google it... Hehehe... Lisbon itself requires at least 6-7 days for exploration... We were 3-4 there and didn't check many things as it is huge! On the way from Lisbon to Valencia, you will need a month... hahahahaha... 😂
So many nice places to visit... :)
