Thanks gentlemen.
Portugal is about to enter a so-called "soft" lockdown, to balance the rise in infected people with the impact on economy. Similar to the rest of Europe, no country can at this junction close down fully again. Hopefully, I will still be able to travel and keep doing more hikes in the region. It is perfectly safe, since Odemira is the municipality with the higher ratio of area/population. It is the largest muncipality in area, and has the lowest population.
