The painstaking search of a site in the resort of Praia da Luz has been continuing, with a forensics officer joining the police team on Wednesday.
Work seems to have been concentrated in one particular area, with police going back and forth to a section of land at the perimeter of the site. Two tents have been erected here - it is unclear if that is to prevent the media from seeing what is being done or to provide shade.
While the police can't be seen from the beach, which is packed with holidaymakers enjoying the Algarve sun, everyone here seems all too aware of the investigation.
Christina, a 35-year-old from Bournemouth on holiday with family and friends, said: "We walked down here last night and it was quite scary seeing so many police around.
"The atmosphere here feels a bit flat because of what's happening. When you're on holiday you don't want to see police around but it's completely understandable."
Her friend Suzi, 34, said: "It's a bit of a shame because it's a lovely place and this does seem to have had an effect on the economy and on the people here.
"But if that was your child, you would want everything possible to be done."
Several people the BBC spoke to had not known, before arriving at the resort, that it was the place where Madeleine McCann was last seen.
Josie, 29, from Exeter, on holiday with her partner and one-year-old son, said: "It brings it home to you, being here - it makes it feel more real.
"We didn't realise when we booked that this was the place. It wasn't until I saw my dad I knew because he told me. I don't know if we would have come here otherwise.
"But police have to do what they have to do. We all want the best for the family."
The Met has also asked for two other locations in Praia da Luz to be examined, and those searches are expected to be completed by Friday.
But Portuguese police sources told the BBC the search may be extended if there is a significant find. Officers are believed to have been surprised by the difficulty of the terrain, while the police also need to consider the disruption to local residents.But Portuguese police sources told the BBC the search may be extended if there is a significant find.
