The mother of Jay Slater, the British teenager missing from Tenerife, said she spent eight hours at a police station on Friday while police outlined plans for the search.
Debbie Duncan told the Guardian she still believes “something unusual” may have happened to her son.
She flew to the Spanish island on Tuesday, the day after the 19-year-old went missing, to help with the search.
On Saturday, the sixth day of the search, police, rescue dogs and firefighters reunited at Rural de Teno park, where Slater’s phone was last registered.
Ms Duncan told the Guardian that police had said “noise levels” around the incident were affecting the investigation, but said she believed the search would “intensify”.
This comes after reports emerged that someone other than Mr Slater had logged into his Instagram account.
Rachel Louise Hague set up a GoFundMe page to support the search effort, as well as a Facebook page to support efforts to find him, and by Saturday afternoon had raised more than £26,000 of a £30,000 target.
She said the people who had “hacked” Mr Slater’s family’s social media accounts were “crazy”.
Ms Duncan said police had told her they were “following all the leads”.
“They all have a plan and a location,” she added.
“They have this map which they showed us, in different colours.”
She again asked the UK police for help in the search because there were “problems with the language barrier”.
However, Spanish police rejected an offer of assistance from Lancashire Police. Police said the case was “not within the remit of the UK police” but offered to assist Spanish police “if additional resources are required”.
Police added: “They confirmed they believe they have the necessary resources at the moment but the offer stands and they will contact us if the position changes.”
Mr Slater is from the police force. Police said his family continued to be supported by specialist police officers in the Lancashire town of Oswaldtwistle.
The apprentice bricklayer had been holidaying with friends in Tenerife before his disappearance, and attended the NRG music festival on Sunday.
He was last heard from just after 8am on Monday when he called his girlfriend, Lucy Lo, to tell her he had missed a bus and was planning to walk 11 hours to get home.
She said the man said he was lost, needed water and that his phone only had 1% charge.
