About 240 people will be sleeping rough in Cornwall each night over Christmas, according to a local charity.
Steve Ellis, from the St Petroc's Society, said many people were unaware of the extent of the problem of homelessness in the county.
He said the figure was difficult to work out as homeless people there often slept in fields or woodlands.
Meanwhile, the charity said it would work to ensure a breakfast club kept running despite concerns over its base.
Mr Ellis homelessness in Cornwall was a "real difficulty" because people who were homeless were "not easily visible".
He said: "If you think of the stereotypical view in cities of people in shop doorways, that just doesn't happen in Cornwall.
"People are sleeping in fields, or in woodland areas. They're sleeping in all kinds of remote places."
Meanwhile, the charity's breakfast club for the homeless is facing having to find new accommodation.
The daily facility is currently run at St Paul's Church Hall in Truro.
The charity said it had been told that it was possible that the building would have to be sold.
Mr Ellis said: "We will be doing all we can to endure that the service continues throughout 2011."
