A student has pleaded guilty to sneaking into Mar-a-Lago last northern autumn during one of US President Donald Trump's visits to his Florida club.

University of Wisconsin student Mark Lindblom apologised today and received a year's probation after prosecutors agreed he meant no harm.

Lindblom was visiting his grandparents at a neighbouring resort on November 23 when he stood in line with entering Mar-a-Lago members.

The Palm Beach Post reports he walked past signs warning that only authorised people were allowed. He then went through a metal detector and Secret Service agents let him enter.

The 19-year-old Lindblom was later confronted by agents and removed.

Prosecutor John McMillan said the Secret Service has since tightened security.

A Chinese national is awaiting trial on charges she illegally entered Mar-a-Lago in March.
