Prospect Park visitors will have to pick a different spot for their afternoon stroll Friday.

The entire 585-acre park will be closed from noon to 6 p.m. as a security precaution for President Barack Obama's visit to Brooklyn, the Prospect Park Alliance announced yesterday.

Obama will be in the city for a fundraiser but he will also speak with the students at the Pathways in Technology Early College High School in Crown Heights.

He touted the school's academic success during his State of the Union address this year.
