Paddy McCarthy's team fell behind to a second half penalty but a late equaliser by Drew Matthews grabbed the point that the Eagles needed to finish top of the table, and match the achievements of the under-23s who won their league earlier this week.
That means that Palace's under-18s have secured a home tie in the semi-finals of the play-offs where they will face the runner-up in the northern section, which will either be Bolton Wanderers, Leeds United or Nottingham Forest.
