Cliff Jumping near Taipei

Hello, I'll be in Taipei for a few months and was wondering if anyone knew of any good, safe cliff jumping places nearby? Let me know!

I can't name any places off the top of my head. cliff jumping is not my thing.

The mountains of central Taiwan are quite sheer and high, but not what I would call cliffs. The east coast, even areas not far from Taipei, definitely has cliffs, but the beaches are quite narrow so having a boat waiting nearby might be a good idea.

It's not hard to find rock climbing, and bungee jumping opportunities in Taiwan, but cliff diving never came across my radar there.
