This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

@J.R.: Summit and apex are also used outside of topographical or geographical context. Maybe the question is probing in that direction. –  KeyBrd Basher Oct 4 '13 at 7:04
@Key - I'd like to see the question probe in that direction – or any direction. –  J.R. Oct 4 '13 at 8:00

According to these definitions, they are completely interchangeable:

Peak -

the highest level or greatest degree

Summit -

the highest point

Apex -

the uppermost point

I don't think you can refer to the apex of a turn as the summit of the turn. –  Jim Oct 4 '13 at 1:21
"Peak" also has unique usages. "He peaked too early." –  Lumberjack Oct 4 '13 at 1:30
