What level to quest in these zones is optimal?

My favorite zones are Zangar Marsh and ZulDrak. I was wondering what level range for each of these zones, as i don't want to miss them!!
THanks guys!!

I think 64+ for Zangar and 74+ for Zul

I believe 60 was enough for Zangarmarsh

I usually go Zangramarsh at 62, There are quests but more will appear the higher you get in level.
