Brief Greek Island Getwaway?

Hi all,

I was working on planning a trip to the Greek Islands at the end of the month, but seeing as how there are so many islands and limited time on my itinerary, I wanted some insight on which place might suit my vibe the most.

I’m 25M and am totally into lounging on the beach, hiking, and swimming around. I also do have a wild side and enjoy partying hard. I don’t typically like hanging out with 18-21 year olds and enjoy the mid 20s and older partygoers. Naturally, the research I’ve done points to Mykonos or Ios. But I’ve also seen suggestions for Crete, Zakynthos, and Corfu. I’m open to staying in hostels of course, but luckily money is not the biggest factor this trip.

I’m looking to stay 3-5 nights out there, and then I’m returning to Germany for the remainder of my trip. Does anybody have any experience with Greece that could give me insight on which islands I mentioned may be best for people like me?
