Chania? Heraklion? Rethimno? I got 8 days and trying to keep a tight budget. Leaving for Crete on Tuesday so Im doing some last minute planning. 

8 days not including travel days. Ferry arrives in Heraklion and flight leaves there too. I've heard good things about Chania and it seems like a good place to wander. The only thing I can think of that attracts me Heraklion are the Minoan ruins which I do want to see. 

Current plan is to land in Heraklion spend the night (late ferry) then go to Chania the next day. 3 days Chania &gt; travel day to Heraklion &gt; 3 days Heraklion &gt; travel day airport. 

More time in Chania to just chill?

I'm also without a car. Where is better for easy beach access and/or nature walking access? 

Rethimno?
