One night near Heraklion
We're staying with a group of friends for a week in the Heraklion area. I mistakenly booked our flight out for one day after we check out of the place we're staying in the Agia Pelagia area. So we need to book something for one night that's within an hour or so of the Heraklion airport.
Obviously we could find something cheap nearby, but I'm wondering if anyone has suggestions for an interesting area that might make for a fun last day. We're more into nature (coastal or mountains) than nightlife. I'd like to turn my mistake into a fun opportunity!
