Samariá Gorge is in southwest Crete and is a beautiful nature reserve, home to several rare animals and plants. The gorge itself is just under 10 miles (16 km long) and is both picturesque and a reasonably challenging hike, ideal for holiday-makers who want to do something more than lying on a beach. The best way to visit is with a group tour who will help to arrange transport so that your day runs smoothly.
