Things not to do on mainland Greece…
Dehydrate. If you are here in summer, it can start to feel more like hell than a heavenly land of the gods. You can’t underestimate it, so always have plenty of water or take a break in the shade between 12-4pm to avoid the risk of sunstroke and dehydration. Bring your own water bottle too, as you don’t want to add to the plastic pile up.
On the other hand, don’t overuse water. Greece does, unsurprisingly, suffer from drought, so do all the sensible things regarding showers, flushing, brushing teeth and so on.
Greece’s economic crisis is far from over. It is like an odyssey that never ends, and so one of the most important things you can do here to be a responsible tourist is to support the local economy. Shop at the markets, eat out, hire local guides, use buses, stay in small, locally owned accommodation and tip well. International all inclusive resorts do not, in general, include local people’s interests.
Overlook wildlife. One of Greece’s best kept secrets is its population of nearly 400 bears, particularly in the north, around Northern Pindos National Park. Bird watching in the likes of Lake Kirkini is a-flutter with everything from pelicans to black kites, or in Parnassos National Park, where vultures and eagles are prolific. So, don’t forget your binoculars. Oh, and don’t go see dolphins in captivity. There is lots of wild marine life out there.
