Greece's climate is Mediterranean, characterized by mild, rainy winters and hot, dry summers. Winter, from December to February, can be cold in mountainous areas, making certain trails impassable.
From March to May, the spring season brings pleasant temperatures and blossoming flora, ideal for hikes such as the famous Samaria Gorge.
Most hiking routes in Greece don't require permits. However, for trails in national parks, like Mount Olympus, a notification to the park's management might be necessary for safety reasons. For specific information, contact the Hellenic Ministry of Environment and Energy or local authorities. More info: Greek Ministry.
Wild camping is technically illegal in Greece, including beaches, forests, and archeological sites. Some hikers take the risk, but fines can be issued. Organized campsites are plentiful and provide a legal alternative. For more details, consult the Hellenic Ministry of Tourism's website: Visit Greece.
In Greece, the Hellenic Rescue Team, a volunteer organization, assists with mountain emergencies. Dial 112 for urgent assistance. It's advised to inform local authorities about your hiking plans, especially for challenging routes like Mount Olympus. More information here: https://www.hrt.org.gr/mountain-rescue.en.aspx.
Greece's diverse flora varies from olive groves in lowland areas to Alpine flowers in mountainous regions. Springtime brings a riot of wildflowers, particularly on Crete. However, summer's heat can result in parched landscapes. Stick to trails to protect the ecosystem. More info here: https://portal.cybertaxonomy.org/flora-greece/intro.
