Kos hiking is rarely extreme alpine terrain, but the island can still humble you if you show up with flip-flops and half a bottle of water. Most day hikes here mix exposed ridges, stone tracks, and village stops — so pack for heat, wind, and uneven ground.
Essentials
- Water: at least 1.5–2 litres per person for anything over 6 km. Refill points are not guaranteed on mountain routes.
- Sun protection: hat, SPF 50, and sunglasses. Shade is scarce on Dikeos and coastal sections.
- Footwear: trail runners or light hiking shoes with grip. Avoid sandals on summit paths.
- Offline maps: download your region in TrailKos before you lose signal.
Nice to have
- Light windbreaker — spring and autumn evenings cool fast above Zia.
- Snacks with salt (nuts, trail mix) for longer routes like Mt. Dikeos Summit.
- Power bank if you use your phone for navigation and photos.
- Small first-aid kit: blister plasters are the most-used item.
What to leave behind
Heavy boots unless you prefer them — most Kos trails are dry dirt and limestone, not mud. Skip the massive backpack for a 4 km village loop; a small day pack is enough.
Check the trail difficulty and duration in the app before you go. An "easy" coastal walk still needs water when the sun is high.
