History

Conservation
Stick to marked paths to protect fragile riparian vegetation; avoid leaving litter on the beach and use biodegradable sunscreen to reduce impact on coastal waters.

Start early for cooler temperatures
Begin the hike in the morning to avoid midday sun on exposed sections and to catch fresher river pools at Lefka.
Footwear matters
Use sturdy, grippy hiking shoes—river crossings and loose schist make trail footing variable.
Carry at least 1–2 liters of water
Although the Arni river flows, potable water isn’t guaranteed on the route; pack hydration and electrolytes.
Protect swim items in a dry bag
Bring swimwear and a quick-dry towel in a waterproof bag—the beach stop includes a brunch and a short swim window.
Sturdy hiking shoes
Provide traction on loose schist, rocky ravines and damp riverbanks.
Daypack with hydration (1–2 L)
Carry water, snacks, sunscreen and a light layer for the beach stop.
Swimwear and quick-dry towel
Needed for the beach picnic and the short swim at Lefka.

Sun protection (hat, sunscreen, sunglasses)
