Wear grippy shoes
Stone steps at Gaztelugatxe are uneven and can be slippery when wet; sturdy, treaded footwear makes the climb safer and more comfortable.
Bring a windproof layer
Coastal winds can be cold and persistent even on sunny days — pack a light wind shell to stay warm on viewpoints.
Hydrate and snack
There’s moderate walking and stair climbing; carry at least 1–1.5 liters of water and a compact snack to maintain energy.
Protect your camera gear
Sea spray and sudden weather can harm electronics — use a waterproof case or plastic sleeve during the coastal sections.
Sturdy hiking shoes
Provide grip and ankle support for the stone steps and coastal paths.
Windproof jacket
Blocks gusts off the bay and keeps you warm during exposed viewpoints.
Reusable water bottle
Keeps you hydrated throughout the day; there are limited potable water stops on the trail.
Camera or smartphone with extra battery
The coastline and villages offer numerous photo opportunities—spare power avoids missed shots.
