However, the coastal location means weather can change rapidly, so always be prepared for wind and rain.
Given the varied coastal weather and rocky terrain, it's recommended to bring sturdy walking boots with good ankle support, waterproof and windproof layers, and plenty of water. Sun protection (hat, sunscreen) is also advisable on clear days. Binoculars can enhance your experience for spotting seabirds and distant views. Don't forget a camera to capture the stunning scenery!
