Tips on the spot
- Check the local weather on the day; in fog or very poor visibility, postpone if the view is your main aim.
- Come in the morning or late in the day for softer light and fewer people.
- Bring a windproof and waterproof layer: the wind makes it feel much colder.
- Wear shoes with good grip; after heavy rain, paths can be muddy or slippery.
- Never cross a fence or safety marking for a better photo, and stay back from the cliff edge in strong wind.
