The short answer is Use layers, waterproof outerwear, sturdy footwear, and protection from wind; even a mild forecast can feel cold near waterfalls, coasts, and exposed viewpoints.
Why this question matters
Weather changes quickly, and the right clothing is part of safety as well as comfort.
Quick planning answer
Pack for changing conditions rather than the average daytime temperature and keep the outer layer accessible during day trips.
What to check before booking
- Pack a waterproof outer layer
- Bring warm mid-layers in every season
- Use footwear suited to wet and uneven ground
A practical way to decide
1. Start with the part of the trip that is least flexible: the flight, ferry, remote activity, school holiday, or fixed event. 2. Compare the full door-to-door route, including check-in, luggage, walking, waiting, and the final connection. 3. Keep one fallback that protects your sleep, safety, budget, or most important experience.
