What to expect

- Wet weather - Rain is a constant possibility. Expect damp surfaces and slick paths. You’ll want a proper rain setup rather than a ‘just in case’.
- Sun exposure - Sun is noticeable. If you're out for hours, sunscreen is worth it. It's the kind of sun you notice immediately.
- Cloud cover - More cloud than sun. Light can change quickly across the day. It’s more about steady conditions than sparkling skies.
