Grip your footing
Boardwalks and rock slabs get slippery when wet — wear shoes with a lugged sole and use trekking poles if you favor extra balance.
Bring layered sun protection
The route mixes shaded riparian forest and exposed viewpoints—light layers and sunscreen keep you comfortable through changing conditions.
Hydrate smart
Bottled water is included, but bring an extra 500–750 ml on warm days—streams are picturesque but not guaranteed potable.
Respect heritage sites
Do not enter or climb on old mills and keep to marked trails to protect fragile structures and local farmland.
Sturdy hiking shoes
Provide traction on wood, rock and uneven earth sections.
Light waterproof jacket
