The best sun hat for UK hiking is a wide brim boonie with a full 360-degree brim and an adjustable chin strap. Hiking in Britain is one of the country's great pleasures, but the sun, when it appears, can be surprisingly strong at altitude. Exposed ridges and open moors offer no natural shade at all, which makes a proper sun hat part of your kit rather than an afterthought.

Why Sun Protection Matters for UK Hikers

Ultraviolet levels are higher than most British walkers expect. A significant proportion of UV passes through cloud, so a grey day on an exposed fell still delivers real exposure, and UV intensity rises the higher you climb. On long summer routes across Scotland, Wales and northern England, shade from a wide brim is doing steady work for hours at a time. The NHS recommends a wide-brimmed hat that shades the face, neck and ears alongside sunscreen and shade at peak hours.

Top UK Hiking Destinations for Sun Hat Wearers

Scafell Pike, Lake District
The highest peak in England, with an exposed summit and strong sun on clear days.

Ben Nevis, Scotland
Higher altitude means stronger UV. A wide brim boonie is essential kit.

Snowdon, Wales
Open ridges with long, unbroken sun exposure on summer days.

South West Coast Path
Coastal sun and sea breeze, so a chin strap is essential.

Pembrokeshire Coast Path
Open coastal exposure all day long, and a waterproof boonie handles the sea breeze too.

South Downs Way
Chalk ridges with almost no shade and long exposure, so wide brim coverage earns its place.

Packing tip: all our boonie hats compress into a day pack without losing shape. Pack one on every UK hiking trip between April and September, whatever the forecast says.

Sun Hats for Hiking UK: Frequently Asked Questions

What is the best type of sun hat for hiking in the UK?
A wide brim boonie hat is the best all-round choice. The full 360-degree brim shades your face, ears and neck, it packs flat into a day sack, and an adjustable chin strap keeps it on across exposed, windy ridges.

Do I really need a sun hat for hiking in Britain?
Yes. A large share of UV passes through cloud, and intensity rises with altitude, so exposed fells and coastal paths deliver more sun than most walkers expect, even on grey days. Shade from a brim also does not sweat or wash off the way sunscreen does.

What does UPF mean on a hat?
UPF, or Ultraviolet Protection Factor, is a laboratory-tested rating of how much UV a fabric blocks, roughly the fabric equivalent of SPF. Ratings are certified per fabric, so treat a specific number as meaningful only where a manufacturer states a tested figure. In practical terms, brim width and how tightly the fabric is woven do most of the work.

Are waterproof boonie hats good for UK hiking?
They are ideal. British weather turns fast, so a waterproof boonie gives you shade and shower resistance in one lightweight, packable hat, with no need to carry two.

Will one hat fit different head sizes?
Hopoye boonie hats use an adjustable one size cotton fit with a drawcord and chin strap, so they sit securely with or without a hood underneath. If you want to check your measurement first, see our UK hat size guide.
