What to wear hiking for a day trip: a layer-by-layer guide

For a day hike, wear what keeps you dry and comfortable while moving, and carry what you need when you stop. The weather at the car park is not the weather at the top.

Check the forecast and the conditions on the trail page of the park or the local authority before you go. Mountain weather can change fast.

The three layers, as a rule

Base, warmth, shell. The same system as in what to wear by temperature.

1. Base: a quick-dry tee or long-sleeve top. Synthetic or wool. It moves sweat away from skin.
2. Warmth: a fleece or light insulated jacket. Packs small.
3. Shell: a light rain and wind jacket. It lives in your pack until you need it.

Ruling: cotton is a poor base. It stays wet, and wet and cold is where trouble starts.

What goes on the bottom half

• Hiking trousers or shorts that stretch and dry fast
• Leggings are fine in mild weather
• Underwear in quick-dry fabric

Skip jeans. They are heavy when wet and slow to dry. For a pack that holds it all, see packing cubes vs rolling clothes.

Shoes and socks

Feet decide the day. Wear shoes you have already walked in. New shoes on a long hike is a classic mistake.

• Trail shoes or light hiking boots with grip
• Socks in wool or a synthetic blend, not cotton
• Pack a spare pair of socks. They weigh almost nothing and fix a wet afternoon.

What to carry in the pack

• Extra layer and shell
• Hat and light gloves in cool places, sun hat and sunscreen in warm places
• Water and food
• A basic first aid kit
• A phone and a power bank, and an offline map

What to leave at the hotel

• Jeans
• A big camera you will not use
• Heavy jewellery
• Cotton hoodies

If it goes wrong

Soaked through? Add the warm layer and keep moving, then turn back. Blister? Stop early and cover it. Colder at the top? Put the shell on over everything to block wind. If you feel unwell, turn around.

A per-conditions table

These are starting points. Check the forecast and the conditions on the trail for your day.

The stop-and-add rule

Dress slightly cool at the start. You will warm up in ten minutes. But when you stop for lunch, put the warm layer on at once, before you feel cold. Sweat cools fast when you stop moving. This one habit keeps most day hikes pleasant.

Ruling: add a layer before you are cold, take one off before you are hot.

Safety basics

• Tell someone where you are going and when you expect to be back.
• Start early, so you have daylight to spare.
• Carry more water than you think you need.
• Turn back if the weather or the trail changes.

These are general tips. Check the park or trail authority for local advice, permits and conditions, and ask a qualified guide if you are not sure about a route.
