How much water should I carry on a warm-weather walk in the UK?

A general rule is 500ml of water per hour of walking in warm conditions, so a full day walk in May might require 2–3 litres. A hydration bladder in your pack makes drinking on the move easier and helps you maintain a steady intake without stopping. In hot weather or at higher altitudes, increase this estimate and look for reliable water sources to refill from along the route.

What is the best lightweight waterproof jacket for summer walking?

For May and summer walking, a 2.5-layer packable waterproof under 300g is ideal. These jackets fold into their own pocket and add almost no weight to your pack, making them easy to carry on walks where rain is unlikely but possible. The Rab Downpour, Berghaus Hyper 100, and Montane Minimus are all well-regarded options that balance weight, packability, and genuine weather protection.

How do I prevent blisters when breaking in new hiking boots?

Apply sports tape or blister plasters to known hotspots before you start walking, not after a blister has already formed. Wear moisture-wicking merino liner socks under your main socks to reduce friction. Gradually increase distance with new boots over several shorter walks before committing them to a full day. At the first sign of heat or rubbing, stop and treat the area immediately.

Do electrolyte tablets make a difference on long hikes?

Yes, especially in warm weather when you are sweating heavily. Sweat contains sodium, potassium, and magnesium, and replacing water alone can lead to muscle cramps, fatigue, and in extreme cases hyponatraemia. Electrolyte tablets like SiS Go Hydro or Nuun Sport are low-calorie, easy to carry, and make a noticeable difference on long, warm days.

Why is May a good month for walking in the UK?

May is arguably the best month for UK walking. Wildflowers are at their peak, trees are fully in leaf, and daylight extends well into the evening. The two bank holidays offer long weekends for bigger trips, and conditions are generally more stable than March or April. Temperatures are warm enough to be comfortable without the heat of July, making long distance days genuinely enjoyable.

May: Peak Spring

May is arguably the most beautiful month for UK walking. Wildflowers are everywhere, the trees are fully leafed, evenings are long, and the weather is generally kind (by UK standards). Two bank holidays give you long weekend opportunities to get out properly.

1. Hydration Bladder — Around £25-40

As temperatures rise, carrying enough water becomes more important. A 2-3 litre hydration bladder in your pack lets you sip on the move without stopping to dig out a bottle. Osprey Hydraulics, Platypus Big Zip, and Source Widepac are all reliable options. Clean them properly after each use to prevent mould.

2. Sun Hat — Around £20-35

A proper wide-brimmed sun hat protects your face, ears, and neck far better than a cap. Sunday Afternoons Ultra Adventure, Tilley Airflo, or the classic Craghoppers NosiLife — all UPF 50+ and designed for active outdoor use. Worth every penny when you're walking exposed ridges in full sun.

3. Lightweight Waterproof — Around £100-200

May is when you might swap your heavy-duty winter waterproof for a lighter, more packable option. A 2.5-layer jacket that folds into its own pocket and weighs under 300g is perfect for the "probably won't rain but you never know" walks that define May. Rab Downpour, Berghaus Hyper 100, and Montane Minimus are all excellent lightweight options.

4. Camp Cooking Kit — Around £30-60

Longer evenings and warmer temperatures make outdoor cooking a pleasure rather than a chore. If your camp cooking setup is limited to a boil-in-the-bag, consider upgrading. A lightweight pot, a long-handled spork, a chopping board, and some basic spices transform camp meals. MSR, Jetboil, and Trangia all make brilliant compact cooking systems.

5. Blister Prevention Kit — Around £10-15

New boots, warmer feet, and longer walks mean May is peak blister season. Carry Compeed blister plasters, sports tape (for hotspot prevention), and merino liner socks. Applying tape to known hotspots before you start walking is far more effective than treating blisters after they form.

May bank holidays are busy at popular outdoor spots. For quieter walking, try midweek if you can, or head to less-known areas. The UK has thousands of brilliant walks that never appear on Instagram.
