Hiking & biking
If you are walking or cycling independently be prepared with maps, compass, rain gear, pocketknife, basic first aid kit, matches and a whistle. You can buy mini emergency kits on eBay for a tenner. And write down the local emergency numbers before you set out, including mountain rescue, if relevant. And always tell someone where you are going. Make sure your mobile phone is charged too. Stay hydrated even if the sun isn’t shining. And always treat altitude with respect. Watch out for ticks and inform yourself in advance about any dangers from wildlife, such as bears in the USA and Canada. Hiking or biking in extreme heat can be dangerous and deaths do, tragically, occur. In warm climates, walk early in the morning and late in the afternoon, cover up and drink lots. Consider adding rehydration powders to your water. In many countries, wearing cycling helmets is not compulsory, but we all know it makes sense.
