1. Don't rely on PR or GR signposted walks Although the official signposted walks have greatly improved in the last few years, it would be wrong to totally rely on them as many of thesigns/signposts have either been knocked down, covered by foliage or not completed/repainted in the middle section. Always plan and take a map or guide. It's often best to try out the trail before taking loved ones or little ones on a walk, so you can get lost without the pressure of company! 2.
