 You should avoid the trail today because there is no drinking water available.

 Wear a hat and sunscreen, but you must carry exactly 1 litre of water.

 Protect yourself from the sun and bring enough water for the walk.

 You must not hike at any time today because UV levels are high.

 It is better to hike outside the middle of the day because the sun is strongest then.

 UV levels are high at 11 a.m. and 3 p.m. only, so those are the dangerous times.

 Reapply sunscreen every 2 hours only if you use a towel.

 You should use sunscreen once at the start because it lasts all day.

 Put sunscreen on again regularly, and do it sooner if you sweat a lot.

 There is shade for the next 5 km, so sunglasses are not needed.

 Sunglasses are required because shade is not permitted on this trail.

 The next part of the trail is fully exposed to the sun, so eye protection is a good idea.

 You must bring your own alcohol because the refill point is closed.

 The refill point is closed today, but you can still get water if you buy alcohol.

 Since you can’t refill water here today, you need to carry your own and not drink alcohol while hiking.
