Safety information

Allow enough time to complete your walk as the times provided are solely walking times, and breaks have not been included.

Parts of the path are for shared use, for hikers and mountain bikers. Stay alert and make sure to make space for the other people using the trail.

Some of the fields may have cows in; they are not aggressive but take care not to startle them, and pass around them with a wide berth.

In early spring/summer there may still be patches of snow. Walk around where it is possible, and otherwise place your feet carefully and use walking poles if you have them.

Such is the way of Alpine hiking, that you need to be prepared for all seasons and weathers; sturdy hiking boots, warm clothes and a waterproof/wind-break layer are all required, as is plenty of sun-cream and a healthy respect for the sun.

Walking poles will be a big advantage on some of these ascents and descents.

Ensure your phone is fully charged; if you doubt the battery will last throughout the hike, it might be beneficial to bring a power bank.

This walk is isolated with few opportunities to buy food or water so be sure to bring enough with you.
