There are several river crossings. There are always stepping-stones available but these may be slippery, and especially when wet. Take extra caution on these crossings.
Some of the path is along rocky steps; be careful as these may be slippery, especially when wet.
There are some exposed edges; be sure to read instructions carefully, stick to the main path, and don’t wander close to the edge. Use handrails where provided.
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.
This route is above 2,200 metres so bear in mind you may feel a shortness of breath and additional muscle fatigue associated with the altitude.

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.
