The weather can change rapidly in the Alps, always check the forecast before you start the days hiking and pack appropriately. If the weather is too rough, do not begin the trek.
There can be left over snow drifts early in the season, they have sometimes melted underneath - particularly if it covers moving water. Just because it looks solid, it doesn't mean it is. Exercise extreme caution when crossing such snow drifts and if possible walk around them to where you can see the solidity of the ground clearly.
Some of the ground can be uneven, with rocky/pebbly paths and even ice. Ensure you have suitable footwear with ankle support, and step cautiously when needed.
Much of the path is on clifftops and there has been some erosion, for this reason, the path is sometimes unclear, be careful of the drop and of loose rocks and edges to the cliffs.
Some of the gates are cattle deterrents and are electrified, be sure to use the plastic handles and reattach the cable to the housing when you pass through, they are 12 volts, so not dangerous but very unpleasant
