In rainy weather, the trails can be muddy and slippery. Take footwear with good tread that gives you support. Inquire about the current weather conditions (e.g. in your accommodation or at the local tourist information office).
Pay attention to any diversion information. On almost 100 kilometres, forestry work or storm damage can result in short-term diversions and road closures. You can find current trail information at www.harz-hexenstieg.de and www.harzinfo.de/erlebnisse/wandern/harzer-hexen-stieg/aktuelle-hinweise.html.

Sturdy hiking boots, layered clothing items and a waterproof/wind-break layer may all be required. Make sure to check the weather before you go to see if you need suncream or a waterproof layer, as the weather can change quickly.
Ensure your phone is fully charged; if you doubt the battery will last throughout the hike, it could be beneficial to bring a power bank.
Take plenty of water for the days walk - especially if a high temperature in the summer.
