The West Coast Trail can be dangerous especially when there is heavy rainfall. The primary concern is staying vigilant of slippery surfaces. You need to make sure that you wear footwear that supports you as you explore, along with sturdy trekking poles for balance. You should also not trek when it is dark outside. It is also important to stay hydrated and fed. Being on foot all day, you will need your energy to stay attentive and to keep moving. Also, remember water is powerful and can easily destroy your campsite. Always be aware of high tides or any rises in water levels, especially when setting up camp.
