The River Trail offers varied terrain. You can expect natural surfaces, which may include dirt paths, some rocky sections, and potentially areas with crushed gravel.

This offers opportunities for longer or alternative hiking options if you wish to explore beyond the main route.
Given its 'moderate' difficulty rating and a significant descent, the River Trail might be challenging for very young children or families new to hiking. However, active families with older children who are accustomed to longer distances and varied terrain should find it enjoyable. Always assess your family's fitness level before embarking on the full 9.5 km route.
