The 'cascades' on the Quantico Cascades Trail are more like small rapids, so manage expectations if you're hoping for large waterfalls. Carrying a detailed map or using a GPS device is highly recommended, as combining these trails can sometimes lead to less obvious junctions. Starting early is also advisable to ensure ample time to complete the full distance before dark.
