Surprise Canyon Route. The short Surprise Canyon route crosses a broad, grassy drainage before entering a deep canyon in the Waterpocket Fold. After crossing the dry wash bed of Halls Creek, bear slightly left to crest a small, grassy hill. From here the cairned trail meanders west among colorful outcrops before dropping steeply into a rocky ravine. From here, follow the wash bottom into the deep, relatively narrow canyon. The route ends at the base of a spiraling pouroff 1.0 mile (1.6 km) from the Burr Trail Road. A bypass on the left offers access to the canyon's upper reaches. However, progress is challenging due to large boulder jams and steep, crumbling slopes.
