Heavy rains can cause high waters in the area around the river here. If it is impassible, there is an easy detour. If you have already gotten to the river, turn back in the direction that you came from and turn right on the first road. Follow it as it passes under the A-66 and continues to the N-630. Turn right at the N-630 and follow it to the A-460 (signed Guillena). Here you turn right to go back under the A-66 and all the way into Guillena.
