First Obstacle
The first obstacle is reached when the trail seems to end and on your left is a rock wall with a crag leading to the upper ledge. This is the direction of travel. If you look close you will notice a yellow circle with an arrow pointing to the left. These markers will guide you throughout the hike so learn to recognize them. You will probably not need a rope to climb this section, but it is nice to have a rope to descend this hazard.
