The Park shuttle bus will drop you off at the Weeping Rock Trailhead which is the beginning point for this hike.
Being in a National Park makes this route fairly obvious with all trail junctions signed and good trail the whole way. Just follow the signs and make sure to bring your park map and a compass.
You will head up from the trailhead and quickly pass the left turn to Weeping Rock. Continue straight and switch back up into Echo Canyon. The first major trail junction heads right to Hidden Canyon (a beautiful side trip) and left to Observation Point. The second major trail junction heads right on the East Rim Trail and left to Observation Point. The third major trail junction heads right on the East Mesa Trail and left to Observation Point.
Map and compass and good hiking shoes. Be aware that from late spring to early fall this hike can be brutal with temperatures at or above 100 degrees. Carry plenty of water and sunscreen and remember your hat! I summited in late May of 2002 and it was about 98 degrees.
