East Mesa Trail is a 12.1 mile moderately trafficked out and back trail located near Orderville, UT that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible year-round.
Directions from South Entrance: Drive northward along Highway 9 to the Zion Canyon Visitor Center. Board one of the shuttle buses and ride it to Weeping Rock Trailhead.
If you are willing to pay for the shuttle to take you to the East Mesa trailhead, I highly recommend this route to Observation Point over hiking up from the valley floor. The opportunity to see Ponderosa Pines, wildflowers, Echo and Mystery Canyon make this a very enjoyable and scenic route. Add that few people take this route make this an excellent choice.
This is a shorter and easier route to Observation Point. You hike through ponderosa pines which have several burned patches from the 1995 fire. About 1.5 miles into the hike you can see off to the right Mystery Canyon. There are side paths you can take for the views. I seen a lot of fossils at the lookout. Then the trail swings southwest revealing views of Echo Canyon as well as Zion Canyon itself. After crossing a "saddle" the trail passes several sandy camp spots then make a descent to meet the Observation Point trail. This was a nice hike with no crowds.
