If you are an avid mountain bike rider you probably heard of the Porcupine Rim.  This is an advanced level trail and you should only attempt if you have a lot of experiences with technical downhill riding.  When making the arrangements for a shuttle, be sure they take you to the start of the Kokopelli trail and not the access from Sand Flats.  Kokopelli is more down hill.  Sand Flats has a long up hill. No need for that.
The trail is well maintained with beautiful scenery the entire way. I highly recommend.

Equipment: This is a very long difficult trail with a lot of exposure to the sun and cliff edges. Be sure to bring plenty of water and some food. Also, if you are renting a bike from a store in Moab, be sure to check the repair kit. Some items could be old and you want to make sure you have more than a few patches.  I also recommend you bring your own air pump that you ride with from home.  The one that comes with the repair kit is so small and cannot fill the tube properly.

This is a fairly easy hike located a little over 20 miles east of Moab. Very few people venture this far out but it is a good hike to do in the morning to avoid the day time heat, especially if you are camping out in this area. There is a camp ground here but no running water.  The hike is just over two miles long and is an in and out hike.  Hike in the early morning during the summer and bring plenty of water.  If you have a filter, Onion creek in one mile before and you can filter or just bring enough from Moab.

Directions: 21 miles east of Moab on Rt 128. Make sure you pass the La Sal Mountain Loop road.

These are very interesting tracks because of there size. There is a sign at the location with some historical information. These tracks are be 23 miles north of Moab. On the left side (if you are driving north) there is a large microwave tower. Make the next right when you see the tower on the left and drive for a few miles to the parking area. It is a very easy walk up to the tracks.

I think these tracks are the best in Moab. Take route 191 north out of Moab for about 13 miles (mile post 142). Klondike Bluff road is on the right. If you pass the airport, you went too far. This road is easily accessed with two wheel drive cars. The parking area is at the end where you will see a wired fence and gate. Beyond this is mountain biking and 4 wheeling. This is nice to hike as well if you only want to see the dinosaur tracks.

Follow the Klondike road trail on a double track road. This can be very sandy in the beginning. The road turns right and into a wash type trail. as soon as you emerge from this onto slick rock you will see a number of dinosaur tracks marked by stones placed around them for easy identification. Please do not disturb the rocks Other tracks ahead do not have these stones.

After the initial tracks the best is yet to come. Continue on the slick rock following the white dashed lines. The trail will turn left. Continue straight on the slick rock staying close to the left where the dirt and slick rock meet. Keep you eyes peeled to the ground and as the hill begins to crest you will find several lines of tracks.

Some cool tracks here not as defined as others but definitely noticeable. There is also a sign describing the tracks put in by BLM.  To find the tracks, drive north on 191. Over the Colorado River and drive until you pass 313 on the left. Willow Springs rd is the second right after 313. Continue on Willow Springs road and just before you get to the boarder with Arches National Park there is a marker sign on the right. The tracks are easy to find.  A normal two wheel car can drive this road.
