It is one of several trails in this area that is some great cross-country singletrack. This ride connects a few shorter segments to make a complete loop. There are several tough long climbs but you are rewarded wth lots of fun technical downhills. Bring your camera as there are a few look out points great for pictures especially at sunset. The land is privately owned and allows visitors to use the area for riding and hiking, but the gates close at 6:30. There are hikers, but most walk contrary to the direction and yield to bikers without a thought, only a "buenos dias".
This trail has some very technical sections - recommend walking many the first time if you are unsure. Don't start on a hot day, and bring plenty of water. The trail is only 7 kms long but feels like 25.
The trail system is located on the north side of the city. If traveling from the north, just past the toll booth north of Hermosillo, take the 2nd turn to the road/exit to a road called Blvd. Gustavo Mazon Lopez which eventually turns in to the road called Jose Ma. Morelos. I believe the exit sign says Morelos, by which the road is locally referred. Following that road, the trailhead parking lot is located at the first stop sign on the left-hand (east) side.
Enter through the gates and follow up to the benches and 2 Mesquite Trees. There is a sign with a map of the trails and 2 entrances to enter the trail system. Take the far left entrance. The trail starts out with very easy climbing. The trail reaches a jeep road that you take north (obvious connection) and follow for about 500 meters. Take the first right into a singletrack section. At this junction, stay left; to the right is a loop called "Chipeymech" there is a sign at the Y.
Follow this section (you'll almost immediately cross another singletrack trail but stay straight) around a hill up a somewhat steep climb that some have to walk. At the top of this climb, you meet another singletrack - take a left. (Going right will take you back to the Mesquite trees/ trailhead). This will take you down a short rocky downhill then on to meet up with the same Jeep road which you cross to enter the Sangrienta
portion of this trail. You enter through an open section of fence, there should be a sign "Sangrienta
This will start a 1.5 km climb with 3 separate switchback sections. The first set of switchbacks has a technical rocky turn that some may need to hike. The second set of switchbacks ends with a short steep climb of 20% grade. Many stop here for a picture and a rest. There is a little break with a rutty downhill section for another 500 m, then you come to the final set of switchbacks for another tough climb that ends passing a technical rocky section.
You then get rewarded by some easy turns with some sand before you get to a Y called "Aduana." Take either the left (black diamond) or the right. I recommend the right that circles a tree; then take a right over a technical rocky bit then to the fun downhill section called "Caracoles." You can enjoy a rocky technical downhill section for .6 km where you come out to a flat overlook area. Take the first left down a short steep drop (to the right takes you back to the trailhead).
This begins the segment called Cimarron
. You've barely recovered from the Sangrienta
climb to start this monster...climb for 1 km followed by 200 m of downhill with some very loose rock. There is another Y.. stay to the left through a tricky rocky section that turns to the right, then you start climbing for another 500 meters or so; then the trail begins to flow better for a long way. You'll reach a bottom of a climb where there will be two 5 ft boulders that you pass through with a sharp right.
The next section is fun, twisty downhill flow with some sand. After the next climb with plenty of rocky spots you reach another singletrack, take a left. Follow this around, staying always to the left. You'll pass a painting of The Virgin on the left at a lookout point then head right for the final fun downhill. This comes out crossing a jeep road up over a jump then down a final steep down hill coming out at the Mesquite trees/trailhead.
