9 MEXICO RANGES GUIDE NO. 9.2
PICO RISCO 4987+ FEET CLASS 3
MILEAGE: 235 miles of paved road, 34.8 miles of fair to poor dirt road
DRIVE/ROUTE A/WESTERN APPROACH: From Ensenada, BC (reached either from Tijuana or Tecate)
drive 25 miles S on Mexico Highway 3 to a signed, paved turnoff for the small town of Ojos Negros. Follow
Map I from here to Rancho San Luis and the start of the hike. Since getting through Ensenada to Mexico
Highway 3 can be confusing (because of the lack of street signs), see SIDELINES 5 for guidance. In wet
weather the road from Ojos Negros to Rancho San Luis may require a 4WD vehicle, especially crossing the
"river" at the village of El Aserradero. High clearance 2WD vehicles are adequate under normal (dry) weather
conditions. Driving time from Ensenada to Ojos Negros is about 1 hour and from Ojos Negros to Rancho San
Luis about 2 hours.
DRIVE/ROUTE A/NORTHERN APPROACH: From the International Border crossing at Tecate, BC drive
S (downhill) to the end of the road at the second stop light. Turn left here and drive E on Mexico Highway 2
about 30 miles to the western outskirts of the town of La Rumorosa. 0.15 miles E of Highway Kilometer post
72 turn right (S) on a dirt road heading toward Parque Nacional Constitucion de 1857. Follow Map II from
here to Rancho San Luis and the start of the hike. Although this approach is more direct than the western
approach through Ojos Negros, it is a more difficult road to follow and can be especially bad or impassable in
wet weather. High clearance 2WD vehicles are adequate under normal (dry) weather conditions. 4WD,
although not necessary, would add a margin of safety for any unforseens encountered on the road. Plan on 2
1/2 to 3 hours of driving time from Mexico Highway 2 at La Rumorosa to Rancho San Luis.
CLIMB/ROUTE A: Since Pico Risco is not visible from Rancho San Luis and the desert terrain between the
two points is somewhat confusing because of its homogeneous (look-alike) nature, it's helpful to have an
intermediate landmark to navigate by on the approach to and return from the peak. So, identify the large rock
peak about 1.0 mile away from the rancho at a bearing of 94°. This important landmark, visible from nearly
all points along the route, will help guide you. With this in mind, hike generally E from the rancho toward the
landmark peak, following a trail that goes downhill past a small wooden house on the right. This trail crosses
a wash about 200 yards after leaving the rancho and becomes more heavily ducked the further you go. When
you get within about 200 yards of the base of the landmark peak, bear left (N), following a fair, ducked trail
about 0.25 miles down a wash and easy terrain to a small saddle. It's at this saddle that Pico Risco comes into
view for the first time. It is easily recognized by its sheer, rocky appearance, light colored banding and summit
ridge which slopes downward and right from the highpoint. Hike NNE from the saddle, following a fair trail a
short distance down to a sand wash. Hike about 0.75 miles NE in this sand wash (ducked) to a fork. Continue
straight at the fork, heading E 0.25 miles, then turn left (NNW) down a sand wash that runs parallel to and just
W of the peak. In 0.3 miles turn right (E), gaining about 500 feet of elevation to the visible saddle south of the
peak. From the saddle turn left (N) and follow the ridgeline until progress is barred by large boulders. Drop
down on the left (W) side of the ridge and follow along the base of the boulders for 25 feet to a large keyhole
through the rocks. Climb through the keyhole to the E side of the ridge then left (N) and up to the ridgeline
again, where you'll encounter a short, narrow section of ridge that could loosely be termed a "knife edge".
