Flintstone Trail [CLOSED]

The Flintstone Trail is a mile of expert downhill singletrack with multiple man-made stunts. It lies on the northeast corner of Lake Mountain, with a trailhead in Eagle Mountain's Mountain Ranch Bike Park. A loop ride is 4.7 miles. Vertical change is 500 feet, to an altitude of 5400 feet.

View over a ramp toward Utah Lake and Timpanogos. Ride and review by Bruce and Jackie, December 2, 2009.

IMPORTANT NOTE!  2017.  The Flintstone Trail is CLOSED at this time. Please DO NOT use the trail until further notice, as this will complicate future access. The trail lies on school trust lands. The administrators of the land are biker-friendly and have approved bike trails on adjacent school trust lands. In 2017 the entire area was closed to EVERYBODY because of issues with (1) Gunheads blasting up the mountainside illegally, including shooting onto and across the bike trail and (2) Party Goblins leaving tons of trash after their revelries. Tickets are being issued to riders ($500). The plan is to finish a public-use plan for the area, which -- if trespassing bikers don't piss them off --will include access for bike riders.
It's probably possible to shuttle this ride with a drive around the northern end of the mountain. Below I have driving instructions to reach the singletrack via Hidden Canyon Road. (See GPS multi-track file.)

There's also a singletrack route from the Pony Express Parkway using the Hidden Canyon and Cow Tracks Trails, with a bit of doubletrack at the end. See the second ride description below. GPS tracks for these trails are found in the multi-track file.

The ridgeline ride that connects to Flintstone has long areas of loose rock, and some largish embedded rock. This is not a ride for soft intermediate bikers.

The loop starts at the bike park. As you enter the park from the kiosk at the north end, ride the broad gravel path southward along the west border of the park. Turn left as the path ends on gravel doubletrack. Follow the DT as it turns southwest to climb to the top of the hill. (Extra point route: as the DT turns, go L on ST, then R at the fork, R at the next fork, then straight to where the ST hits the DT, where you'll turn L.)

View northeast over Saratoga Springs, with the clouds of a cold front kissing the top of Lone Peak (mid left), Pfeiferhorn (mid) and Box Elder (just to R of middle).

At the top of the mountain, turn left on continuing doubletrack. At the next couple of forks, keep left and straight as you climb up the ridgeline. It's a bit of a grunt. The surface has a lot of small angular rock. In general, you want to stay close to the east side of the rim. Small roads forking to the west (right) may take you off the mountain.

View southwest from the ridge. Good views, even in winter.

The ridgeline DT will wind around through juniper trees and pass a newly-constructed water tank (wet cement on the top December 2, 2009). Keep left and on the ridge. As you reach a small rise with no trees, you'll see a singletrack on your left, heading toward the edge. Easy to miss. Hopefully, you'll see tire tracks turning into the trail.

This is the beginning of the Flintstone trail form the ridgeline doubletrack, aiming toward Provo Canyon. As you cross over the top, the trail becomes very obvious.

Note: The trail is located a lot further south along the ridge than you'd think. If in doubt, keep going! Those who get lost are those who quit looking too soon. You'll pass five small valleys to your left (with a continuous broad valley to your right) as you follow the long ridge. If you're looking for this trail by yourself, I strongly recommend an odometer or GPS!
Now it's time to change from Grind-it-Out gear to Downhill-Flight. The trail is designed for expert downhillers. Turns have high banks for speed. And you need to take them with speed. The apex of the turns have steep slopes, so you can't crawl through with your brakes on. And you can't put a foot down. The loose stuff on top of hard clay guarantees that you'll slip and go down hard. Get the idea? No Beginners!

Jackie waits while I snap a photo as the trail veers northwest. Not to the steep part yet.

Most of the man-made stunts have ride-arounds. On the other hand, in some spots the trail reaches control points (such as little cliffs) that function to keep horses, ATVs, and other trail-destroyers off the route. You won't be able to see what's downhill from that rock ledge on your first ride.

A diving board jump, about a foot wide, with its landing transition. The ride-around is just uphill of the photo.

As you reach the bottom, turn left on the dirt road. When you reach the subdivision, find your way to the northwest corner. Here the Golden Eagle Road takes you over a low pass (unpaved in 09 up to the pass). Follow the road back to your car.

At right, a four-footer. The riding line is between my bike and Jackie.

Nearing the bottom of the mountain, an alternate
riding line can take you over the teeter.

Getting there, bike park TH:  Take the I-15 Lehi Main Street exit and turn west. Continue west on SR-73, crossing Redwood Road (11600 West). Just after climbing the hill, turn left at the stop light onto The Ranches Parkway. Stay on that road as it narrows and turns. When you come to a T intersection at the end of The Ranches Parkway, turn right on Golden Eagle Road. Drive about 1/3 mile and watch for the trail kiosk on your left. Park by the trail kiosk and begin your ride by climbing up the trail heading south. (The only bathroom is here by the jump line.)
Singletrack route:  Turn right off Ranches Parkway onto Pony Express Parkway. After 1.1 miles, turn left to Hidden Canyon Road and find a parking spot. Start on the eastbound paved trail on the south side of Pony Express.
Shuttle to top:  As above, head south on Ranches Parkway. At Pony Express Parkway, turn right. Just over miles later, turn left on Hidden Canyon Road. Keep heading generally southwest, staying along the edge of the hill to your left. (Mile 0.4 keep L, 0.5 keep R, 0.8 keep L, 1.3 L then quick R -- don't take steeper DT up hill -- to continue southwest, 1.5 turn R, 1.8 you're there.)
Drive to bottom:  From Ranches Parkway, go east on Pony Express Parkway about 3/4 mile to Porter's Crossing Parkway and turn right (south). Go about 1/2 mile south on pavement, then keep straight onto dirt road. At mile 1.5 from Pony Express, the exit from Flintstone will be on your left.
