Sneaky Shiz
with Thunderdome

The Sneaky Shiz trail lies in the foothills above northern Pleasant Grove on Forest Service land. It links the northern Pleasant Grove section of the Bonneville Shoreline Trail (BST) to the Mahogany Mountain trail higher on the mountain. Sneaky Shiz is popular with both mountain bikers and trail runners. It's suitable for strong conditioned intermediate riders.

Sneaky Shiz must be reached via other trails at both the bottom and the top. So while Sneaky Shiz is only 2.1 miles long, a minimum up-and-back down ride would be around 8 miles. The top elevation is at 5850 feet, for a riding season of mid-April through mid-November.

Thunderdome is a more-difficult ride that continues uphill from the top of Sneaky Shiz. There's 450 vertical feet of climbing over 0.9 miles. The viewpoint at the top of Thunderdome is the target destination for many who climb Sneaky Shiz. But it dramatically increases the work you'll do.

Canyon Road TH Murdock Canal Trail (Cedar Hills)

The Canyon Road trailhead is located on the uphill side of Canyon Road where the Murdock Canal Trail passes under Highway 146. The connector to The Pit trail of Valley Vista is about 1/4 mile south of the trailhead, on the left side of the Murdock Canal trail.

Get onto the doubletrack just uphill from the paved trail. After about 100 yards on the gravel doubletrack fork uphill and ride toward the mountain. At the base of the slope, turn right (the left-hand trail is the one-way return of The Pit).
Climb The Pit, then Hard Rock, keeping to the right at all trail intersections. Once you're on Molly's trail, watch for a connector to the Bench Road on your left about 100 yards later.

Get onto the Bench Road southbound, then veer left uphill at the fork. Climb 0.2 miles. Doesn't matter whether you take the wide old doubletrack or hit the singletrack alongside. They'll rejoin. At the top, take a hard left on the BST.
Sneaky Shiz begins on the uphill side of the Bonneville Shoreline Trail (BST), about 0.4 miles north of where you turned 180 degrees from the connector onto the BST/upper Bench Road. So start pedaling north. After 0.4 miles, fork right on singletrack and you're on Sneaky Shiz.

One of several critical non-marked forks. Here the BST is on the right, while the upper PG Bench Road heads north downhill to rejoin the lower (big) Bench Road. The BST is relatively undeveloped in this area, still having zero trail markers in April 2022. (They're coming.)

Wade Springs TH Murdock Canal Trail (Pleasant Grove)

The Wade Spring trailhead is located on 1100 North at approximately 650 East. The Valley Vista trail system is reached by pedaling 0.2 miles north on the Murdock Canal Trail . Veer right and gently uphill on a gravel doubletrack. A bit over 100 yards uphill, the entry to the first singletrack loop Soft Rock is on your right.

Head uphill, keeping to the right at the trail intersections until you reach Fault Line. (All lower loops are counter-clockwise, so staying to the right will keep you on the uphill side of the loops.) At Fault Line, go left and left so you skip this loop and stay on Cowley's. Once you reach the Bench Road, stay on it and head north.

At 0.2 miles on Bench Road, fork to the right uphill on the (smaller) upper Bench Road, which will become the BST. Around mile 0.4, it will narrow so it seems less like road and more like trail. At mile 0.5, veer right on the BST as you leave the old upper Bench Road.

Pleasant Grove Bench Road via Grove Creek TH

In Pleasant Grove, drive uphill on 500 North until it becomes Grove Creek Drive. Follow it up to the paved Grove Creek trail parking area. On your bike, coast downhill to the steel gate just below the paved Grove Creek parking lot.

On the north side of the street, find the Canal Road (aka Bench Road) north. Now pedal a mile north until the Bench Road splits. Take the right (uphill) fork, which will narrow to trail after 1/4 mile. In another 0.2 miles, the BST forks away on your right, then the Sneaky Shiz trail forks to the right after another 0.4 miles on the BST.

From the Bench Road in Cedar Hills

When riding south on the Cedar Hills Bench Road, the BST forks uphill on your left. (No trail markings as of April 2022.) This occurs while you're still riding past homes, 0.2 miles from the northern end of the Valley Vista Molly's Trail. (There's a second alternate about half-way between.) If you reach Valley Vista, you missed the BST.

After 0.5 miles climbing the BST, Sneaky Shiz forks left uphill. If you don't know the area, you may need a navigation app to find your way. The trail forks are not marked!
Sneaky Shiz Trail
Most riders use Sneaky Shiz as a climbing route. Combined with a climb up through Valley Vista, it's probably the most pleasant way to reach the fabulous views on Mahogany Mountain. The overall climbing on Sneaky Shiz is around 700 vertical feet.

The trail surface is non-technical. But the many turns tend to be a bit steep and loose, so I recommend this ride for intermediates or better.

The terrain is mostly grass with bits of sage and scattered groves of scrub oak. There are no rock outcrops or tech challenges on Sneaky Shiz. The area is very sun-exposed and will be hot on summer afternoons.

Sneaky Shiz is a narrow hand-dug bench-cut, rather than being simply a co-opted game trail. But there are no turning banks to hold your tires on the downhill, so you'll find yourself checking your speed to roll around. On the way down, particularly as you near the bottom, you'll notice a few older paths heading more steeply downhill. Do Not ride these.

If your target is the viewpoint at the top of Thunderdome (a popular target for this ride), your ride will require 1700 vertical feet of overall climbing. The shortest route would use The Pit and Hard Rock of Valley Vista to the Bench Road for the connection to Sneaky Shiz, and would be a bit under 10 miles for the out-and-back. See the Valley Vista and Mahogany Mountain pages for climbing options.

The trail is smooth with occasional humps where old flood channels or 4x4 digger trails cross.
If you're using Sneaky Shiz as a climbing route, I recommend conserving your energy on the lower turns. While most sections of the trail are easy cruising, there are a lot of turns on the trail, and those turns are often long and steep. If you put too much leg into powering around those turns, you won't have much left when you hit the steeper slopes of Thunderdome.
At the top of Sneaky Shiz, you'll hit a flat viewpoint area and a T intersection with Mahogany Mountain. A left turn takes you to the Mahogany Mountain downhill route and later the (unrideable) steep slope up to the viewpoint. If the upper viewpoint is your goal, turn RIGHT (away from the viewpoint) on Mahogany Mountain, then turn left onto Thunderdome just 75 yards later.

The most common descending route is Rojo and the Rojo Connector down to the BST. If that's your goal, turn right on Mahogany Mountain and find the trail fork on your right after 0.2 miles.

We're on Mahogany Mountain southbound. The trail on the left is Thunderdome. Thunderdome starts out southbound, but will soon turn back to the north and begin climbing.
Thunderdome is 0.9 miles long, with 450 vertical feet of climbing. It extends from the Mahogany Mountain trail (just 75 yards south of where Sneaky Shiz ends) to the viewpoint at 6250 feet elevation.
While the trail does have some smooth sections, it's more narrow, more steep, and more technical than Sneaky Shiz. The gambel oak sections are tighter and are more likely to scratch if you bobble. Some embedded limestone boulders require dodging and pedal cautions.

While the main trail from Mahogany Mountain to the viewpoint goes almost straight up the slope, Thunderdome approaches the viewpoint through a series of traverses to slow the rate of climb.
Once you hit the ridgeline at the top, stop and take in the views. From here, the trail simply heads 50 yards toward the mountain and joins up with the main trail. (This trail continues uphill, should you have the leg to go further.)

So is it worth the extra climbing to add Thunderdome to your ride on Sneaky Shiz?

I think so. Yes, Thunderdome will seem tougher than all the other climbing you'll do on this ride combined, but the views at the top are extraordinary. And a little challenge to your legs and your bike-handling will do you good.

Popular loop return route:  Rojo Rolling and Mahogany Bench Connector to BST

Most riders are riding a clockwise loop. After climbing Sneaky Shiz the pedal 0.1 miles south and drop onto Rojo Rolling. This trail dumps onto the Mahogany Bench Connector. At mile 0.7, the trail hits the Bonneville Shoreline Trail, where you can connect north or south.
Most riders who climbed Sneaky Shiz will opt for the northbound return. It drops you onto the Bench Road around 1/4 mile from the top of Hard Rock in the Valley Vista trail system.

Here's the trail fork where Mahogany Mountain turns to descend. The main trail here is the steeper route to the viewpoint (and to points higher on the hill).
If you're in a hurry to get back to the valley, you can take the steep main trail down to Mahogany Mountain. It's very steep and loose for about 0.2 miles. At 0.4 miles after leaving the viewpoint on the ridge, the Mahogany Mountain downhill section will start on your right. It's marked by a rockpile.
Note that you can also choose to descend Mahogany Mountain if you return via Thunderdome. Just backtrack onto the main Mahogany Mountain trail, but ride past the entry to Sneaky Shiz. After 0.3 miles, the downhill trail will fork away on your left.

Heading downhill to the northwest. You can see that the trail continues straight.
Compared to Sneaky Sniz, downhill Mahogany Mountain is fairly straight and significantly steeper. It's often a little trenched, but it's not horrible. All-out chunder descenders may enjoy this way down. I'd only do it again if a thunderstorm were chasing me. After only 0.9 miles the singletrack dumps onto a gravel road, where you can work your way down to the Bench Road in Cedar Hills.
Bottom Line!

One of the better climbs in the Utah County foothills. Great views but not for beginners or the out-of-shape rider.

See the Valley Vista trail pages for details on navigating those trails.
See the Mahogany Mountain trail page for trails east of Sneaky Shiz.
