Lambert Park, south end trails

The southern end of Lambert Park lies on a dry hillside consisting mostly of sage brush. There are occasional stands of oak brush -- some of it skeletons from three fires in the last 6 years. This area tends to dry quickly after storms. In the spring, the trails are dry a week or two after the west-side trails (such as Middle) are ready to ride, but a few weeks before the north trails dry.

On the lower slopes of Lambert's south end, the north-south bike trails are crossed by the broad Lambert hiking-only loop trail. The intersections are open with good sight lines, but remember to yield to hikers.

Climbing uphill on the Zag trail.

The theme of the south end is "climb up, fly down." The favorite climbing routes seem to be (1) Ziggy uphill to the top of Zag, then over to Brown Dog, and (2) Zag plus White Dog. You can climb Black Dog or Wildcat, but there are a couple of tough spots.

The Corkscrew trail traverses the top of the park property north-to-south before descending on private property to city streets. It ties the tops of (from north to south) Ziggy, White Dog, Brown Dog, Black Dog, and Wildcat together.

Rocking the curves in a ravine on the Ziggy trail.

There's a mid-level traversing route consisting of the top traverse of Zag, Indian, and Flank. This is for those who want to climb only on the more-mellow lower slope.

After climbing as high as you want to go, it's time to pick a descending trail. Make your traverse over to the downhill. Wildcat and Ziggy are used almost entirely as downhills because they're straighter and therefore have a steeper slope.

Turning from Ziggy onto the bottom of White Dog. To get to this spot, you could either climb Zag or Ziggy.

These trails are rarely used in the winter because of lack of bike traffic to pack the snow, and sun exposure that creates muddy spots. See the general information page for Lambert Park.

The trail listing below will first discuss routes that are considered climbs and descents (such as White Dog and Zag) which have an east-west general direction, then the traversing trails going north-south (such as Corkscrew and Flank).

In 2018, there's a re-vegetation project affecting the upper Zag and Brown Dog area. The area was burned twice in recent years. Sage brush is better than acres of cheat grass.

Riders who want to start at the south end can choose from two evolving trailheads -- by which I mean they're affected by construction on nearby private land. One is the popular High Bench ("church") trailhead. The other is the end of Bald Mountain Drive. You can also pedal into the park via the Redford Run trail. See below -- and the main Lambert Park page -- for additional information.

Bruce cruises between groves of oak brush at Lambert's south end. This area tends to get toasty warm on summer afternoons.

East-West Routes (climbing and descending)
(listed north to south)
Ziggy Trail
 Length: 0.5 mi. 
 Elevation change: 200 ft
 Tech: intermediate
 Usually a descender but can be climbed
 Upper end top of White Dog, N end of Corkscrew N40 28.070 W111 44.999
     Straight at White Dog and Zag m 0.2 N40 28.109 W111 45.144

     Straight at Zag fork m 0.5 N40 28.000 W111 45.372
 Bottom end on south Middle N40 27.973 W111 45.358

About half-way down Ziggy, with Lone Peak in the background.

Ziggy is usually used as a descending trail. Its orientation is east-west. Local riders will climb Corkscrew from the south then descend to the middle of the trail system via Ziggy. The top of Ziggy begins as a continuation of the northbound Corkscrew. Straight for Ziggy, left downhill for White Dog.

Lower Ziggy follows an old wash, offering a swooping ride with sidewall hits.

On its way down, Ziggy hits the bottom of White Dog then the top of Zag. It passes the ZPC (Ziggy to Poppy Connector) as it drops into a shallow ravine. Here you get the whoops and swoops and you head down to join Zag. The trail ends on Middle at the water tank road.

Swooping through sagebrush on Ziggy.

You can climb Ziggy, it's just a stiffer climb than the alternatives. Most climbers use only a piece of the trail. I often take Luge to Poppy, ZPC to Ziggy, then climb Ziggy to White Dog and on up to Corkscrew.

Almost down to the Zag trail fork.

Zag Trail
 Length: 1.0 mi.

Rolling into a turn around a big stand of squawbush.

Zag is the ultimate "cover a lot of space going nowhere" trail. It zags back and forth across the slope, putting in a mile of riding while actually going only 0.2 miles away. But you came here to ride, right? It's a gentle climb, or descent, with frequent reversals of grade that almost double the total climbing.

Climbing Zag. The back-and-forth through sage flats gives you plenty of chance to see the great views from Lambert Park.

The top of Zag begins on the north side of the southern riding block, right next to the subdivision border. It traverses the hill southbound to Indian -- which then extends to Flank, forming a mid-level traversing trail north to south-- before winding back and forth down the hill.

Most of the riding on Zag is straightforward. Nothing techy. Gentle climbing is mixed with areas of coasting.

As a climbing route, Zag begins on the Middle Trail near the water tank road. It can be your connection to the upper-level trails White Dog, Brown Dog, and upper Ziggy. These trails connect up to the higher-level traversing trail Corkscrew.

Handlebar view as we approach the Zag forks to the right, away from the combined Zag/Ziggy.

Zag spends most of its time on a sagebrush slope. This area used to be an orchard, and a couple of almost-dead wild apple trees remain. The top of Zag was burned down to dirt by a fire (then washed over by a massive floow) a few years ago, and the vegetation is still recovering. So the top couple of meanders pass through meadow.

Looks pretty, but most of it is cheat grass, which will dry out in a few weeks.

White Dog
 Length: 0.4 mi. 
 Elevation change: 100 ft
 Tech: intermediate
 Twisting route, climb from Zag or descend from Corkscrew
 Bottom end Ziggy just uphill from top of Zag N40 28.109 W111 45.144
 Upper end N end of Corkscrew, top of Ziggy N40 28.068 W111 45.001

Almost to the top. Bruce pedals past a large dead oak as he approaches the last turn before hitting Corkscrew.

White Dog is a twisting trail oriented east-west. It's lower end begins a few feet uphill from the end of Zag on Ziggy. The trail then winds back and forth up the mountain until it hits Corkscrew near the wilderness border. At the top end, a left turn takes you to an old doubletrack -- upper Ziggy -- for a quick descent to the bottom. Right takes you across the mountain southbound on Corkscrew.

While most riders select White Dog as a climbing route, it's also a fun descender.

Much of the terrain here is debris flow from a massive flood. Mud and rocks roared down from steep fire-burned slopes above the park, covering much of the upper hillside in the area of White Dog.

Most of White Dog was destroyed by a massive mud-and-rock flow following a fire on the hill above. The trail was rerouted, using the flood debris as "features." Then another fire came through and killed the remaining trees. So it's not much on beauty any more. But it's fun riding.

Riding past evidence of two fires, both human-caused. Tall trees killed by fire #1, and re-grown oak brush killed by the second fire.

White Dog is the most popular of the "dog trails," all of which are oriented east-west as climbing or descending routes. It's significantly more technical to ride than Brown Dog, but not as tough as upper Black Dog.

Northbound on White Dog as we approach the border of the subdivision.

Brown Dog
 Length: 0.2 mi. 
 Elevation change: 100 ft
 Tech: easy-intermediate
 Climb or descend, slow turns
 Upper end on Corkscrew N40 28.002 W111 45.027
 Bottom end on Zag N40 28.037 W111 45.147

The fork of Brown Dog off of Corkscrew.

Brown Dog connects Zag (near the Indian trail fork) to Corkscrew. It curves through a few turns, wasting little time. As a climber, it's smooth but more aerobically taxing.

As a descending route, it's fast. And relatively non-interesting.

This area of the hill was mostly meadow even before the latest fire came through and took the gambel oak. So there's a revegetation effort going on in 2018 to plant shrubs and trees on this slope..

The little plants here are sage brush, planted in 2018 to try to get something -- other than cheat grass -- to cover the hillside.

Black Dog
 Length: 0.5 mi. 
 Elevation change: 200 ft
 Tech: upper-intermediate
 Usually a descender, can be climbed
 Upper end on Corkscrew N40 27.961 W111 45.017
     Cross Indian m 0.3 N40 27.953 W111 45.190
     Cross Flank m 0.5 N40 27.918 W111 45.262
 Bottom end on Middle near High Bench N40 27.936 W111 45.324

Almost to the bottom of Black Dog as we rocket downhill.

Black Dog is one of the lesser-beloved trails here, because it has some nasty spots on the top end that are tough for intermediate riders to handle, either uphill or down. So the track is narrower. And sometimes the grass tries to grow between the rocks of the trail.

Handlebar view of the trail. Note that it's mostly rock, and plants are trying to grow between those rocks.

The trail is oriented east-west, and provides one of the more direct climbing routes from the High Bench area up to Corkscrew. As a climber, it's quite nice until you hit the top two turns -- steep quick meanders in a gully that require a bit of grunt and skill to ride clean.

The upper end is on Corkscrew, where a right turns takes you downhill (or to Wildcat) and a left turn takes you northbound on the traverse across teh top border toward Brown Dog, White Dog, and Ziggy.

On the lower half of Black Dog, with Lone Peak providing a dramatic backdrop.

As a descending route, Black Dog is a bit bumpy due to embedded rock in its upper half. But it's a quick and fun drop.

Black Dog has a few areas that lost oak trees due to the fires. But most of the trail escaped damage, so it has some scrub oak groves alternating with sagebrush.

Racing down Black Dog. Note the burned oak brush that's had a few years of re-growth.

View from the top of Wildcat as it forks off Corkscrew.

Much of Wildcat lies just inside the official southern border of the Alpine City park. In the past, Wildcat was known for user-constructed jumps and stunts. Most of these have been removed, or have eroded away.

The trail runs east-west and is almost entirely used as a descending route. With relatively little meandering, it's one of the most direct descents.

Narrow singletrack provides a fast route downhill.

Wildcat forks off of Corkscrew just south of a dirt road that marks the edge of the park. It extends down to the High Bench gravel Road just southeast of the High Bench trailhead.

Southbound on Corkscrew just south of White Dog.

Corkscrew is primarily used as a traversing trail to connect a climbing route with a descending trail. It runs across the top of the city property, just below the US Forest wilderness. On this traversing section are (north to south) Ziggy and White Dog, Brown Dog, Black Dog, then Wildcat.

Descending Corkscrew.

On the southern half, Corkscrew is a climbing or descending route for local residents who ride their bikes to Lambert Park. The entry to Corkscrew is on your right as you pedal northbound on the Redford Run trail -- about 50 yards before Redford Run hits Bald Mountain Drive.

There's a wide area for parking at the end of Bald Mountain Drive in Alpine for those who want to park at the far southern end. Straight and a bit left is doubletrack leading to High Bench. Backtrack about 50 yards to find singletrack on the east side, which will take you to the bottom of Corkscrew.

Passing the top of Brown Dog.

Corkscrew can be a grunt climb. But it's a popular route to climb into the park's trails. Shortly after Corkscrew begins, the Flank trail forks left, offering a mellower entry to the trail system.

 North end water tank road just uphill from Middle N40 27.961 W111 45.326

Looking south from the northern end of Flank on the water tank road.

Flank is a north-south traversing trail. It extends from the water tank road just uphill from Middle onto private land south of the city park. It ends on Corkscrew. It can be used for a loop ride with Corkscrew and your choice of another trail for climb/descent.

Most of flank is open sagebrush. There's an occasional tree or two.

From the east slopes of Alpine's homes, you'll reach Flank by riding Redford Run north along the High Bench irrigation canal. Before reaching the southern temporary trailhead, fork to the right uphill on Corkscrew. There are a couple of cheater connectors to Flank. The official trail is the furthest uphill, marked by a trail sign.

 Bottom end on Flank N40 27.823 W111 45.183

Looking south on Indian. When southbound, you'll spend a bit of time among the trees, then traverse open sagebrush with plenty of views.

Indian is a short traversing trail located mid-mountain. It is oriented north-south. It connects the top turn of Zag (near the bottom of Brown Dog) to Flank with a steady rate of descent..

Indian can also function as a climbing route to the top of Zag (and the bottom of Brown Dog and White Dog, or the middle of Ziggy). Riders coming from the south end can take Flank to Indian, then climb on up to upper Zag.

The top of Indian (straight ahead) forks off the upper turn of Zag. The net tubes are protecting brush planted in 2018 to mitigate fire damage.

Getting there: Take I-15 to the Alpine/Highland exit, just south of Point-of-the-Mountain. Drive straight east 5 miles towards the mountains, turning left at the stoplight in Highland (where you see the grocery store and gas station). Drive 2 miles north into Alpine to the 4-way stop at 200 North. Turn right. At the next stop sign, turn left. You'll be on 200 East, which becomes Grove Drive. Continue northeast on Grove for two miles. The road will turn 90 degrees to the right. Pass two streets on your left, then arrive at a T in the road. Turn right, across the river. At the fork in the road, go right for the Bowery parking area, left for the Rodeo grounds.

Rodeo grounds trailhead: Keep left at the fork and drive 0.25 mile on pavement, then turn right onto a dirt road and drive 0.25 mile. The trailhead is on the right side of the road, where you'll see a parking strip and a bathroom just before the rodeo arena. (Toilet.)

Bowery trailhead: Keep right at the fork as you cross the river on the paved road. Pass the High Bench dirt road on your right. About 300 feet further up the paved road, keep straight as the main road turns right, entering a smaller road. 500 feet up the dirt road,, the Bowery pavilion is on the left, with a parking lot on the right. (Toilet, pavilion, water.)

High Bench ("church") trailhead: About 1.5 miles up Grove Drive (as above), turn right on Alpine Boulevard. Go 1/2 mile until the road turns from east to south in front of a big church. After you pass the church, fork left toward the mountains. Immediately after the church's back fence turn left onto a narrow paved road and proceed to the trailhead. (Toilet, shaded picnic, water.)

Moyle Drive:  On Alpine Blvd, turn left onto Moyle and drive to the end.

Bald Mountain Drive:  Turn onto 100 South in Alpine. Drive east until you're forced to turn at Country Manor Lane. Go left. At 300 North, turn right, then take the next left on Bald Mountain Drive. Go to the end of the road and park.
