Overview: This trail segment spans from Canyon Lake TH to the Dutchman Trail #104. Which is the Boulder Basin where Boulder Creek forks into East, Little & West Boulder Creeks.

This trail is somewhat misnamed. The first half-mile from the Canyon Lake Trailhead allows views of Boulder Canyon, however it quickly turns away to a climb up Frog Peak. Descending from the peak, you actually approach and cross La Barge Canyon before finally getting into Boulder Canyon, which you follow for the remainder of the trail. Day hikers rarely make it to Boulder Canyon.

Hike: Starting from Canyon Lake Marina, park at the designated spots for hikers and cross Apache Trail. The trail in this section allows views of the inlet created where Canyon Lake flooded the original lower reaches of boulder canyon. The trail climbs to a hill, providing some glimpses of the lake inlet and interesting mesas to the west. From the hill, the trail proceeds east, climbing for Frog Peak. (This hill is the departure point for "La Barge Lowest Loop"). After a steady climb to the peak, you will be given an incredible view across Canyon lake and be able to see as far as the interesting alcove with the waterfall north of Tortilla Flats, admire the enormous cairn created on this peak. I do not know the history of this monstrous cairn; so if someone has some information on this, please send me a PM.

From here, you descend on the somewhat rocky trail on the way down to La Barge Creek. Suggested side trips for this area are: "La Barge Canyon View". You have an excellent view of the stern of Battleship Mountain as you descend.

After reaching the creek bed, the trail crosses to the west side and begin a minor ascent over the saddle. (The crossing is the departure point for "La Barge Lower-Box Loop")

At the saddle between La Barge Canyon and Boulder Canyon on the trail, you will come upon the Indian Paint Mine. The pit that they extracted red clay to make their paints and pottery is still apparent, and the nearby "furnace" area is still discernible.

Descending into Boulder Canyon proper, the trail crosses Boulder Creek to reach the west side of the trail. Shortly you will run into the first intersection with Second Water Trail. Continue on south on the Boulder Canyon Trail. From here, the trail gets a bit more rugged and less defined as it follows along Battleship Mountain. It tends to stay close to the sides of the creek, but makes frequent crossings. Cairns should lead you in the right direction, but the area is somewhat over-cairned in areas leading to some confusion. It is generally rocky and the creek bed contains some catclaw, shrub live oak, and other vegetation.

The canyon is fairly narrow, but the slope of the climb is gradual. Next you'll reach the intersection with the Cavalry Trail #239. The intersection is signed, however if you are not on the east side of the creek at this point, you may miss it. Continue south on the Boulder Canyon Trail.

Before the end you will see Needle Canyon entering from the east, which looks mighty formidable. Finally, the trail winds its way to flatter ground on the west side and closely watching for cairns will lead you to the official intersection with the Dutchman, which is also very close to the Bull Pass Trail #129 and somewhat near Black Mesa Trail #241. These intersections are well signed, however the hiker should be warned that this final intersection is fairly indistinct and one should pay careful attention to find where the trail finally leaves the creek. I would consider it likely some will miss the trail and pop out on either the Bull Pass or simply somewhere along the Dutchman, which may lead to some confusion. I have given directions to two groups of very confused folks I've found standing at this intersection, some with GPS, and I believe this is the cause of the most confusion.

The views of Weaver's Needle at the end are motivation to go all the way to the end of the Boulder Canyon, but turn around as your fitness level and time before darkness dictate if doing a dayhike.

There is a small restaurant at the Marina, which a hungry hiker may find to their advantage.

Boulder Creek is seasonal. Caution should be exercised crossing either La Barge or Boulder Creeks if it has rained recently. During a storm flash floods are a real possibility at these crossings due to the tremendous area these creeks are responsible for draining. 3-5 feet of flowing water can take down a grown man. If intending to camp, it would be best to obtain a water report for Boulder Creek as it is typically dry in the summer.
