Albuquerque Trails

Santa Fe, NM: Horseshoe Lake

Follow a primitive trail--and keep an eye out for alpine-loving marmots and big horn--on this 11.5-mile overnight to Horseshoe Lake in the Carson National Forest's Pecos Wilderness.

Perfect for hikers craving a sweet, secluded spot in the Pecos, this 11.5-mile overnight begins with a gradual forested climb on the well-established Serpent Lake Trail #19 and crosses into the wilderness near mile 3 (where the climbing also mellows). This route bypasses the 0.25-mile trail to Serpent Lake and instead branches south on a faint path just before the main trail begins climbing toward Jicarita Peak.
Be sure to bring your navigational tools—a topo map, compass and GPS—as the second half of this hike isn’t on area maps and requires some route-finding skills to stay on track. The trail is in relatively good shape as it skirts treeline headng south and climbs a ridgeline toward the hike’s high point at mile 4.7. It’s a gradual downhill from there to the shores of Horseshoe Lake where you’re likely to be the only campers at little-used and pristine sites on the lake’s south side.
Note: Help to preserve the lake basin by following LNT principles: packing out all trash and paper, camping well away from the shoreline, and using existing sites and fire rings, or refraining from fires completely.

Trail Facts

  • Distance: 18.5



Location: 36.057738, -105.500786

Park in the small lot at the Alamitos Trailhead. Leave room for others (including horses trailers) to access the trail and bring water (none is available at the trailhead).


Location: 36.058137, -105.505314

From the trailhead, you’ll cross a stream and follow a wide path. Join the narrower Trail #493 here and begin climbing through the forest.


Location: 36.057232, -105.512422

Dip down to cross a small ditch. This landmark at mile 0.75 ensures you’re on the right path.


Location: 36.045837, -105.533874

The trail turns south near mile 1.5 and climbs steeply for another 1.5 miles to the Carson National Forest Wilderness boundary where the climbing mellows.


Location: 36.043226, -105.540156

To continue toward Horseshoe Lake, you’ll bypass this right-hand turn toward Serpent Lake and follow a faint trail leading left in about 150 feet. If you’d like to add a half-mile to your trip, consider a quick round-trip detour to Serpent Lake for a lunchtime picnic.


Location: 36.042117, -105.540875

If you started gaining elevation on Trail #19, you may have gone too far and missed the left-hand turn toward Horseshoe Lake. This waypoint is just over 100 yards south of Trail #19 on the Horseshoe Lake Trail.


Location: 36.040467, -105.541283

The 2.4-mile stretch between Trail #19 and the lake heads south below a ridgeline to the west. The trail is little-used and unmaintained, so it can be difficult to follow. Head generally south and cross-reference map features and waypoints often.


Location: 36.038017, -105.541298

Hovering around 11,800 feet as it follows the ridge contour, the trail skirts treeline. Continue south near the line of vegetation and follow the ridgeline around toward the open hillside which you’ll begin climbing in about 0.3 mile.


Location: 36.032108, -105.535912

The trail is intuitive, but continue referencing navigational tools to make sure you’re on the right track. From this point, it’s a short climb up the rocky alpine slope to cross the ridge up ahead.


Location: 36.031197, -105.536302

Instead of cutting across the slope directly, trace a gentle switchback above this rocky area by climbing slightly west and angling eastward toward the ridge.


Location: 36.030243, -105.534218

The trail’s high point is on the ridgeline at mile 4.7 and sits just below 12,100 feet. Marvel at the mountain views to the east before turning downhill toward Horseshoe Lake.


Location: 36.028003, -105.534523

Look left for a view of a smaller lake well below the trail. Continue south for this route’s lakeside destination.


Location: 36.024652, -105.536288

If rocky ledges and outcroppings block your path to the lake, just pick your way across and above them. Up ahead, you’ll begin the gradual 200-foot descent into the lake basin.


Location: 36.020902, -105.53588

Cross this small, intermittent stream just before reaching the lakeshore.


Location: 36.019661, -105.534142

This spot at the edge of the lake is a great place to catch morning views of marmots playing on the lake’s west side.


Location: 36.018073, -105.532222

Find a campsite on the south end of the lake. Next day: Pack up camp and return to the trailhead.

Horseshoe Lake

Location: 36.020637, -105.535597

The pristine surrounds of Horseshoe Lake as seen from the trail. Do your part and follow LNT principles to help preserve the lake basin.


Location: 36.043227, -105.540075

This unmarked turn leads to Horseshoe Lake, stay to the left of the tree.

Baby Big Horn

Location: 36.030733, -105.535612

Keep an eye out for big horn sheep that frequent the area.


Location: 36.030499, -105.53484

Alpine flowers are abundant at this altitude in the springtime. Tread lightly, alpine meadows and terrain are fragile.

Small Lake

Location: 36.028009, -105.534443

This lake below the trail looks like a tempting spot to camp, but continue south. You’ll be glad you did.


Location: 36.023772, -105.536929

Fat fellows like these also frequent rocky outcroppings and the areas alongside this high-altitude trail.


Location: 36.02019, -105.537715

The talus slopes above the lake also host pika like this little guy.

Horseshoe Lake

Location: 36.020052, -105.537586

This view of the lake from the slopes above its west side show the peninsula that lend the lake its name.
