Trails
Castle Peak And Conundrum Peak Loop (2WD Trailhead) – 12.3 Mile Loop – 5,357 Feet Elevation Gain
If you have a 4WD vehicle with high clearance, you will be able to make it passed this trailhead. 4WD vehicles can make it passed this first point during good conditions, but may have to stop at one of the early on tent sites. Regardless of the vehicle, be prepared to make this hike from the 2WD trailhead in case of conditions that make the road impassible.
From this trailhead, hikers simply hike along the road. Eventually, hikers will reach the 4WD trailhead at 11,150 feet. Continue reading the rest of the route from the 4WD trailhead.
Castle Peak And Conundrum Peak Loop (4WD Trailhead) – 6.7 Mile Loop – 3,757 Feet Elevation Gain
This route saves 5.6 miles round trip and and about 1,600 feet of elevation gain.
We recommend summiting Castle Peak first, then descending the ridge to the saddle between both peaks, and then summiting Conundrum before returning.
Once reaching the 4WD trailhead, hikers can continue along the road, bearing right at the first junction. The road is easy hiking, and the trail continues to switchback and follow the road all the way to Montezuma Mine and the parking area at 12,650 feet.
Hikers begin ascending boulders and loose rock. .3 miles from the mine parking area the trail breaks off to the right towards Conundrum peak, but hikers should stay left towards Castle Peak. .3 miles after this, hikers will see cairns heading up to the left via switchbacks to the ridge.
Hikers take these switchbacks and follow the ridge to the summit of Castle Peak. This remains class 2, however the ridge does have some exposure points with steep drop offs. The views are simply incredible.
From here, hikers follow the ridge down to the saddle between Castle and Conundrum.
The section of this hike still remains class 2, but the trail from the saddle back down to Montezuma Mine can be tricky during snowy times or muddy times. During those times, it may make sense to head back up to the summit of Castle and descending the same route.
It is a relatively steep decline to the saddle, and incline back up to the summit of Conundrum. The views are incredible.
Castle Peak & Conundrum Parking At Montezuma Mine – 2.4 Mile Loop
This is a common road for high clearance 4WD vehicles capable of handling some pretty tough roads. If you have a vehicle that can handle this, you can cut off a large portion of this hike.

Hiking Castle Peak In Winter
As with any 14er, this hike is significantly more dangerous in winter. These summits are doable in winter months via the same route, but added caution is needed. Hikers will very likely have to begin at the 2WD trailhead for winter summits.
