Hiking Pacific Peak: Free 13er Guide and Map

Pacific Peak is a stunning mountain in the Tenmile Range of Colorado. Easily viewed from Vail Pass and nearby ski areas, hiking Pacific Peak is a moderately challenging scramble that includes a steep headwall as its crux. In early summer months this route still holds plenty of snow, so bring along an ice axe and microspikes/crampons if you plan to do it in June or early July. For beginners I would advise waiting until August for hiking Pacific Peak. Start planning your ascent below with my complete route guide.

Hiking Pacific Peak - Southeast Slopes Route

NOTE: You must now take the shuttle or reserve a parking permit in advance to visit McCullough Gulch. Click here to learn more.

Park at the gate and start hiking Pacific Peak along the road up McCullough Gulch. Parking here along the road fills quickly, so it’s a good idea to arrive early to ensure you find a spot. After around half a mile, take a trail to the left of the road and head into the forest. 

Near 11,600 feet there are several waterfalls. You can take a social trail to view the falls or stick to the main path on the right to climb over this moraine. You’ll come to a beautiful alpine lake, with many dispersed camping sites around it. It’s a great place to pause for a snack while hiking Pacific Peak

Head along the north side of the lake along the trail, and look for a ramp along the stone moraine ahead of you. Follow cairns and trail segments that take you up into the upper Basin. There may be snow here in early summer, use microspikes while hiking Pacific Peak from here out if needed.

The trail here will begin to fade as you near another lake around 12,500 feet. Angle northwest and climb a rib that separates you from the northern half of the basin.

From here, you have a half-mile talus hop to reach the bottom of the headwall, which is the crux of the route You’ll climb this to reach the saddle that lies between Atlantic and Pacific Peak. The headwall holds snow late into the year. It’s a good idea to bring an ice ax and crampons in case you come across snow. Take your time climbing this headwall, sticking to the center for the last steep climb.

As you near the top, angle towards the left and continue up to the ridge. Towards your left is Atlantic Peak, and to the right is Pacific Peak, though it may be hidden behind a false summit. Take a moment to check the weather before you climb this final few hundred feet.

Hike north up the ridge and bypass the small point at 13,500 feet. Continue up the south ridge to finish hiking Pacific Peak and reach the summit. From here you can see into the Sawatch range to the west or the Front Range to the east. Make sure you begin your descent quick enough to reach the tree line before afternoon thunderstorms become a hazard.

Pacific Peak, like its neighbor Atlantic Peak, is named after the continental divide that runs nearby. Strangely enough, both peaks are on the Pacific side of the divide, so Pacific Peak is the correctly named of the two.
