Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.
Colorado 13er · Northeast Ridge from Gibbs Peak
Overview
Mount Marcy is a remote summit on the main crest south of Gibbs Peak. The usual plan is a long day from a South Brush Creek camp over De Anza Peak and Gibbs Peak.
From Gibbs, return to the main crest and head south, over or around Point 13,335, then southwest to the top. The 1.5-mile walk is tundra and embedded rock, Class 2, with one rockier spot. Marcy can also be linked north from Silver Peak and the Lakes of the Clouds.
Counting De Anza and Gibbs, the round trip from the Gibson Creek trailhead is about 28 miles with 8,000 feet of gain. Mileage and gain are our estimates. Most people backpack in and camp near treeline, then climb the next day. The Ducket Creek trailhead to the north is a bit shorter, with about 1,000 feet less wasted climbing on the Rainbow Trail.

Crux
The long approach. The peaks themselves are easy.
Route-finding
Easy once you're on the crest. The Rainbow Trail has many junctions; stay on it north to South Brush Creek.
From Westcliffe, drive south on Colorado 69 and turn west on County Road 160, across from the gas station. After 6 miles, turn right on County Road 164, go 1.5 miles, then left on County Road 172. The Forest Service boundary (often the winter closure) is 0.3 mile up, and the trailhead 0.2 mile beyond.
Much of the land along the way is private. Park only at the trailhead, or along the road with care if it is full, and don't camp on the drive in.

The line is elevation, the band underneath is the ground, and the numbered dots match the steps below. Mileage and elevations are approximate.
1
Gibson Creek trailhead 9,130' · 0 mi
Take the side trail north-northwest past private land to the Rainbow Trail and turn right (north).
2
Rainbow Trail 9,300' · 0.4 mi
The Rainbow Trail crosses drainage after drainage. Expect about 2,000 feet of extra up and down before the next turn.
3
South Brush Creek Trail 9,200' · 6.2 mi
Turn left (west) at the signed junction with a register.
4
Goat Creek 9,500' · 6.8 mi
Cross the creek, usually a trickle, then climb more steeply about half a mile to a ridge.
5
South Brush Creek 9,900' · 7.6 mi
Drop to South Brush Creek and find a place to cross; it can be high in early summer. The trail then stays on the north side, well above the creek.
6
Treeline camp 11,650' · 9.75 mi
The middle stretch is the steepest. Near the last trees, around 11,600 to 11,700 feet, look for a sheltered campsite a little north of the creek.
7
Cross the creek 11,700' · 9.9 mi
Find a way across South Brush Creek near camp.
8
De Anza Peak 13,391' · 11.25 mi
Climb De Anza's north flank to the northeast ridge and the top.
9
Gibbs Peak 13,577' · 12.75 mi
Follow the ridge about 1.5 miles to Gibbs on tundra and embedded rock. Stay on the west side of the crest; the east side drops steeply into Horseshoe Bend. You lose over 600 feet and climb about 800. Scramble some blocky rock at the top.
10
Point 13,335 13,335' · 13.6 mi
Walk back southwest to the main crest and turn south. Go over the point or skirt it; this is the rockiest bit.
11
Summit 13,504' · 14.25 mi
Continue southwest on tundra to the top.
Getting down
Walk the ridge back north toward Gibbs. Walk back southwest along the ridge, then northwest to the Gibbs-De Anza saddle. From a little east of the saddle, descend a broken ramp of tundra and rock, crossing three gullies, then drop into the Horseshoe Bend drainage. Contour on the west side of the creek toward the trees near Point 11,575, where game trails lead back to South Brush Creek and camp.
If things go wrong
The Gibbs-De Anza saddle and Horseshoe Bend lead back to camp.
3D flyover
No 3D flyover for this peak
Above the South Brush Creek Trail the route is trailless ridge walking. A flyover only works when there is a set trail to trace. Without one, the line would be a guess, and a guess could send you the wrong way on the mountain. Use the step-by-step route with a good map and GPS track instead.

We haven’t found a good video of this route that matches the way we describe it. The route strip, junctions and 3D flyover show the way in the meantime.
This describes the route on a dry summer day. Most 13ers see few people, so there may be no one along behind you. Check recent conditions the week you go, carry a map, tell someone your plan, and turn around when the day tells you to.
