Rocky Mountain National Park: The Petit Grepon

The skyline above Sky Pond will stir the soul of most any climber. A series of massive spires, some over a thousand feet tall, call us in unison to set forth and venture toward their exposed summits. In the middle of the group is the Petit Grepon, a 1,000’ tall slender blade of granite. The South Face of “The Petit” is likely one of the most popular alpine rock climbs in the Park, if not North America. The Petit’s popularity will be evident not only when you see if for the first time, but also as we get closer to the summit and the pitches get sweeter and more exposed.

The approach, beginning early in the morning, starts from the Glacier Gorge trailhead then follows Loch Vale trail to Sky Pond, a distance of about five miles. This takes on average three hours including the time walking up the talus after Sky Pond to the base of the route.

South Face Route, 5.8 III

The South Face route follows a corner/chimney system for the first half of the climb before joining the exposed south side of the summit blade. Beginning at the base of the south face, a couple of pitches in a right facing corner gives way to a chimney before returning to a crack system for a handful of pitches were a steep, thin crack provides the technical crux of the route. Following the crux pitch, a trio of exposed pitches along the south arête of the spire lead to the summit. In case you haven’t searched “Petit Grepon” and seen images of the summit, two words: small and exposed!

From the summit, six rope length rappels comprise the descent. Arriving at our packs we’ll get sorted out and start the hike back to the car. In the daylight you’ll have the pleasure of seeing the scenery passed in the dark on the approach including Loch Vale.

A good pair of wrap around sunglasses are an essential item for all of our trips. When the sun shines brightly on fresh snow in the mountains your eyes will thank you for a quality pair of shades. Looking good is important too.

Essential for all of our programs. SPF 30 would be our minimum recommendation. Typically a 4 oz. bottle will suffice but consider trip length when deciding how much to pack.
