About Cannon Cliff

Cannon Cliff is New England's biggest and most serious multi-pitch trad venue — a 1,000-foot east-facing Conway/Kinsman Granite wall in Franconia Notch State Park, notorious for rockfall. The Old Man of the Mountain fell off in 2003 and pieces of the wall still come down each spring; Mountain Project's area page explicitly warns "the cliff faces east and many a climber has been caught unaware by fast-moving storms coming from the west." Mountain Project's top-ranked classics are Lakeview (5.6), Whitney-Gilman Ridge (5.7), Moby Grape (5.8), Vertigo (5.9), and VMC Direct Direct (5.10+). East aspect and elevation mean cold spring conditions and comfortable midsummer temperatures on the wall — July and August are the practical season with occasional dry September windows. Approach 20 minutes from the Cannon Cliff pull-off, which is accessible ONLY from southbound I-93 (northbound drivers must exit at Tramway and reverse). Free day-use access; small silver rockfall-monitoring sensors on the cliff should not be disturbed. Helmets essential. No active peregrine ban listed for 2026, but historic peregrine activity means it's worth a quick NH F&G check in spring.
