Cerro San Luis (Madonna Mountain)
The 'M' mountain rising over downtown SLO — a volcanic morro with a switchbacking trail to summit views and the iconic hillside letter.
🌟 Why Locals Love It
It's the after-work hike with the big payoff — a quick climb up the 'M' mountain to sunset views over all of San Luis Obispo.
What to Expect
A switchbacking climb through grassland and oak to a volcanic summit, with options from a gentle loop to a steeper summit push.
💡 Good to Know Before You Go
Trailhead access from the Madonna Inn area and Marsh Street. Exposed and grassy — bring water and sun protection. Watch for ticks in tall grass.
📍 Local Tip
Hike up for sunset and watch the city lights begin to glow below from the summit.
Best Time to Visit
Late afternoon for sunset; spring for green hills.
