Basalt and Breath: Half-Day Climbing in Baños’ San Martín Canyon
Four hours on clean basalt below Tungurahua: learn to climb where the volcano shaped the rock.
You step out of the van and the canyon takes a breath for you. The river below gurgles like a conversation between stones. Above, vertical faces of black basalt rise in columns and ledges, the raw handiwork of Tungurahua’s ancient eruptions. In ten minutes from central Baños you can stand at the lip of that canyon—the San Martín—where volcanic rock confronts gravity and asks you to test your balance, strength, and calm.
Trail Wisdom
Send Shoe Size Ahead
Guides ask for shoe sizes before the trip so rental climbing shoes are ready and comfortable.
Hydrate Before You Climb
Bring a full 1-liter bottle; the canyon can be warm and you’ll appreciate sipping between routes.
Use Reef-Safe Sunscreen
Sun reflects off basalt and the river—apply sunscreen and reapply after sweat.
Listen to the Safety Brief
Most risks are preventable—pay attention to belay cues and guide instructions.

Baños developed around thermal springs and pilgrimage and later diversified as an adventure tourism hub beneath Tungurahua.
Seasonal Guide
spring
Best for: Fewer Tourists, Cooler Mornings
Challenges: Intermittent Rain, Muddy Approaches
Spring brings green canyon walls and fewer crowds, but expect occasional showers that can make approaches slippery.
summer
Best for: Dry Rock, Longer Days
Challenges: More Tourists, Afternoon Heat
The dry season (June–September) is prime: routes are drier and more reliable, though afternoons can be warm.
fall
Best for: Clear Light, Quiet Crags
Challenges: Unpredictable Weather, Shorter Days
Autumn-like months deliver crisp light and quieter sectors, but check forecasts for sudden rains.
winter
Best for: Off-Season Rates, Cool Conditions
Challenges: Cloud Cover, Possible Eruptive Activity Advisories
Winter months are cooler and less busy; always verify volcanic activity updates and your guide’s safety plan.
