Summit the Silent Cone: A Day on Cerro Colorado
A manageable Patagonian summit with big views, local guides, and volcanic stories
You start before the town has finished waking—fog still clinging to the shoulders of the Andes, headlights cutting ribbons through low cloud. The van eases away from San Martín de los Andes, and the road climbs past stands of lenga and coihue, trees with trunks like old hands. By the time the guide shuts the engine and points toward the ridgeline, the volcano is waiting: a quiet, squat cone of weathered rock and wind-swept grass that owns its horizon.
Trail Wisdom
Start Early
Morning starts often avoid afternoon wind and cloud buildup on the summit; it also gives you time to return to town for dinner.
Bring Layers
Temperatures can swing quickly from cool forest shade to wind-exposed ridgeline—pack a breathable insulating layer and a wind shell.
Sturdy Footwear
Expect volcanic scree near the top—trail runners with good tread or light hiking boots help with traction.
Hydration & Snacks
Carry 2–3 liters of water and calorie-dense snacks; the ascent is sustained and calories feel worthwhile at the summit.
Local Knowledge
Hidden Gems
- •Viewpoint above Lake Lácar on the eastern flank—less frequented and great at sunrise
- •A short side trail to basalt outcrops revealing columnar structures and fossilized lava flows
Wildlife
Andean fox (zorrita), Southern Andean deer (huemul) — sightings are rare but possible
Conservation Note
Stick to marked trails to minimize erosion on volcanic soils, pack out all trash, and follow your guide’s instructions to protect fragile alpine vegetation.
Cerro Colorado is an extinct volcanic cone within the broader Andean volcanic belt; the region has been inhabited and traveled by Mapuche communities for centuries.
Seasonal Guide
spring
Best for: Wildflowers, Milder temperatures
Challenges: Unstable weather, Lingering snow at higher elevations
Spring (Sept–Nov) brings melting snows and a surge of greenery—good visibility but variable weather; bring waterproof layers.
summer
Best for: Stable weather, Long daylight hours
Challenges: Strong sun, Afternoon winds
Summer (Dec–Feb) is the most reliable for clear days and warmer temps; sun protection and early starts are recommended.
fall
Best for: Crisp air, Fewer crowds
Challenges: Cooler temps, Shortening days
Fall (Mar–May) offers sharp light and turning foliage; pack warmer layers for colder summit conditions.
winter
Best for: Snowy landscapes, Quiet trails
Challenges: Snow and ice on route, Short daylight and cold
Winter (Jun–Aug) transforms Cerro Colorado into a snow scene—only attempt with proper winter gear and local winter-guided options.
Photographer's Notes
What to Bring
Hiking boots or trail runnersEssential
Provide traction on mixed dirt and volcanic scree and protect ankles on uneven ground.
Wind shell and midlayerEssential
Layering lets you adapt quickly to the Andes’ fickle weather, especially on exposed ridges.
2–3 liters water and snacksEssential
Sustained ascent requires hydration and energy—plan for no reliable water sources on the route.
Trekking poles
Helpful for balance on scree and to reduce knee strain during descent.
Common Questions
How difficult is the hike to Cerro Colorado?
It’s a moderate day hike—expect sustained uphill walking with some loose scree near the summit; no technical climbing is needed.
Do I need a guide or can I hike independently?
Local guides add safety and interpretation and this tour includes hotel pickup; independent hikers can attempt the route but should have good route-finding skills and local weather knowledge.
What is included in the tour price?
The guided full-day tour typically includes hotel pickup and guiding; check the provider for specifics and what personal items you should bring.
When is the best time of year to go?
Southern summer (December–February) offers the most stable weather and longest daylight, though spring and fall also provide excellent conditions.
Is there cell service on the trail?
Expect patchy service—good reception near town but limited on exposed ridgelines; plan accordingly for emergencies.
Are there age or fitness restrictions?
Tours usually recommend participants be in good physical condition and able to handle several hours of uphill hiking; check with the operator for specific restrictions.
What to Pack
Sturdy hiking shoes, wind shell and insulating layer, 2–3 liters of water, sun protection (hat + sunscreen)

Quick Travel Tips
Fly into Aviador Carlos Campos (Chapelco) airport; book morning departures to avoid afternoon wind; carry local cash for small purchases; let your hotel know your return time if you’re booking independently
Local Flavor
After the hike, head to Avenida San Martín for wood-fired trout, artisanal chocolates, and a local craft beer—many restaurants source trout from nearby lakes and the town has a lively post-hike scene.
