The Sangre de Cristo Range offers some of the most dramatic and rewarding high-country hiking terrain in the American West. While millions of travelers journey to southern Colorado to marvel at the shifting sand hills of Great Sand Dunes National Park, an entirely different wilderness waits just beyond the dunes. Here, the landscape abruptly shifts from high-desert floor to vertical granite spires, carved out by alpine basins, thundering waterfalls, and remote glacial lakes.
For hikers looking to escape the crowds, base yourself out of Alamosa, grab your trekking poles, and connect directly with the challenge of the climb.
The Alpine Experience: Why These Trails Stand Alone
What sets the Sangre de Cristos apart from other Colorado ranges is their sheer, uncompromising verticality. Rising abruptly without foothills, these trails waste no time pushing your lungs. The transition of ecosystems here is startling. Within a single morning, you can move from pinyon-juniper woodlands up through dense aspen and douglas fir groves, breaking the treeline into wide-open glacial cirques.

1. Zapata Falls & The Lower Canyon
Nestled in a rocky crevasse near the base of the mountains, Zapata Falls drops 25 feet inside a dark, hidden cavern and is worth every step it takes (even through freezing water) to get there.
The short half-mile trail up to the stream is accessible, but reaching the waterfall itself requires wading directly into the icy snowmelt of Zapata Creek. Cold water splashes against towering rock walls as you maneuver through the mouth of the cavern and stand in awe viewing the reward of your hike. This is the perfect light trail for hikers to experience and it makes the perfect addition to a day at the Great Sand Dunes National Park.
2. South Zapata Lake
What waits for you at the end of this hike? A quiet, deep-blue alpine lake resting at 11,900 feet directly under the sheer face of Ellingwood Point. This is your sign to start planning your hike to South Zapata Lake.
Forking off from Zapata Falls trail, this long, grueling climb sees very little foot traffic. The path follows South Zapata Creek upward through thick forest and ancient pine stands before suddenly opening up into a grassy alpine meadow. Navigating rocky moraines and marshy creek crossings leads to a pristine basin where steep rock walls cradle the quiet alpine water. Bring a picnic and stay awhile or bring a tent and stay the night as you reconnect with nature in this series, secluded location.
3. Willow Lake & The Cliffside Waterfall
You are headed to one of the most photogenic alpine basins in Colorado, featuring a 150-foot waterfall plunging down a gigantic cliff directly into the lake. Willow Lake & The Cliffside Waterfall is worth each step it takes to get to it and is a bucket list experience to check off during your next visit.
Starting near the town of Crestone, the trail climbs steep, exposed switchbacks along Willow Creek. After passing through an ancient lakebed called Willow Creek Park, the final mile scrambles across boulder fields to reveal the main lake. Framed by towering 13,000 and 14,000-foot peaks, including Challenger Point and Kit Carson Peak, it is a backcountry oasis defined by the constant roar of cascading water. Push your limits and reward yourself with this incredible back country hike.
4. Lake Como & The Gateway to 14ers
A striking turquoise alpine lake that serves as the basecamp for climbing Blanca Peak, Ellingwood Point, and Little Bear Peak.
Reaching Lake Como means tackling Lake Como Road. This is widely considered the most difficult 4WD track in North America. Hikers opting to trek the road face a relentless, shade-less 4,300-foot vertical climb over loose, ankle-busting rocks before reaching the serene waters of the basin. It is recommended that only those experienced in operating a 4WD vehicle and have extensive hiking experience attempt to tackle this journey. Success in tackling this climb is incredibly rewarding however, as you sit in the serene silence, connect with nature as you disconnect from the rest of the world.
Essential Mountain Rules & High-Altitude Safety
The extreme elevation gain that makes these trails beautiful also makes them unforgiving. To return safely, keep these core wilderness practices in mind as a high priority to keep you and others hiking with you safe all the way up and back down the mountain.
- Respect the 12:00 PM Storm Threshold: Summer monsoons roll over the mountain crests quickly. Plan high-elevation hikes to begin around 4:30 AM to ensure you are off exposed ridgelines and back below treeline by noon.
- Smart Hydration & Acclimatization: Alamosa sits above 7,500 feet, and trailheads climb quickly past 11,000 feet. Spend a day in the valley before tackling big climbs, drink double your normal intake of water, and carry electrolyte powders.
- Wildlife Protocols: Carry bear spray on your pack strap where it can be reached in seconds. In the event of a mountain lion encounter, make yourself look large, stand your ground, and never run.
- Protect the Tundra: High-alpine plants take decades to grow in harsh conditions. Always stay on established trails or step only on durable rock when above treeline.

Standing on a wind-swept ridge above treeline, looking back down across the vast valley floor toward the distant dunes, you quickly realize that the Sangre de Cristos don’t offer easy views. They require early alarms, careful eyes on the sky, and grit on the switchbacks, but that’s precisely what makes every step worthwhile. Long after you’ve washed the trail dust from your gear, the quiet majesty of those high-country basins and the thrill of the ascent will stay with you and you will be itching to plan your next trip to Alamosa the second you make it back to your vehicle.
