In an era defined by glowing screens, illuminated highways, and sprawling city lights, the simple act of looking up at a star-filled sky has become increasingly rare. Artificial light pollution has washed out the night sky for much of the world, obscuring the Milky Way and diminishing our ability to see constellations that guided humans for thousands of years. As a result, dark sky areas—locations that intentionally preserve natural nighttime darkness—have grown in importance. These places offer refuge for astronomers, photographers, outdoor enthusiasts, and travelers searching for meaningful encounters with the cosmos.
This article explores what makes dark sky areas significant, why they are critical to ecological and cultural preservation, and highlights two of the country’s most remarkable dark sky destinations: Moab, Utah and Great Sand Dunes National Park in Colorado. Both locations offer world-class stargazing, community-driven conservation, and unforgettable nighttime landscapes.
Dark sky areas are locations where artificial light is minimized or carefully controlled to protect the natural darkness of the night. They exist in response to a growing challenge: light pollution.
Light pollution refers to excessive or poorly designed artificial lighting that brightens the night sky. Its impacts include:
Skyglow: A dome of light over cities and suburbs that obscures stars
Ecological disruption: Confusion of nocturnal wildlife, disrupted migration, altered feeding patterns
Human health effects: Poor sleep and circadian rhythm disruption
Astronomical interference: Reduced visibility for research and stargazing
Because of these impacts, organizations such as the International Dark-Sky Association (IDA) advocate for the creation of dark sky parks, communities, and preserves.
To earn IDA recognition, a location must:
Maintain exceptionally low levels of light pollution
Implement responsible outdoor lighting standards
Protect nighttime visibility through community policy
Offer public outreach and education
Demonstrate long-term commitment to conservation
These designations help communities attract responsible tourism, promote environmental stewardship, and protect the beauty of the night sky for future generations.
Dark sky areas offer much more than beautiful nighttime scenery. Their impact spans science, ecology, culture, and recreation.
Professional and amateur astronomers rely on dark skies to observe:
nebulae
star clusters
distant galaxies
meteor showers
planetary alignment events
In a world where urban glare increasingly limits visibility, dark sky regions preserve the clarity necessary for meaningful astronomical study.
Artificial light disrupts natural biological cycles. Dark sky protections help safeguard:
nocturnal mammals such as foxes, bats, and coyotes
migrating birds that navigate by starlight
insects drawn off-course by artificial glow
desert ecosystems that depend on natural light cycles
By preserving natural darkness, dark sky areas support healthier, more balanced ecosystems.
For millennia, humans have relied on the night sky for:
navigation
storytelling
spiritual meaning
scientific discovery
In dark sky areas, visitors regain access to the same star-filled sky experienced by ancient civilizations. This connection fosters awe, reflection, and a renewed sense of wonder.
Astrotourism is one of the fastest-growing sectors of outdoor travel. Visitors seek destinations where they can:
see the Milky Way clearly
photograph colorful night skies
attend astronomy programs
enjoy nighttime hikes and ranger-led tours
Communities benefit economically while preserving a priceless natural resource.
Moab has long been known for its red rock landscapes, outdoor recreation, and proximity to iconic national parks. But in recent years, it has also emerged as one of the most sought-after dark sky destinations in the United States.
In 2020, Moab earned official certification as an International Dark Sky Community. This recognition reflects:
The city’s dedication to minimizing light pollution
Adoption of responsible lighting ordinances
Public education on dark sky preservation
Continued collaboration with Arches and Canyonlands National Parks
This combination of local action and natural geographic advantage makes Moab one of the most accessible dark sky experiences in the American Southwest.
Several factors contribute to Moab’s world-class stargazing conditions:
With fewer urban light sources, the surrounding desert remains remarkably dark.
Southeastern Utah’s arid environment provides:
minimal cloud cover
low humidity
high transparency and clarity
These conditions allow for vivid views of the Milky Way and other celestial features.
Higher altitude reduces atmospheric interference, making stars appear sharper and brighter.
Natural arches, sandstone towers, and sweeping desert vistas create unforgettable compositions for night photography.
After sunset, this iconic park transforms into a stargazing sanctuary. Popular locations include:
Balanced Rock
The Windows Section
Panorama Point
Devils Garden Trailhead
Visitors often enjoy crystal-clear Milky Way views framed by natural stone arches and monolithic rock formations.
Canyonlands offers some of the darkest skies in the lower 48 states. Highlights include:
Mesa Arch (Island in the Sky)
Grand View Point
Green River Overlook
Ranger-led night sky programs deepen the experience with telescope viewing and constellation interpretation.
Moab hosts various astronomy festivals and star parties that bring together novices, experts, and curious travelers.
While Moab often steals the southwestern spotlight, Great Sand Dunes National Park and Preserve in southern Colorado is equally deserving of dark sky prestige—and is rapidly gaining recognition as an extraordinary stargazing destination.
In 2019, Great Sand Dunes earned certification as an International Dark Sky Park, cementing its reputation as one of the best nighttime environments in North America.
Great Sand Dunes’ unique geography creates a setting unlike any other dark sky location.
The park contains the tallest dunes in North America, some rising over 750 feet. These massive dunes absorb light and create an exceptionally dark horizon.
Bordering wilderness areas and far from urban centers, the park benefits from minimal surrounding light pollution.
Located in the vast San Luis Valley and bordered by the Sangre de Cristo Mountains, the region’s vast openness contributes to expansive sky views.
The valley’s low humidity and frequent clear nights ensure optimal stargazing conditions throughout the year.
Hiking the dunes under starlight offers an ethereal experience. The sand holds heat from the day and releases it slowly, creating comfortable nighttime conditions.
From late spring through fall, the Milky Way arches spectacularly over the dune field, attracting photographers from around the world.
These designated viewing areas offer wide-open dark skies without the need to trek deep into the dunes.
Park rangers host seasonal astronomy events, featuring:
telescope viewing
constellation tours
educational talks on preserving night skies
Darkness is an essential part of the park’s ecosystem. Nocturnal animals—including kangaroo rats, owls, bats, and foxes—depend on natural darkness for hunting, migration, and survival. The park works diligently to:
Replace outdated lighting
Implement fully shielded fixtures
Maintain low-light environments in visitor areas
Culturally, the night sky has long been significant to the region’s Indigenous communities, who used the stars for navigation, storytelling, and ceremonial traditions.
Although distinct in landscape—one defined by sandstone arches, the other by towering dunes—Moab and Great Sand Dunes share:
Devotion to dark sky preservation
Rich opportunities for stargazing
Thriving communities committed to education
Significant ecological value
Growing appeal for adventure travelers
Both destinations demonstrate how preserving natural darkness enriches both human experience and environmental health.
Dark sky areas like Moab, Utah and Great Sand Dunes National Park remind us what it means to truly experience the night. They preserve:
the brilliance of the Milky Way
the natural rhythms of wildlife
opportunities for scientific discovery
cultural and spiritual connections to the universe
As light pollution continues to increase worldwide, the importance of these protected regions becomes clearer. They are sanctuaries—places where anyone can step away from modern glow and rediscover the overwhelming beauty of the dark.
