Big Bend National Park, Texas
Big Bend National Park in Texas is one of the most remote places in the United States. Located in southwest Texas, it is about a six-hour drive from the nearest city, San Antonio, making it an ideal spot for stargazing with minimal light pollution. The park is renowned for its breathtaking vistas and hiking trails, offering a unique experience amidst the vast Texas landscape.
The region's naturally dry climate, high elevation, and lack of artificial lighting make it one of the darkest places in the country. The night sky in Big Bend is iconic and deeply rooted in the area's culture and history. The Greater Big Bend International Dark Sky Reserve encompasses multiple parks, communities, and protected lands on both sides of the Rio Grande, working together to preserve the night sky through improved lighting practices.
The negative impacts of light pollution on human health and ecosystems are well-documented. Excessive artificial light, particularly blue light, can disrupt the natural circadian rhythm, increasing risks for obesity, depression, sleep disorders, and other health issues. By adopting better lighting practices, the Dark Sky Reserve aims to reduce these negative consequences and protect the natural rhythm of the day-night cycle.
Big Bend National Park offers a unique opportunity for stargazers to witness the universe in all its glory. The park's remote location and dark skies provide the perfect setting for astronomy enthusiasts to explore the constellations and connect with the natural environment. The Texas Parks and Wildlife Department actively monitors sky quality through initiatives like the Sky Quality Meter (SQM) project, ensuring that Big Bend remains a haven for those seeking to escape light pollution and immerse themselves in the beauty of the night sky.

Black Canyon of the Gunnison, Colorado
With over two million acres of public land, Gunnison County in Colorado offers better visibility for stargazing than cities like Denver and Colorado Springs. The Black Canyon of the Gunnison National Park is a certified International Dark Sky Park, which means it prioritises preserving the night sky. The park uses light pollution-conscious outdoor lighting and offers nighttime public access, astronomy programs, daytime and nighttime telescope viewing, astronomy talks, and constellation tours. The North Rim is a prime place for stargazing as it sees fewer visitors. The Milky Way is most visible at the Black Canyon in the summer when the Earth's position means the canyon faces the centre of the galaxy.
The Gunnison Valley, in general, keeps light pollution low, so you can enjoy stargazing from the porch of your vacation rental or a remote spot in the backcountry. The best time to stargaze in Colorado is during the colder months of fall and winter when the skies tend to be most clear. The high altitude, low air pressure, and dry air of the region create excellent atmospheric transparency, which measures how much light from space can pass through the atmosphere.
AstroFest is an annual festival dedicated to preserving the night sky along the Gunnison River corridor. The Curecanti National Recreation Area, which is comprised of three alpine reservoirs, including Blue Mesa Reservoir, also offers excellent stargazing opportunities. Park rangers run astronomy and telescope viewing programs at the Elk Creek Campground amphitheatre.
Hartman Rocks, about a 15-minute drive from downtown Gunnison, provides expansive views of the night sky. The desert scape features rolling fields of sagebrush and otherworldly sandstone rock formations. Crested Butte, a small town in Gunnison County, is another place with little light pollution.

Rural Tanzania
Tanzania has been working on its rural electrification program since its independence in 1963. However, progress has been slow due to financial constraints and tariff policies. As a result, rural Tanzania remains one of the best places to experience a night sky with little light pollution. A user on Reddit mentions that they have "never seen so many stars on a moonless night" in rural Tanzania.
The national utility company, TANESCO, has been working to provide technical support and training to operators. The Urambo Electric Consumers Co-operative Society has demonstrated that with adequate technical, management, and financial support, villages in Tanzania can manage their own electricity supply systems.
In rural areas of Tanzania, traditional energy sources such as kerosene lamps are still commonly used for lighting and cooking. Kerosene lamps have been associated with indoor air pollution and lung diseases. A study found that only 27.6% of homes using open-wick kerosene lamps met the World Health Organization's indoor air quality standards, compared to 75% in homes using solar lighting.
Solar lamps have been promoted as a potential solution to reduce the health and environmental impacts of kerosene use. However, the transition to solar lighting in rural Tanzania has been slow, with electricity still being a scarce resource in many areas. As a result, rural Tanzania continues to offer some of the darkest skies for stargazers and astronomers to observe the night sky in all its glory.
If you're planning a trip to Tanzania specifically for stargazing, keep in mind that the country offers some of the darkest skies in the world due to its low light pollution levels in rural areas. You may want to consider visiting popular stargazing destinations such as Colorado or Big Bend in the United States, which are known for their dark skies and stunning landscapes. However, with its vast expanses of untouched nature and lack of artificial lighting, rural Tanzania promises a unique and unforgettable stargazing experience.
