Light pollution is a growing issue that has led to the creation of the dark sky movement, which aims to preserve and protect dark sites through responsible lighting policies and public education. The International Dark Sky Places program certifies communities, parks, and protected areas worldwide that are dedicated to reducing light pollution. These places offer a quality nighttime experience, allowing people to connect with nature and enjoy the night sky. While it's challenging to find places with no light pollution, several destinations worldwide provide dark skies ideal for stargazing and astronomy enthusiasts.

What You'll Learn
National parks in the US
National parks are often situated in some of the most remote areas of the United States, which helps preserve the quality of the night sky by protecting these places from light pollution. Dozens of national parks around the country have been designated as International Dark Sky Parks and Sanctuaries by the International Dark-Sky Association. These designations recognise the quality of starry nights and the nocturnal environment that is specifically protected for its scientific, natural, educational, cultural heritage, and/or public enjoyment.
Big Bend National Park, Texas
Big Bend National Park is one of the most remote places in America, located about a six-hour drive from San Antonio, the nearest city. It has the least light pollution of any other National Park unit in the lower 48 states, and its dark skies make it one of the best places in North America for stargazing. On a clear night, one can see approximately 2,000 stars from this park.
Death Valley National Park, California
Death Valley National Park is the largest Dark Sky-designated area, spanning 13,700 square kilometres. The park boasts extreme landscapes and salt flats that serve as wonderful viewing locations for its night skies. The park's cool nighttime temperatures make stargazing even more appealing.
Joshua Tree National Park, California
Joshua Tree National Park offers visitors the opportunity to admire the Milky Way, especially for those residing in the greater Los Angeles area. While the western half of the park is impacted by light pollution from Palm Springs, visitors who venture to the eastern wilderness area are rewarded with some of the darkest night skies in the region.
Chaco Culture National Historical Park, New Mexico
Chaco Culture National Historical Park is dedicated to preserving the dark sky that the Chacoans observed a thousand years ago. Over 99% of the park has been designated as a "natural darkness zone", free from permanent outdoor lighting. This helps protect the nocturnal ecosystems that rely on darkness for survival.
Black Canyon of the Gunnison National Park, Colorado
Black Canyon of the Gunnison National Park in Colorado offers a remote location with minimal light pollution, providing a unique window to the universe.
In addition to these parks, other notable mentions include Saguaro National Park in Arizona, Curecanti National Recreation Area in Colorado, and Stephen C. Foster State Park in southeast America. These parks offer dark skies and incredible stargazing opportunities due to their limited light pollution.

Rural Tanzania
Tanzania is fortunate to have fewer lights and, therefore, very dark skies. Most of the world's population in developed countries cannot see stars from their backyards due to light pollution. However, rural Tanzania offers a different experience, with one visitor commenting that they had "never seen so many stars on a moonless night".
Tanzania's dark skies can be attributed to having fewer lights and being located near the equator, allowing almost the entire sky to be viewed in one night. The country's savannah climate also contributes to conducive stargazing conditions, with regular clear nights, especially in semi-arid regions.
To promote dark skies and astro-tourism in Tanzania, efforts are being made to map the night skies and quantify light pollution levels using the Bortle Dark-Sky Scale. This will help identify specific areas suitable for astro-tourism and scientific research. For example, an astro-tourist site at Mbozi in southern Tanzania, where the sixth largest meteorite in the world lies, could attract more tourists.
Additionally, tour and wildlife guides can be trained in basic astronomy, and telescopes can be placed in hotels and observing sites. By educating the public about energy-saving and responsible lighting practices, Tanzania can further enhance its dark skies and the wonders they reveal.
Tanzania's commitment to combating light pollution and promoting astro-tourism ensures that its rural areas remain ideal destinations for stargazers seeking to explore the universe above and connect with nature in its truest form.

Urban Night Sky Places
The dark sky movement has made significant strides in recent years, advocating for the protection of the night sky and nocturnal environments, which are naturally, culturally, and historically significant. The International Dark Sky Places (IDSP) program plays a crucial role in this effort by certifying communities, parks, and protected areas that demonstrate a commitment to preserving dark sites through responsible lighting practices and public education.
One notable example of an Urban Night Sky Place is Teton County, Wyoming, located within the Greater Yellowstone Ecosystem, the largest intact ecosystem in the contiguous United States. Here, visitors can experience a stunning night sky while being just a few miles away from urban centres.
Another Urban Night Sky Place worth mentioning is Thousand Hills State Park in northeast Missouri. This park offers a unique opportunity to enjoy dark skies while being conveniently close to the city of Kirksville.
For those seeking an urban night sky experience in Texas, Shield Ranch Barton Creek is a great choice. Nestled in the Hill Country, just 18 miles west of downtown Austin, this location provides a beautiful blend of city lights and starry nights.
Palm Beach Headland, located on the outer edge of the Sydney region in Australia, offers a similar blend of urban and natural landscapes. Visitors can enjoy the vibrant city lights while also gazing upon the Milky Way in the southern sky. Additionally, the nearby Blue Mountains provide a dazzling natural attraction for stargazers.
These Urban Night Sky Places showcase how cities and protected areas can coexist while preserving the magical experience of a starry night sky. Through responsible lighting policies and community engagement, these places inspire us to appreciate the beauty of the cosmos and the importance of protecting our universal heritage in the starry night sky.

International Dark Sky Places
The International Dark Sky Places (IDSP) program was created to provide an incentive for communities and protected places to follow in the footsteps of Flagstaff, Arizona, which was named the first International Dark Sky City in 2001. The program certifies communities, parks, and protected areas around the world that preserve and protect dark sites through responsible lighting policies and public education. As of January 2023, there are 201 certified Dark Sky Places globally, spread across 22 countries on 6 continents.
There are five types of designations: International Dark Sky Communities, Parks, Reserves, Sanctuaries, and Urban Night Sky Places. International Dark Sky Communities are legally organized cities and towns that adopt quality outdoor lighting ordinances and educate residents about the importance of dark skies. International Dark Sky Parks are publicly or privately owned spaces protected for natural conservation that implement good outdoor lighting and provide dark sky programs for visitors.
International Dark Sky Reserves consist of a dark "core" zone surrounded by a populated periphery where policies are enacted to protect the darkness of the core. These sites are established through partnerships between multiple land managers. International Dark Sky Sanctuaries are the most remote and darkest places in the world, with fragile conservation states. Finally, Urban Night Sky Places are recognized for their efforts to educate the public on the benefits of proper outdoor lighting that minimizes harm to the natural nighttime environment.
Some notable examples of International Dark Sky Places include Saguaro National Park in Arizona, Timpanogos Cave National Monument, Joshua Tree National Park, and Glacier National Park.
