1. The MacDonnell Ranges are a mountain range located in central Australia, near the town of Alice Springs. They stretch for approximately 644 kilometers and are divided into two sections - the West MacDonnell Ranges and the East MacDonnell Ranges. The ranges are known for their stunning natural beauty and are a popular destination for tourists and outdoor enthusiasts.

The West MacDonnell Ranges feature breathtaking gorges, waterholes, and rock formations, including famous sites such as Standley Chasm, Simpsons Gap, and Glen Helen Gorge. The East MacDonnell Ranges are less visited but offer equally impressive landscapes, including Trephina Gorge and Emily Gap.

Visitors can explore the ranges by hiking the various trails that wind through the national parks in the area. These trails offer incredible views of the rugged terrain, vibrant red cliffs, and unique flora and fauna, including native wildlife such as kangaroos and rock wallabies.

2. The MacDonnell Ranges can be visited at any time, as they are open 24/7. There is no specific entrance fee or working hours, as they are a natural attraction accessible to the public. However, some of the national parks within the ranges may have visitor centers with specific opening hours and may require a small entrance fee.
