Sikkim is a beautiful state in the Himalayas, and it is a popular tourist destination. However, the state is also very mountainous, and this can make it difficult to access some of the most popular tourist attractions. In recent years, the government of Sikkim has made a number of efforts to improve accessibility for tourists. These efforts include:

  • Road and highway development: The government has built new roads and highways to connect remote villages and tourist destinations. This has made it easier for tourists to get around the state.
  • Helicopter services: The government has also started helicopter services to some of the most remote tourist destinations. This is a great option for tourists who want to see the best of Sikkim without having to hike or drive for hours.
  • Construction of ropeways: The government has also constructed ropeways to some of the most popular tourist destinations. This is a great option for tourists who want to get a bird’s eye view of the state without having to hike or drive.

These efforts have made it much easier for tourists to visit Sikkim. As a result, tourism in the state has increased significantly in recent years.
