Simtokha Dzong, a historic fortress and monastery located just south of Thimphu, is easily accessible by road, typically a short taxi ride from the city center. While the internal structure involves some walking and stairs, it's generally manageable for most visitors. Tourists visiting Bhutan are usually required to have a licensed guide, who will accompany them to the Dzong, enriching the experience with historical and cultural insights, though independent exploration within the grounds is also possible. The Dzong is open year-round, with spring and autumn offering the most pleasant weather, though it remains accessible during the monsoon. There isn't a direct entry fee as access is covered by Bhutan's mandatory daily Sustainable Development Fee (SDF). A typical visit lasts approximately 1 to 2 hours. Visitors should wear modest clothing covering shoulders and knees out of respect for the active monastic institution; photography is generally permitted in courtyards but often restricted inside temples, and it provides excellent panoramic views of the surrounding valley.
