The Kalon Tower, a UNESCO World Heritage site and a prominent feature of Bukhara's Poi Kalyan Complex, is generally accessible on foot within the Old City, though climbing its internal narrow, steep stairs requires a separate fee, typically a few USD. While visitors can explore solo, a local guide provides invaluable historical and cultural context, enriching the experience significantly. The tower is open year-round, but the most comfortable seasons for visiting and climbing are spring (April-May) and autumn (September-October) to avoid the extreme heat of summer or the chill of winter. A typical visit to appreciate its exterior and the surrounding complex takes 30-60 minutes, with an additional 30-45 minutes needed if you choose to ascend for panoramic views of Bukhara, making it a highly recommended experience for its architectural grandeur and historical depth.
