Golestan Palace, a UNESCO World Heritage site in Tehran, offers a captivating glimpse into Qajar-era Persian art and architecture, blending traditional Persian crafts with Western influences. The complex is largely accessible with well-maintained courtyards, though some palace interiors involve stairs; comfortable shoes are recommended for exploring the extensive grounds. While enjoyable solo with information boards, a guided tour significantly enhances the experience by providing rich historical and cultural context. The palace is open year-round, but spring and autumn (March-May, September-November) offer the most pleasant weather, avoiding the intense summer heat. Expect to spend approximately 2-4 hours for a comprehensive visit. Entrance fees vary by section, totaling around $10-$20 USD for foreigners to access key areas, which can be paid in Rial. Visitors should adhere to Iran's modest dress code, and be aware that while general photography is allowed, some specific interiors may have restrictions; early morning visits are advisable to avoid crowds.
