We will pick you up from your downtown Beijing hotel for a direct drive to Huanghuacheng Lakeside Great Wall. Upon arrival, you will enjoy a relaxed three-hour hike along various sections, exploring ancient watchtowers and beacon towers while admiring the scenic landscapes. Nestled in Huairou District about 60 km from central Beijing, Huanghuacheng is known for its unique "Water-Great Wall" where stone ramparts meet serene waters. Built in the Ming Dynasty under General Cai Kai, it once guarded the capital and imperial tombs. Its striking feature—three segments diving into and re-emerging from the lake—was created by a 1970s reservoir that partially flooded the structure. After the visit, we will return you to your Beijing hotel.
