In the misty hills of Doi Pui, the Hmong people once ruled the opium trade, their secret trails winding through lush forests from Doi Pui to Ban Mae Sa Mai and Ban Mae Sa Noi
You are a Hmong scout in 1870, tasked with foiling a conspiracy threatening the ancient trade routes connecting Doi Suthep to the Chiang Mai plain.
Your mission begins at Tha
Uncover the ancient secrets of Chiang Mai, where the old city walls whisper tales of opium routes and forgotten kingdoms.
Your quest begins at Tha Phae Gate, the eastern gate of Chiang Mai's old city, built in 1870 during the reign of King Chao Chettharat Ratcha. This gate, an integral part of the 3 km brick ramparts originally erected in the 13th century by King Mangrai, was restored in 1960 to preserve the Lanna fortifications. Standing approximately 10 meters high, it remains an iconic starting point for exploring Lanna heritage and the region's historic routes. It is here that the first clues of the conspiracy reveal themselves, hidden within the ancient stones of this entrance to the city's heart.
Continuing your journey, you reach Wat Phra Singh Woramahawihan, a royal temple built in 1345 by King Phayu, housing the 14th-century Phra Buddha Sihing statue. This 3-hectare complex, located less than 1 km from Tha Phae Gate, is a key site for understanding the history of Chiang Mai. The golden viharn, rebuilt in 1886, with its frescoes illustrating Lanna legends, offers valuable information. Your 1.5 km route then takes you near Warorot Market, a commercial hub where the exchange of goods and information has always been intense, a strategic place to gather rumors about the opium routes.
The path leads you to the Three Kings Monument, erected in 1935 in honor of Mangrai, Ramkhamhaeng, and Ngam Muang, founders of Chiang Mai in 1296. Located in the center of the old city, 1 km from Tha Phae Gate, this monument symbolizes the Lanna alliance of 1292. The 2-meter statues of the three kings remind you of the importance of unity in the face of threats. Nearby, Wat Chedi Luang, founded in 1335, with its 80-meter main chedi (partially collapsed in 1596), was once a royal elephant residence and a place of power expanded by King Tilokarat. These sites are crucial milestones in your investigation into the conspiracy of the historic Doi Suthep routes.
Exploring the rich Lanna heritage, you traverse the old city of Chiang Mai, where every alley and building tells a part of its story. The Chiang Mai Provincial Hall, though more recent, symbolizes the continuity of administrative power in the region, a place where decisions influencing trade routes and Hmong villages have been made over centuries. Your itinerary then takes you to the Chiang Mai National Museum, where artifacts illustrate the cultural depth and historical ties of the region to the Doi Suthep hills, particularly through the opium routes and the 20m high golden main chedi, visible from the surrounding hills, rebuilt in 1930.
Your quest concludes at Nawarat Bridge, a historic bridge crossing the Mae Ping River in the old city, built in 1935. This 150-meter concrete bridge, connecting the east-west quarters near Tha Phae Gate, is the final point of your exploration of Chiang Mai's historic routes. By following the Mae Ping banks, mentioned in the ~3.5 km route, you have unraveled the threads of the conspiracy. You leave with a deep understanding of Chiang Mai's history, its royal temples, its 13th-century Lanna heritage, and the issues that shaped this region, from the founding kings to the Hmong people involved in the opium routes.
