1. A brief overview of Tam Diep Pass Thanh Hoa
1.1. Where is Tam Diep Pass?
Tam Diep Pass Thanh Hoa lies on the natural border between Thanh Hoa and Ninh Binh provinces, serving as a crucial pass connecting the North and Central regions of Vietnam. This area features three mountain ranges extending from the old Hoa Binh (now Phu Tho) region, creating a landscape that is both rugged and majestic. Where the rocky mountains descend, passes are formed, and because there are three consecutive passes, ancient people called it "Tam Diep" (Three Passes).

On the ancient Thien Ly road connecting Thang Long with the southern lands, Tam Diep Pass Thanh Hoa was once a crucial pass with strategic significance in both trade and military affairs. With its location between the North and Central regions, this place became an important connection point that most ancient roads had to pass through, making Tam Diep Pass a strategic gateway playing a special role in the history of trade and national defense.

At the summit of the pass, there is still a stone stele inscribed with a poem by King Thieu Tri in 1842 with the inscription "Qua Tam Diep Son", as evidence of the importance of this land in the eyes of the ancient court. Besides that, traces such as Don Dau rampart or Tam Diep ancient citadel still quietly exist through time, telling the story of a land that has witnessed many ups and downs in the nation's history.

2. Exploring the terrain and scenery at Tam Diep Pass Thanh Hoa
2.1. The system of three famous passes: Middle Pass – North Pass – South Pass
Mentioning Tam Diep Pass Thanh Hoa brings to mind three adjacent passes, winding around the mountainside like three green silk ribbons connecting the lands of Thanh Hoa and Ninh Binh. From North to South, they are successively the North Pass, Middle Pass, and South Pass. These are three natural "gateways" that possess geographical value and create a solid defense posture along with the most unique landscape in the North Central region.
North Pass is the starting point of the Tam Diep mountain range, about 75 - 80 m high, offering a clear view towards the land of Ninh Binh. Next is the Middle Pass, about 110 m above sea level, considered the highest peak, where white clouds drift around the mountainside and the valley appears hazy in the early mist. Finally, there is the South Pass, about 80 - 90 m high, located near the center of Tam Diep, likened to a gateway leading into the fertile land of Thanh Hoa, rich in historical imprints.
2.2. Impressive natural scenery throughout the 4 seasons
Each season of the year, Tam Diep Pass Thanh Hoa dons a unique beauty, making anyone passing by stop and admire it. The winding road around imposing limestone mountains, with white reeds swaying in the wind on both sides, creates a scene that is both wild and poetic. When spring arrives, the fresh green of the forest combines with vast pineapple hills, dotted with fruit orchards laden with fruit, bringing a sense of peace and prosperity.
In summer, golden sunlight covers the mountainside, reflecting on the forest canopy, sparkling like silver. As autumn arrives, early morning mist drifts hazily, clouds drift leisurely over the passes, creating a mystical scene perfect for those who love cloud hunting, photography, and sunset viewing. In winter, Tam Diep Pass Thanh Hoa becomes quieter, the chilly atmosphere makes the scenery more profound, like a nature painting slowly changing colors over time.

3. Typical cultural and historical values in the Tam Diep Pass area of Thanh Hoa
3.1. Ba Doi Stele House
Located on the southern mountainside of Tam Diep Pass in Thanh Hoa, the Ba Doi Stele House is one of the typical historical relics of this land. The structure was erected in 1842 when King Thieu Tri visited Tam Diep during a royal tour and composed the poem "Passing Tam Diep Mountain" inscribed on the stone stele. The poem expresses pride in the nation's grandeur and the Nguyen Dynasty's strategic vision for protecting the country's borders.
After nearly two centuries, the stele still stands majestically amidst the mountains and forests, like a silent witness to history. In 1984, when traces of the old stele house foundation were discovered, the structure was restored to its original location, allowing visitors today to personally admire the ancient stele, reread King Thieu Tri's poem, and clearly feel the breath of time emanating from every carving and moss-covered trace. Amidst the tranquil space of Tam Diep mountain, the Ba Doi Stele House appears solemn, like a reminder of the glorious past of this heroic land of Thanh Hoa.
