The Chalus Road is a 190-kilometer mountain highway connecting Tehran, Iran's capital, to the Caspian Sea coastal town of Chalus. The road climbs through the Alborz Mountains, reaching elevations above 3,000 meters before descending dramatically through lush Hyrcanian forests—an ancient forest ecosystem recognized as a UNESCO World Heritage Site—to the subtropical Caspian coast.

Built during the reign of Reza Shah in the 1930s, the Chalus Road is one of Iran's most famous and heavily traveled routes, especially on weekends and holidays when Tehranis escape to the Caspian seaside. The road features a remarkable series of tunnels, bridges, and viaducts carved through steep mountain terrain. The contrast between the arid, brown southern slopes near Tehran and the verdant, misty northern forests is striking, and the descent through ancient beech and oak forests with their dense green canopy feels like entering another world entirely.

Where is it?

Chalus Road is located in Alborz Province, Iran (asia). Coordinates: 36.2000, 51.2000

Driving Tips

Avoid Friday and holiday traffic when the road becomes extremely congested. Drive south to north for the most dramatic scenery reveal. The old road is more scenic than the newer freeway sections. Stop at the Veresk Bridge area for mountain views. Autumn foliage in the Hyrcanian forests is spectacular. Carry warm clothing as temperatures drop significantly at the summit.

Ho Chi Minh Road (Western Branch)

🇻🇳 Vietnam

The Ho Chi Minh Road is a modern highway that follows much of the route of the legendary Ho Chi Minh Trail, the wartime supply network that ran through the jungles and mountains of central Vietnam, Laos, and Cambodia. The western branch of the road stretches roughly 1,200 kilometers from Hanoi to Ho Chi Minh City through the Truong Son (Annamite) mountain range, far from the busy coastal Highway 1. This route passes through some of Vietnam's most remote and stunning landscapes, including Phong Nha-Ke Bang National Park with its enormous cave systems, the DMZ (Demilitarized Zone) region, the A Shau Valley, and dense tropical forests that still show bomb craters from the American War. The road sees very little tourist traffic, offering an authentic journey through rural Vietnamese life with minority hill tribe villages, waterfalls, and sweeping mountain vistas. Sections are beautifully smooth tarmac cutting through pristine jungle, while others are rougher and more adventurous.

Mae Hong Son Loop

🇹🇭 Thailand

The Mae Hong Son Loop is a legendary 600-kilometer motorcycle and driving circuit in northern Thailand that winds through the mountainous terrain between Chiang Mai and Mae Hong Son provinces. The route features an astonishing 1,864 curves as it passes through lush tropical forests, terraced rice paddies, hill tribe villages, and misty mountain passes along the Myanmar border. The loop can be driven in either direction and typically takes 3 to 5 days to complete at a leisurely pace. Highlights include the town of Pai with its laid-back atmosphere, the fish cave at Tham Pla, the hot springs at Tha Pai, and the stunning viewpoints above the cloud-filled valleys. The road reaches elevations of around 1,500 meters and provides an authentic glimpse into rural northern Thai life far from the tourist beaches.

Khardung La Passextreme

Khardung La Pass

🇮🇳 India

Khardung La is a mountain pass in the Ladakh region of the Indian union territory of Jammu and Kashmir. At approximately 5,359 meters (17,582 feet) above sea level, it is one of the highest motorable passes in the world and serves as the gateway to the Nubra and Shyok valleys. The 39-kilometer road from Leh to the pass summit climbs steeply through a barren, high-altitude landscape of rocky terrain and snowfields. The pass was originally built in 1976 and opened to public motor vehicles in 1988. It is maintained by the Border Roads Organisation and remains a bucket-list destination for adventure motorcyclists and overlanders from around the world. The thin air at the summit can cause altitude sickness, and weather conditions can change rapidly with snow possible even in summer months. The views from the top are breathtaking, with panoramic vistas of the Karakoram range stretching into the distance.

Halsema Highwayhard

Halsema Highway

🇵🇭 Philippines

The Halsema Highway (officially Aspiras-Palispis Highway) is the highest road in the Philippines, reaching an elevation of approximately 2,255 meters as it traverses the Cordillera Central mountain range in northern Luzon. The 150-kilometer route connects Baguio, the summer capital of the Philippines, to Bontoc in Mountain Province, winding through dramatic mountain scenery of pine forests, vegetable terraces, and deep ravines. Named after the American engineer Eusebius Halsema who supervised its construction in the early 1900s, the road is notorious for landslides, fog, and narrow sections with steep drop-offs. Despite improvements over the years, it remains a challenging drive that passes through the spectacular rice terraces of the Cordillera region, a UNESCO World Heritage Site. The highway provides access to remote Igorot communities whose traditional culture and terracing skills have been maintained for over 2,000 years.
