Dong Hoi to Cat Ba: Scenic Driving Guide

Departing Dong Hoi, you trace the path of the old Ho Chi Minh Highway (QL15) before merging onto National Route 1A, the country's principal north-south artery. This route passes the 17th Parallel, the former demilitarized zone that split Vietnam from 1954 to 1976, now marked by the Hien Luong Bridge over the Ben Hai River.

Covering roughly 420 kilometers, this drive typically takes 8 to 10 hours, including essential breaks. As you approach Cat Ba, you'll eventually transfer to a ferry from Hai Phong, the last leg that sails across the emerald waters of Lan Ha Bay.

Watch for motorcycles crossing unexpectedly on QL1A; keep a safe distance. The coastal road from Nghi Son to Sam Son is scenic but has narrow sections.

For families, Vinpearl Safari in Phu Quoc is far off-route; instead, consider the Thung Nham Bird Garden in Ninh Binh for a gentle nature walk. Many restaurants offer high chairs, but signal them in advance.

• Pet-friendly stops: Several gas stations allow pet relief areas, and some homestays near Cuc Phuong National Park accept pets.
• Rest zones: Plan breaks every 2 hours; rest stops with cafes are frequent on QL1A.
• Hidden gems: Tam Coc's paddle boat tours are serene; the Hang Mua viewpoint is worth the climb.

Locals often sell fresh fruit along the road; haggling is common, and cash is preferred.

Expect to spend around 1.2 million VND on fuel for an average car. Fuel stations are abundant along QL1A, but sparser on smaller coastal roads; plan to fill up in Vinh and Hai Phong.

Toll booths on QL1A charge small fees per pass, and the ferry to Cat Ba costs about 300,000 VND per car, with schedule changes based on tide.

• Road quality: Good on QL1A, winding on coastal segments.
• Weather: November to April is cooler and drier; summers are hot and rainy.
• Car insurance: Check coverage for ferry transport.

The route links two World Heritage Sites: Phong Nha-Ke Bang National Park (near Dong Hoi) and Ha Long Bay (including Cat Ba Island). Between them lie the karst landscapes of Ninh Binh, often called 'Ha Long Bay on land' – a must-see detour if time permits.

For seafood, stop at markets like those in Vinh or Hai Phong for fresh catches.

Detour tip: 50 km east of QL1A near Ninh Binh, the Bich Dong Pagoda offers a quiet break from the main road. The local specialty, goat meat, is served in many roadside restaurants.
