Hoa Binh province
Hoa Binh province is the gateway to Vietnam's northwest, strapped around the foothills of the mountains that run up from the plains. Well regarded for the trekking centre of Mai Chau, this province and it's same-named capital, Hoa Binh, is a popular option with Hanoi-based travel agents who don't want to take their passengers too far.
The province is best known for the large reservoir which runs through its centre, and which was formed by the damming of the Song Da river. The river strikes to the northwest of Hoa Binh, well into Lai Chau province. Dammed for hydro-electric purposes almost 200 workers died during its construction and there's a monument to their memory at the dam site.
Few independent travellers choose to spend much time in this province. It's not really far enough away to shake the chaos of Hanoi, and the scenery, while pretty, is far more impressive further out. If you're travelling under your own steam either Hoa Binh or Mai Chau make for convenient spots to break the journey -- but our vote would certainly go for Mai Chau if you were tossing up the two.
