Fodor's Expert Review Tam Dao Hill Station

Tam Dao's main attraction lies in its elevation and subsequent cool temperatures: it's a nice way to beat the heat of Hanoi, and the hiking is fair. Don't expect much in the way of information on trails, however, unless you have organized a tour with one of the better Hanoi tour operators. Few people, even locals, realize that Tam Dao and the surrounding peaks are in a national park, which may be one reason why logging and poaching remain a problem for the area (some of the restaurants here list supposedly protected animals on their menus). But for the most part, a hike up to the radio transmitter above the town is a walk into dense jungle. Small Buddhist temples line the concrete steps up to the tower, and a spring bubbles up from beneath the underbrush and splays out into a small waterfall. If you're spending the night up in these mountains, bring a sweater and some rain gear. People have been known to ride mountain bikes up to Tam Dao and spend the night, but the climb is extreme (a 10% gradient over long stretches). Less-active riders put their bikes in minivans on the way up and then careen down the extremely winding and dangerous—but ultimately exhilarating—route to the base of the mountain.
