The world's largest living Christmas tree is a grand fir tree in Coeur d'Alene, Idaho. This tree, which is 162 feet tall, is located at The Coeur d'Alene, a resort on the shores of Lake Coeur d'Alene.
The Coeur d'Alene living Christmas tree is decorated with more than 40,000 LED lights connected by two miles of electrical wiring. Fortunately, the LED lights use 90 percent less energy than conventional light bulbs. The star that tops the tree is more than 10 feet tall.
Coeur d'Alene's grand fir is more than twice as tall as New York’s famous Rockefeller Center Christmas tree, which is 76 feet tall. The Guinness record for the largest live Christmas tree is held by a 221 foot Douglas fir that was located near Seattle's Northgate Shopping Mall in the 1950s.
