As the gateway to Washington wine country, the Yakima Valley in the center of the state is one of the most fertile growing areas in the world. The area's 300 days of sunshine each year is key to making it an agricultural and recreational haven. The Pacific Crest Trail runs through the Valley. White Pass Ski Hill is the ultimate for snowboarders and skiers of all skill levels. The city of Yakima is proud of its professional sports teams and world-class wineries while smaller centers, like Prosser and Sunnyside, are pleased with their own agricultural contributions. Outdoor enthusiasts enjoy visiting the Columbia River Gorge National Scenic Area, which boasts a 4,000 ft (1219 m) gorge through the Cascade Mountains. Rock climbing, mountain biking, windsurfing and sightseeing are popular pastimes in this park.
