In Washington, the Georgetown House Tour, the oldest house tour in the country, will be April 28-29. The Georgetown Garden Day, now in its 70th year, and featuring both public and private gardens, is May 5. Highlighting this year's festival will be a series of luncheons, teas, and wine tasting. Sponsored by Historic Charleston Foundation, the festival features 150 privately owned houses in 11 historic neighborhoods. The tours are self-guided, allowing visitors to tour at their own pace.
Most tours sell out before the day of the event.
For a different view of spring, head to San Diego. There you'll find the Anza-Borrego Desert State Park, where the dry, rugged landscape is transformed by winter rains into a kaleidoscope of colorful wildflowers. The full bloom occurs now through April 30. The park is just two hours from San Diego. The hillsides of Carlsbad in North Country become quite colorful when more than 50 acres of ranunculus are in full bloom at The Flower Fields at Carlsbad Ranch.
