There are so many places to visit in April. But top on my list is Washington, DC for the National Cherry Blossom Festival. There are over 3,000 cherry blossom trees in the capital. This year, the festival is from March 20 to April 14. Cherry blossom peak bloom days vary from year to year. NPS actually has the peak bloom forecast. Bluebonnets are in full bloom in Austin and the Texas Hill Country till mid-April. If you want to experience Dutch Heritage and a tulip festival, check out Holland (Michigan) , Michigan.
