Most any time of the year is an excellent time to visit Lee, Massachusetts. Given its location near to the Berkshires, springtime is an excellent time to experience the blooming wildflowers and if fall foliage is your thing, then you'll want to visit Lee during the autumn when the tree's changing leaves are at their peak. Summertime is a great time for hiking, biking, rafting, and other outdoors activities. During the summer, you can also catch one of several concerts at Tanglewood, the summertime home of the Boston Symphony Orchestra, which is located quite near to Lee. If you're more a winter sports fan, then you'll want to consider heading to the region during the cold weather months, when you can catch some great skiing (both alpine and cross-country) at the nearby ski resorts.
