One of the best things in Rockville are the parks. One of the best things near Rockville are the parks–and one of the best is Brookside, a county-owned horticultural garden just a few miles south of town near Glenmont. It features a variety of garden types, including Japanese, walled, rose, and naturalistic and while it’s fun to visit throughout the year, spring brings out a long display of flowers. Right now, the daffodils and cherry trees are at peak but will soon be followed by tulips and azaleas. If you visit on the weekends, I recommend arriving before 11 am (gates open at sunrise). Don’t forget that enjoying nature isn’t a luxury, it’s essential for mental fitness.
At some point in the season, they have a butterfly exhibit that is outstanding.
