Fodor's Expert Review Fort Reno Park

At 429 feet above sea level, the highest point in Washington has been used in different eras as a Civil War fort, the site of telegraph and radio towers, and a reservoir. In 1864, outnumbered Union troops defended the capital from a formidable Confederate advance led by General Early, in the only battle to take place in the capital. Today, the park is enjoyed by soccer players, dog-park regulars, and picnickers. Most of the Civil War–era earthworks are gone, and two curious faux-medieval towers, built in 1929, mark the reservoir site, which is not accessible to the public. Nonetheless, the park has an appealing city view and plenty of room to run around. A popular, free outdoor concert series takes place every summer featuring many of the area's most esteemed indie-rock acts, from The Owners to SleepMarks to My Sonic Daydream.
