Founded in 1934, The Sarah P. Duke Gardens offers 55 acres (22 hectares) of world-class gardens in the center of Duke University. More than five miles (eight kilometers) of pathways lead visitors on walks through four sections of beautifully landscaped terraces, gardens, and arboretums. The Duke Gardens host gardening, photography, and natural history classes, and a summer concert series. A cafe and a visitor center are on the grounds. Walking and trolley tours are given four days a week; reservations are recommended.
If you're looking to enjoy the great outdoors while in Raleigh, definitely pay a visit to Lake Wheeler. You'll see people bringing their boats or renting boats for some leisurely fishing and cruising. Bring a picnic to enjoy on a boat or on land. Take a lovely stroll or jog on the winding trails in the park. The lakefront location has benches too, so you can steal a quiet moment in the park. Other facilities include rowing, kayaking, canoeing and sailing.
