As the weather continues to cool its prime time to get out and explore Houston's outdoors. While Hermann Park and Buffalo Bayou are obvious (and must see) destinations, a trip to Glenwood Cemetery is a unique landmark worth checking out, especially while Halloween still lingers in the air.

Founded in 1871, Glenwood Cemetery is one of Houston's unique landmarks. Situated on 84 acres along the Washington Corridor, Glenwood Cemetery serves as a serene resting place for some of Houston's most iconic residents. Among the ornate headstones are those of more than 20 mayors, past governors, oil tycoons and Howard Hughes-the famous aviator, engineer and movie director.

European landscape artist Alfred Whitaker designed the iconic site, which opened in 1871, molding the cemetery around the undulating hills created by Buffalo Bayou. Today, Glenwood draws families, the bereaved and the merely curious looking to reflect on the monuments and take in some of the most breathtaking views of Houston's skyline.

Though there are no tours specific to Halloween, the cemetery gates are open every day from 7 a.m. until 5 p.m. When Daylight Savings Time is in effect, the gate closing is extended to sunset or 6:30 p.m., whichever is earlier. There are also docent-guided walking tours available to groups or individuals by reservation.

The Glenwood office is located on the cemetery grounds and is open Monday through Friday from 8 a.m. to 5 p.m., closed on holidays.
