of Grand Teton lies Mount Owen, and though lower in altitude, this peak is considered more difficult to ascend. Middle Teton is another popular climb that is most easily summited from a saddle between it and South Teton. Well, north of Grand Teton lies Mount Moran, which is further from trailheads and more difficult to access and ascend. The Direct South Buttress of Mount Moran provides a vertical mile of climbing that was considered the most difficult climb in the U.S. when first accomplished in 1953. Other popular climbing destinations include Buck Mountain, Symmetry Spire, Mount Saint John, Mount Wister, Teewinot Mountain and Nez Perce Peak and each mountain has at least six established routes to their summits. Camping and hiking Grand Teton National Park has five front-country vehicular access campgrounds. The largest is the Colter Bay and Gros Ventre campgrounds, and each has 350 campsites which can accommodate large recreational vehicles. Lizard Creek and Signal Mountain campgrounds have 60 and 86 campsites respectively, while the smaller Jenny Lake campground has only 49 sites for tent use only. Additionally, full hookups for recreational vehicles are at the concessionaire-managed 112 campsites at Colter Bay Village and another 100 at Flagg Ranch in the John D. Rockefeller Memorial Parkway. Though all front-country campgrounds are only open from late spring to late fall, primitive winter camping is permitted at Colter Bay near the visitor center. All campsites accessible only on foot or by horseback are considered backcountry campsites and they are available by permit only, but camping is allowed in most of these backcountry zones year-round. The National Park Service has a combination of specific sites and zones for backcountry camping with a set carrying capacity of overnight stays per zone to protect the resources from overcrowding. Open fires are not permitted in the backcountry and all food must be stored in an Interagency Grizzly Bear Committee approved bear-resistant container. As of 2012, only four brands of bear-resistant containers had been approved for use in the Grand Teton National Park backcountry. Additionally, hikers may use an approved bear spray to elude aggressive bears. The park has of hiking trails, ranging in difficulty from easy to strenuous. The easiest hiking trails are located in the valley, where the altitude changes are generally minimal. In the vicinity of Colter Bay Village, the Hermitage Point Trail is long and considered easy.
