The most heavily developed of the three ranger districts, the Sacramento district has 10 developed campgrounds and 5 group-camping sites. Three areas, James Canyon, Upper Karr Canyon, and Lower Karr Canyon are free. Upper Karr is open year-round, while the others are generally open from May to September, weather permitting. Popular day-use picnic sites include the Trestle Recreation Area near Cloudcroft, and Bluff Springs, a partially developed area near a scenic waterfall. There are more than 50 trails within the district to challenge hikers of all skill levels. Many of these trails explore small canyons, lead to natural features, such as waterfalls and springs, and follow the abandoned beds of the railroads that once hauled timber from the high forests down the desert floor. While the majority of these trails are shorter than 3 miles in length, the Sacramento district has several long multi-day backpacking trails, including the 29-mile long Rim Trail (T105). The district also includes the 5-mile long Dog Canyon National Recreation Trail, which begins immediately west of the forest in Oliver Lee Memorial State Park, south of Alamogordo and climbs over 3000 ft to the heart of the forest. Guadalupe Ranger District The most remote of the three ranger districts, the Guadalupe district only has one developed facility, Sitting Bull Falls Picnic Area. An oasis in the desert located approximately 20 miles west of Carlsbad, Sitting Bull Falls has covered picnic tables, fire grills, water, restrooms, and access to a number of trails, including a .5 mile trail (T68A) to the 150-ft. Sitting Bull Falls. This is a day-use facility only, with no camping allowed. The district has 23 developed trails, most of which are 3 miles in length or less. These trails can be found in all parts of the district, from the deep canyons in the south to the rolling hills further north and range from easy to difficult. The majority of these trails are also open to pack and service animals. Neither mechanized or motorized vehicles are allowed on the trails in the Guadalupe district, though OHV's are allowed on most forest roads. Scenic drives in the district include an approximately 50-mile trip west from Carlsbad on N.M. 137 to 5 Points Vista, a scenic overlook with views of the Guadalupe Mountains and the Rim, the 1500' - 2000' cliff that extends the entire north–south length of the district and which marks the western
