3. _Ceremonial Cave_ is reached by trails either along the Rito or along the north cliffs, approximately 1 mile above headquarters. A walk to this cave is very popular with hikers of modest ambitions, and is particularly rewarding to the photographer. There are a number of tall ladders to climb to reach the cave; consequently, rubber-soled shoes and a degree of caution are recommended. 4. The _Upper Falls_ are downstream from headquarters about a mile and a half. The trail follows the Rito down through some of the handsomest forest glades on the monument, crossing the stream several times. The falls, in a deep lava cleft, are about 80 feet high. The _Lower Falls_, a quarter-mile farther down, are only half as high. Along the trail between the two falls, a geologically interesting exposure of the canyon wall is conspicuous. OTOWI SECTION. Two large ruins, Tsankawi and Otowi, are the principal features to visit on this detached section of the monument. The main access road from Santa Fe to monument headquarters passes through this section and close to the Tsankawi Ruin. Distance from this ruin to headquarters is 16 miles. 5. _Otowi Ruin_ lies between Pueblo and Bayo Canyons on a disused road. Inquire of a park ranger before attempting to make the trip. 6. _Tsankawi Ruin_ is reached by a spur road and foot trail branching from State Route 4. At the end of the road, a stand contains booklets for the self-guiding trail which leads up onto the mesa to the ruins, a round trip walk of about three-quarters of a mile. THE BACK COUNTRY. A network of some 50 miles of foot and horseback trails reaches out from monument headquarters into the roadless southern areas of the monument. Hikers and horseback parties frequently make a loop trip of 2 days, visiting the Stone Lions and Yapashi Ruins, and spending the night at Base Camp in Capulin Canyon, where a National Park Service fire guard is on duty during the summer. The return trip may be made past Painted Cave to the Rio Grande, then up White Rock Canyon to Frijoles Canyon and point of beginning. [Illustration: _Frijoles Canyon Lodge, one of several verdant patios._] ADJACENT POINTS OF INTEREST. The _Valle Grande_ is 15 miles west from the Frijoles Canyon checking station, on State Route 4, toward Cuba, N. Mex. This drive across the Jemez ridge cannot be made in the winter, for the road is never cleared of snow. _Los Alamos_, the atomic city, borders the monument on the north. At the time of this writing (1955), visitors are not allowed to enter the gates of Los Alamos without special passes.
