The two tiers of the waterfall aren't visible from the outside, but can only be heard. It's essential to walk along the edge or in the riverbed for a while. Depending on the water level, this may be possible without any slippery feet. The stones aren't particularly slippery. This river path should be avoided in winter.

Definitely worth the hike. The waterfall is hidden between the rock walls, so water shoes are necessary.

The Big Arsenic Springs Trail is a popular out-and-back trail located in the Wild Rivers Recreation Area of the Rio Grande del Norte National Monument. This trail starts at the rim of the mesa above the river, and drops quickly, descending about 600 feet down rocky, steep switchbacks to the Rio Grande. This 1.5 mile trail offers truly stunning views down the gorge as you hike. As you draw closer to the end of the trail keep an eye out for some ancient petroglyphs carved on the rocks above you. You can also link this trail with the River Trail if you wish to extend your hike.

The Slide Trail is a popular trail in the Taos Overlook area of the Rio Grande del Norte National Monument. This trail traverses on a plateau high above the Rio Grande, offering hikers stunning views down steep cliffs over the water. Although this trail is generally pretty flat, there are a few rolling hills, some loose rocks, and there can be steep drop offs to the river below so use caution when hiking. There is also little to no shade along this trail, so be sure to bring plenty of water and sun protection!

Chacos, Keens, or similar are best for hiking up to the falls. From trailhead to stream is uphill and dusty with scattered benches under trees. Navigating through the stream is short, but water is cold and watch for deep sections.

The Rio Grande Overlook provides dramatic vistas across the deep valleys carved by the river and the northern mountains. The Pecos Wilderness canyons feature impressive 100-foot-drop waterfalls and dramatic rock cliffs.
The terrain varies significantly. You'll find high-country elevations ranging from 8,400 feet to over 13,000 feet, with heavily forested slopes and rugged ridges. Canyons like those in the Pecos Wilderness feature crumbled talus slopes and dramatic rock cliffs. Trails such as the Big Arsenic Trail involve rocky, steep switchbacks, while others like The Slide Trail are generally flat with some rolling hills and loose rocks, often with steep drop-offs.
Yes, the Taos Box of the Rio Grande Gorge is a premier whitewater rafting destination. It's known for its challenging rapids, with sections categorized as Class IV in the 15-mile Lower Box and Class V+ in the 6-mile Upper Box, which is recommended for experts only. Rapids like "Boat Reamer" and "Screaming Left-Hand Turn" offer intense thrills within this deep basalt canyon.
The canyons and surrounding wilderness are home to diverse wildlife. In the Pecos Wilderness, you might spot elk, deer, bear, turkey, and Rocky Mountain Bighorn Sheep. The Rio Grande Gorge, particularly the Taos Box, offers excellent opportunities for viewing bighorn sheep, beavers, and eagles. The area around Zapata Falls is also an ideal environment for the black swift bird.
For hiking, you can explore trails like the Slide Trail, which offers stunning views above the Rio Grande, or the Big Arsenic Trail, descending to the Rio Grande with views of ancient petroglyphs. The River Trail parallels the Río Grande, connecting various trails for different loop options. For more hiking options in the wider region, check out the Hiking in the Sangre de Christo Mountains guide, which includes routes like the Borrego, Windsor, and Bear Wallow Trail Loop.
While some canyon areas are rugged, Zapata Falls offers a moderately steep, short hike that is rewarding for families. Wading through the cold waters of Zapata Creek to reach the hidden waterfall can be a unique adventure. The parking lot also provides panoramic views suitable for all ages. Always check specific trail conditions and difficulty before heading out with children.
The best time to visit depends on your activity. For hiking and enjoying wildflowers, July and August are vibrant months, especially in the high-country meadows of the Pecos Wilderness. For whitewater rafting, the spring and summer months when river levels are higher are ideal. In winter, Zapata Falls transforms into a spectacular column of ice, offering a different kind of experience, though wading through the creek is not recommended then.
Given the diverse terrain and activities, packing essentials include plenty of water and sun protection, especially for trails with little shade like The Slide Trail. For Zapata Falls, footwear like Chacos, Keens, or similar water sandals are recommended for wading through the cold creek. Layered clothing is advisable due to varying elevations and temperatures.
Yes, the Big Arsenic Trail in the Rio Grande del Norte National Monument features ancient petroglyphs carved on rocks, offering a glimpse into the region's past. The Sangre de Cristo Mountains themselves hold significant cultural history for indigenous peoples and early settlers.
Beyond hiking and whitewater rafting, the region offers a variety of outdoor sports. The Pecos Wilderness provides first-rate fishing opportunities in its numerous lakes and streams for rainbow, brown, and native Rio Grande cutthroat trout. You can also find guides for gravel biking and running trails in the Sangre de Cristo Mountains, with routes like the La Tierra Trails Loop for biking or the Frontside and Tenderfoot Loop for running.
While many trails are open to the public, specific regulations can apply, especially in protected areas like the Pecos Wilderness. It's always advisable to check with the local land management agencies (e.g., Santa Fe and Carson National Forests, Rio Grande del Norte National Monument) for any required permits or current restrictions before your visit, particularly for overnight stays or specific activities.
The Pecos Wilderness canyons are characterized by their deep, narrow formations, particularly on the western side, with impressive 100-foot-drop waterfalls and dramatic rock cliffs. They are part of a vast protected area with high-country elevations, diverse wildlife, and extensive trail systems. The area is also the sole known location for the rare Ipomopsis sancti-spiritus plant in one specific canyon.
