The guide leads from a dusty hotel courtyard before the land opens into a narrow canyon; stone walls lean in close and the Rio Grande dares you forward, its shallow channels glinting in the sun. Footfalls on gravel shift the silence and, step by deliberate step, the landscape peels away into wide salt flats and towering cliffs marked with ancient marks.

Carry 2–3 liters of water
There is little shade and high UV; hydrate before and during the trek to avoid heat exhaustion.
Wear sturdy, grippy hiking boots
Loose riverbed gravel and short steep sections demand stable footwear with ankle support.
Start early in the morning
Temperatures climb quickly—begin before 8 AM to avoid mid-day heat and get better light on petroglyphs.
Respect the rock art
Do not touch or climb on petroglyph panels; natural oils and abrasion damage ancient engravings.
Water bottles or hydration bladder (2–3 L)
Hydration is critical in the high desert; carry at least 2 liters for shorter routes and closer to 3 for the 16 km option.
Sturdy hiking boots
Support and traction help on loose gravel, riverbed sand and brief scrambling sections.
Sun protection (hat, sunglasses, SPF 50+)
High UV and reflected light from salt flats make strong sun protection necessary year-round, especially in summer.
