US-04 Grand Canyon Pop

---

Grand Canyon Rim‑to‑Rim is a full crossing of one of the most iconic landscapes on Earth — a descent through a billion years of geologic time, a traverse of desert worlds, and a climb back into the sky. Starting on the cool, forested North Rim and finishing on the South Rim, this single‑day epic delivers heat, scale, river roar, and a sense of journey unlike anything else in the Blisterpop canon. It’s a mythic passage through deep time and canyon country — a true desert endurance classic.

• Base Town: Grand Canyon South Rim, Arizona

• Distance: 24 miles

• Elevation Gain: 5,278 ft

• Estimated Time: 12–18 hours

• Route Type: Point-to-Point

The best seasons for a Rim‑to‑Rim crossing are May–June and September–October, when temperatures on the canyon floor are survivable and water sources are reliably flowing. Summer attempts are extremely dangerous — the inner canyon regularly exceeds 100–110°F. Early starts are essential in every season, and the North Rim typically opens in mid‑May, making fall and late spring the prime windows for a safe, powerful crossing.
