Yosemite Firefall — Horsetail Fall

For about ten minutes on the right February evening, the last light of sunset hits Horsetail Fall at exactly the angle that turns the thin ribbon of water down El Capitan's east face into what looks unmistakably like flowing lava — no filters, no trick, just geometry and water doing something that reads as fire. It's called Firefall, and it only works during a narrow window in mid-to-late February, and only some of those evenings.

Three things have to align, and only one of them is guaranteed. The sun angle is fixed and predictable — that's the February window itself, no uncertainty there. Clear sky at sunset toward the west is a coin flip; a marine layer or storm front kills the glow entirely. And there has to be water actually flowing in the fall, which depends on snowpack — a dry winter can leave Horsetail bone-dry with the light perfectly positioned and nothing to catch it. All three conditions, same evening, or you get a very nice sunset and nothing more.

Yosemite dropped its multi-year Firefall reservation system in January 2026 and confirmed no timed entry for the year — but that policy is reset annually each January, and Feb 2027's rules aren't announced yet; viral crowding could bring reservations back before your trip. Standard park entry applies ($35/vehicle, cashless, plus a $100/person surcharge for non-US residents 16+). Build in multiple evenings if you can — this is one of the most weather-gated phenomena on the board, and a single-shot trip is a real gamble.
