GRAND CANYON, ARIZONA
Elves Chasm: A Hidden Grand Canyon Oasis
At mile 117.3 on the Colorado River, a narrow crack in the canyon wall hides one of the Grand Canyon's greatest surprises. From the raft, Elves Chasm barely announces itself. A small break in the Tapeats Sandstone. A few boulders at the water's edge. The sound of water somewhere beyond sight.
As you climb, the Canyon changes, and you discover a completely different world. Waterfalls tumble through a lush grotto draped in maidenhair ferns. Clear water spills over travertine ledges into deep emerald pools. The air cools instantly. Emerging into Elves Chasm feels like beholding a mirage, a tropical oasis hidden deep within the Grand Canyon.
Why Most People Never See Elves Chasm
Most Grand Canyon visitors will never see Elves Chasm. From the rim, reaching it requires one of the canyon’s longest, most demanding backpacking routes. From the river, it is a short scramble from the raft. It's close enough to feel almost secret, but hidden enough that you'd completely miss it if you didn't know it was there. Surrounded by waterfalls, ferns, and towering canyon walls, Elves Chasm feels less like the Grand Canyon and more like a hidden world tucked inside it.
River Access Changes Everything
Elves Chasm sits deep inside the Grand Canyon, far from roads, viewpoints, and maintained trails. Backpackers reach it as part of the Royal Arch Loop, a challenging multi-day route that requires route-finding, scrambling, and technical sections through rugged canyon terrain.
River runners arrive differently. On
6-Day or
7-Day trips the raft pulls to shore, and a short scramble through the Tapeats Sandstone leads directly into one of the canyon's most surprising oases. That's one of the unique advantages of seeing the Grand Canyon from the Colorado River. Places that require days of effort from the rim become part of the journey.

How Elves Chasm Came to Be
The walls of Elves Chasm are Tapeats Sandstone, a layer of rock more than 525 million years old. Long before the Grand Canyon existed, this area sat beneath a shallow sea that spread across much of North America. Today, the Tapeats forms the lower walls of many side canyons along the Colorado River.
But the most interesting rock in Elves Chasm didn't come from those cliffs.
Look around the grotto, and you'll see pale, rounded boulders wedged throughout the canyon. These are travertine, calcium carbonate deposited by the water itself. As Royal Arch Creek flows from the South Rim toward the Colorado River, it dissolves minerals from limestone layers high above. When the water reaches the chasm, those minerals begin to precipitate out, slowly building the travertine ledges, boulders, and waterfalls that define the grotto today.
In a sense, Royal Arch Creek created both halves of Elves Chasm. Over millions of years, it carved the narrow slot through solid Tapeats Sandstone. At the same time, it gradually filled portions of that slot with travertine formed from minerals carried in the water.
The waterfall at the heart of Elves Chasm is where those two stories meet. Water drops through a gap in the travertine into the pool below while maidenhair ferns, monkeyflower, and other moisture-loving plants cling to the constantly wet walls. The result is one of the most distinctive oasis environments anywhere in the Grand Canyon.
As for the name, nobody knows exactly who first called it Elves Chasm. But standing beneath the waterfalls, surrounded by ferns and green light reflected off wet stone, the name feels less like a mystery and more like an observation.
Elves Chasm: Frequently Asked Questions
Where is Elves Chasm in the Grand Canyon?
Elves Chasm is at mile 117.3 on the Colorado River, on the upper canyon section between Phantom Ranch and Havasu Creek. The chasm itself is a narrow side-canyon grotto, cut by Royal Arch Creek, which drains the South Rim country above and empties into the Colorado right at the landing. The grotto is invisible from the main river. You only see it once you step off the raft and scramble your way up to it. Just downstream, the Colorado opens into Conquistador Aisle, one of the widest and calmest stretches in the upper canyon.
How do you get to Elves Chasm?
For most people, the river is the only practical way in. A guided rafting trip noses against the landing, and from there it is a short, rocky scramble of about ten minutes up through the slot into the grotto. No climbing skill is required. The alternative is the Royal Arch Loop, a 35-mile backpacking route off the South Rim that includes rappels and serious route-finding, and is one of the most demanding multi-day hikes in the Grand Canyon backcountry. On a Western River 6-Day or 7-Day Grand Canyon Rafting Trip, the stop is built into the itinerary, if conditions allow.
Can you swim at Elves Chasm?
Yes. Swimming at Elves Chasm is one of the reasons the stop exists. The pool at the base of the grotto is cold, clear, and often deep enough to jump into at the guide's discretion. The water can be colder than the Colorado itself because Royal Arch Creek is spring-fed, and the reset after a hot canyon day is part of what makes the stop memorable.
How was Elves Chasm formed?
Elves Chasm is a side-canyon grotto cut into 525-million-year-old Tapeats Sandstone by Royal Arch Creek. What makes it unusual is what happened inside the slot after the water carved it. Royal Arch Creek drains South Rim limestone country and carries dissolved calcium. Where the water slows and splashes inside the grotto, it precipitates that calcium out as travertine. The travertine boulders and chokestones wedged in between the Tapeats walls are the result. The waterfall itself drops roughly 12 feet into the pool at the grotto's floor, and above it, additional tiers climb the chasm for a total of about 30 feet of falling water.
Which Western River trips include Elves Chasm?
Elves Chasm is a popular (but not guaranteed) stop on Western River Expeditions' 6-Day and 7-Day Grand Canyon rafting trips. Both launch at Lees Ferry and run the full upper two-thirds of the canyon. The 3-Day and 4-Day River & Ranch trips launch at Whitmore Helipad (mile 188), which is more than 70 miles downstream of Elves Chasm. Those trips do not reach the Elves.
How long do you spend at Elves Chasm?
An Elves Chasm stop is usually 45 minutes to an hour on shore, from the moment the raft ties off to the moment you are back on it. Some of that is the short scramble in and out. The rest is the pool: jumping, swimming, photographing the ferns, catching your breath in the shade. Guides set the pace based on conditions, group energy, and the overall itinerary for the day.
