Tucson's desert cascade: seven pools stacked in Bear Canyon, flowing after winter rains and monsoon bursts, dry-ish in between, and reached across numerous stream crossings.

The season
What fills Seven Falls, and when
Bear Creek is a Sonoran Desert stream, and the Forest Service's trail description carries the operative phrase: when the water is running, your feet will get wet. Winter rains from February to mid April are the reliable window, with the summer monsoon adding violent, brief encores. Between weather systems the falls can shrink to standing pools. Our rain-fed label reflects that regime; no gauge sits on Bear Creek itself, so let recent Tucson weather be your forecast.

What the agency itself says
The Seven Falls trail is a subsection of Bear Canyon #29. This popular trail is out and back across numerous streams and rugged terrain. Without using the shuttle service, the hike is approximately 8.5 miles round trip from the Sabino Canyon Visitor Center.
Rain-fed falls carry the color of their watershed: Blackwater Falls runs amber with tannin from spruce and hemlock bogs upstream, and its volume tracks the last month of Appalachian weather. “Blackwater Falls (15437499241)” by Benjamin Smith from United States, CC BY 2.0
Getting there
Access, in the agency's words and ours

Desert water where you least expect it (Havasu Falls, Arizona). Seven Falls is the opposite kind of desert falls: no aquifer behind it, so the rain calendar is everything. “Havasu falls Arizona” — Stolz Gary M, U.S. Fish and Wildlife Service — Public domain

Seven Falls flow season FAQ
The reliable big-water window is February through mid April. Bear Creek is a Sonoran Desert stream, and the Forest Service's trail description carries the operative phrase: when the water is running, your feet will get wet.

Bear Creek has no USGS gauge near the falls, so the seasonal pattern above is the flow guide for Seven Falls, and Coronado National Forest (US Forest Service) is the source for current conditions on the ground.
Yes, regularly; that is desert hydrology, not a malfunction. After a dry spell the seven pools shrink and the falls can stop. Go inside a couple of weeks of real rain, and mind that the same storms that fill it can flood the crossings.

Yosemite Falls in May, running on snowmelt that will be gone by late summer. The National Park Service tells visitors the falls can be dry by August, which is why every falls page here starts from its watershed. “Tourists below Yosemite Falls (39832011431)” by Mike McBey, CC BY 2.0
The blue green icon of Havasu Canyon on sovereign Havasupai land: aquifer-fed water over travertine, reachable only with a tribal permit and an eight mile hike past Supai.
A travertine falls on a creek that got its river back: 30 million gallons a day of 70 degree spring water, restored when the century-old hydro diversion was retired.
