The season
What fills Zapata Falls, and when
South Zapata Creek carries Sangre de Cristo snowmelt, and the BLM's own page draws the seasonal contrast: a cooling oasis in summer, an enormous frozen column for experienced ice climbers in winter. The biggest water pushes through the crevice from May to mid July, which is also when the required creek ford is coldest and swiftest.

What the agency itself says
During the summer months, the falls provide a cooling oasis, but during the winter months, the waterfall freezes into an enormous column of ice, perfect for the experienced ice climber.

Getting there
Access, in the agency's words and ours
The BLM describes a mildly steep half mile hike, after which viewing the falls requires fording the stream and climbing rocks inside the crevice. Day use is free; a 24 site campground above the trailhead overlooks the San Luis Valley. Black swifts nest at the falls, one of few known Colorado breeding sites, per the BLM.
