5 patches across 4 counties, 1 free to enter. The season opens September 18 at Chatfield Farm (Denver Botanic Gardens).
5 of the 16 Colorado patches we track are in Denver Metro, spread across Adams County, Arapahoe County, Jefferson County, Weld County. 5 of them run a corn or crop maze, and 2 have farm animals your kids can get close to. 3 have their 2026 dates confirmed on the farm's own site.
One patch here is free to walk into, which makes it the low-risk option with unpredictable toddlers — you are not out $80 if the visit lasts twenty minutes.
