Maiden Pools is one of several destinations on the Ventana Canyon Trail. See instructions and reviews for that trail. Not sure why this section is rated moderate and the longer trail hard. I’d say the lower canyon is easy (first mile or so) but as the trail ascends it gets much steeper and more rocky - i.e. hard. The trailhead is within the Ventana Canyon Resort and the first section of the trail runs along an easement through private property. It is well travelled and the trail is obvious.
