Robert H. Treman first purchased land surrounding Enfield Falls in 1915, and worked to improve the property by planting over 1,000 trees. He and his wife, Laura Treman, donated the land to New York State in 1920 for the establishment of Enfield Glen State Park. The park was renamed in Robert H. Treman's honor following his death in 1937.

The rock formations within the park are primarily made of Devonian shale and sandstone. These rocks formed in horizontal layers, creating flat slabs and angular edges as they erode and fracture.

The valley and waterfalls formed since the last ice age — within the last twenty or thirty thousands years — roughly in-line with previous streambeds. However, around Lucifer Falls, the current streambed completely deviates from its now drift-filled interglacial streambed. This path of new erosion is distinguished by its steep cliffs and narrow gorge.

The park has numerous waterfalls along a 4.5-mile round-trip hike. The hiking trails follow Enfield Creek, giving many views of the rock formations in the deep, narrow gorge known as Enfield Glen. A natural swimming pool is located at the easternmost waterfall, known as Lower Falls. Lucifer Falls, a 115-foot-tall, multi-tiered cascading waterfall, is a short hike from the western portion of the park. Views of Lucifer Falls can be found along the gorge trail, in addition to overlooks along the rim trail.
