Hylocereus trigonus grows liana-like, climbing and spreading and reaches a length of up to 10 meters. The green, slender, triangular shoots are strongly wavy on the back of the ribs and not horny. From the areoles located on the upper tip of the curved notches arise from 1 to 14 stiff and differently shaped spines . They are 4 to 7 millimeters long and turn brownish over time. Sometimes the areoles are still covered with a few bristles.

The white flowers are 14 to 25 inches long. The scales on the pericarpel do not overlap. The elongated, red fruits are 3 to 5 centimeters in diameter and up to 10 centimeters long. The fruits are covered with fleshy scales.
