In short: in heron pose you sit with one leg folded back beside the hip, as in hero pose, and lift the other leg straight up in front of you, holding the foot with both hands and drawing the leg and the chest toward each other. The lifted leg looks like a heron’s long neck. It is an intense hamstring stretch that asks for a long, upright spine. A strap around the foot makes it accessible long before the leg will straighten fully.
Heron pose is part of the Ashtanga intermediate series and appears in Yoga Journal’s pose library for general hatha practice. Below are the name, the cues behind the steps, the knee precautions and where heron fits in a practice.
What the name means
The Sanskrit name is Krauñcāsana, also written Krounchasana or Kraunchasana. Krauñca is a long-legged bird: Yoga Journal translates it as crane, heron or other long-legged water bird, and AshtangaYoga.info as curlew. Yoga Journal also notes that Vyasa, the oldest surviving commentator on the Yoga Sutras, mentions a curlew seat in his comment on sutra 2.46, without describing how to do it, so we cannot say whether that seat was this shape. The pose as taught today is described by the 20th-century Mysore lineages.
Making heron pose work
The lifted leg is the goal, but the back is the priority. Lean back slightly, keep the front of the torso long and firm the shoulder blades so the chest stays lifted. If the chest collapses as you lift the leg, loop a strap around the sole and hold it close to the foot with straight elbows; Yoga Journal recommends exactly this for most beginners. Raise the leg diagonally, at about 45 degrees, or higher only as long as the spine stays long. When you can hold the foot with straight arms, bend the elbows outward and draw the leg and torso together; in Ashtanga the chin moves toward the shin and the gaze goes to the pointed foot.
The folded leg needs care. If the knee or ankle complains in the hero-pose position, keep that leg straight on the floor instead, or bend it out to the side as in head-to-knee pose. Hold for 30 seconds to a minute (Yoga Journal) or five breaths (Ashtanga), then change sides.
Precautions in plain words
Yoga Journal advises people with serious knee or ankle problems to avoid the half-hero leg position unless an experienced teacher is helping, and to use the head-to-knee leg position instead. Hamstring injuries call for the strap version with the leg low. With lower-back problems, keep the leg low and the spine upright. This page is general information, not individual advice.
Preparation and what comes next
Regular hero pose prepares the folded leg. Reclining hand-to-big-toe pose stretches the same hamstring with the back supported, and seated forward bend and three-limbed forward bend, which uses the same folded leg, are good preparation too. A gentle twist or staff pose settles the legs afterwards.
A simple way to practise it. Start with the strap and the bottom leg straight, sitting on a folded blanket, and lift the leg only until you feel the hamstring stretch while the chest stays lifted. Hold for several breaths, lower the leg, and repeat once. Over time, walk the hands up the strap toward the foot. Yoga Journal also describes a partner version in which a helper gently supports the heel while you keep the torso upright; the helper should stop as soon as you feel a comfortable stretch.
You will meet heron pose in Ashtanga (intermediate series) and in some hatha classes.
