Hexagon pool, Artificial pond at Meshushim Stream Nature Reserve, Golan Heights, Israel.

The Hexagon Pool is a natural pool at the foot of a canyon in the Meshushim River, within the Yehudiya Forest Nature Reserve. Its walls are made of basalt columns about 5 metres high, mostly five- or six-sided and 30 to 40 centimetres in diameter, formed by cooling lava. A small waterfall feeds the pool, which reaches a depth of 6 to 7 metres.

The basalt columns formed millions of years ago when lava flows cooled and contracted, causing them to crack into regular polygonal shapes. This natural cooling process created the distinctive pattern visible in the stone today.

The name Breichat HaMeshushim refers to the hexagonal (meshushim) cross-section of the basalt columns, which look as if they were cut by hand. The pool lies in the Meshushim River within the Yehudiya Forest Nature Reserve, and the Stream Trail passes an old olive grove from the Syrian administration era.

The pool is reached by walking downhill on a trail that takes about 30 minutes from the parking area at the reserve entrance. The water stays cold year-round, so bring appropriate swimming gear and sturdy footwear for the slippery basalt surfaces.

The pool reaches a depth of about 6 to 7 metres. Besides the dominant five- and six-sided columns, four- and seven-sided polygons can be found in the canyon walls, and the same basalt columns occur along the nearby Zavitan River.
