The Muttart Conservatory is one of Edmonton's most distinctive landmarks — four glass pyramids rising from the south bank of the North Saskatchewan River, each enclosing a different biome. Three permanent pyramids contain tropical, arid, and temperate plant collections; the fourth cycles through changing seasonal and themed displays throughout the year.
The tropical pyramid is lush and humid, a genuine relief in winter — the kind of warm green air that takes half a minute to adjust to. The arid pyramid is the most dramatic, with desert landscapes from several continents and cacti that have had decades to grow. The temperate collection includes plants familiar to Albertans alongside species from similar climates worldwide. The show pyramid changes often enough that repeat visits stay interesting.
The grounds around the pyramids along the river valley are worth exploring in good weather, with views back toward the downtown skyline. Edmonton Parks runs the facility; admission is charged.
