The Green Planet is a climate-controlled biodome in City Walk, housing a four-storey indoor tropical rainforest ecosystem with over 3,000 plants and 500 animals. At its centre is a 25-metre artificial tree that forms the structural spine of the ecosystem and houses nocturnal species on its upper levels, accessible by walkways that spiral around the trunk.
The biodome is one of the more unusual attractions in the city. The animals — sloths, pythons, toucans, meerkats, and dozens of bird and reptile species — live in genuinely immersive environments rather than conventional cages. It is well suited to children but interesting for anyone with a curiosity about tropical ecosystems. The humidity inside (around 70–80%) is a shock after the air-conditioned desert of everywhere else in Dubai.
