The Limu Pools

Limu performs Niue's water trick at its clearest: the reef-rock pools bank freshwater seeping from the island's cap over the sea's salt, layering a shimmering lens that bands the basins in shifting blues and bends the light around swimmers - visibility running absurd, parrotfish and banded snakes' harmless cousins (the katuali stays respectful) sharing the lanes, and rock arches framing the outer pool's window to the swell. Steps and ledges serve the entries, snorkelling gear doubles the show, and tide state redraws the pools' map twice daily in the island manner.

What you actually see

• The two-tone lens - freshwater sheening over salt.
• The banded blues - basins shifting with light and tide.
• The rock arches - the outer pool's framed window.
• The absurd clarity - reef fish in lens-bent light.

When to go

May to October, the dry trades; mid-to-high tide fills the pools' best swimming - the island tide chart is the schedule.

Honest expectations

Ledges are sharp and entries rock-shod - reef shoes standard; swell days close the outer pool's argument, honestly.
