Pedra de Lume salt pools
Salt pans inside an extinct volcanic crater, reached through a tunnel in the crater wall, where the brine is so dense you float without trying. Avoid shaving beforehand, keep the water out of your eyes, and use the showers afterwards.
Buracona and the Blue Eye
A natural rock pool on Sal's rugged north-west coast, beside a cave where sunlight turns the water electric blue. The effect is strongest around midday in sunshine, and waves can wash over the rocks, so stay back when the sea is up.
Shark Bay
Young lemon sharks, harmless to people, gather in the shallows of this bay on Sal's east coast, and you can wade out knee-deep to watch them glide past. Wear water shoes, keep still and never touch them.
Turtle nesting walks
From about July to October loggerhead turtles come ashore on Sal and Boa Vista to lay their eggs, and the hatchlings follow later in the season. Join a licensed guided walk, because torches, flash photography and wandering the beaches at night disturb them.
Whale watching from Sal Rei
Humpback whales come to breed off Boa Vista from about March to May, and boats leave Sal Rei harbour in the mornings, when the sea is calmer. Sightings are likely rather than guaranteed, and the swell can be lively, so take seasickness tablets.
Kitesurfing lessons
Santa Maria's Kite Beach and Sal Rei have schools for every level, and the steady winter wind makes learning quicker than on gustier coasts. Book a block of lessons early in the holiday, in case a calm day intervenes.
Viana Desert
A sea of pale dunes in the middle of Boa Vista, crossed on quad and 4x4 trips that often carry on to the rusting wreck of the Cabo Santa Maria on the north coast. Go early or late, when the sand is cooler and the light softer.
Live music in Mindelo
Evenings of morna and coladeira in the bars and restaurants of Mindelo, the home town of the singer Cesária Évora. Music starts late and runs on, especially at weekends.
Walking on Santo Antão
A ferry from Mindelo crosses to Santo Antão, whose green valleys, terraced fields and cobbled cliff-edge roads are the walking highlight of the islands. The crossing can be rough, and two nights let you walk a valley such as Paul without watching the clock.
Santa Maria fishing pier
Towards lunchtime the boats come in and tuna and wahoo are cleaned and sold on the jetty. It is the liveliest scene in town, and the light is best for photographs in the late morning.
