The rocky shore below Puerto del Carmen's old-town promenade, where unraked rocks keep lilac and aqua sea glass.
Las Canteras is the long city beach of Las Palmas. At low tide pebbly patches appear on its southern stretch, between Peña la Vieja and La Cícer, and that is where the glass collects.
Loads of glass in a wide range, including aqua, lavender, teal, cobalt, red and orange.
