A remarkable number of the archeological sites on La Palma line up with astronomical calendar events: particularly sunrise or sunset at the solstice or equinox, and the rising and setting of the star Canopus. Since Sunday was the equinox, I went with a group of friends to one of these sites to see the sun rise behind the highest point of the island, the Roque de Los Muchachos. It meant an early start, but it was well worth it.
