La Espasa is essentially just a beach with a couple of restaurants along the promenade, as well as a public restroom and a kids park (in case you were looking for a flying fox).
The town of La Isla sits to the north of the N-632, and the camino does not technically pass through town. From the albergue in La Isla it is possible to get to Colunga via a coastal path that takes you through Güerres. Inquire at the albergue for more information.
The camino follows the beach here, at the far end of which is a bar and public restroom. Beyond that the camino crosses a small river and follows along the N-632.
At this point the camino follows along the N-632, leaving it on several occasions for safety but always returning to it.
