I visited this "Centro de Interpretacion" on November 8th, 2019: I had planned to stay over there 20 minutes and ended by remaining for more than 2 hours. The display is great with much information about the shaping of the social and natural environment of El Hierro across time. The exhibit - in Spanish and English - also includes small videos and gives insight over several unusual aspects of El Hierro, e.g. the way how the populace had fun and danced in the past, when El Hierro was one of the most isolated places in Spain. A special note of thanks to the staff - in particular to Mr. Luis - who during my visit took the time to delve into and explain in depth the meaning of many items on display and added even more information: he is a very knowledgeable and kind person, passionate about his role, about the "Centro de Interpretacion" where he works and more in general about El Hierro. I highly recommend everyone in El Hierro to find the time to visit the "Centro de Interpretacion de la Reserva de La Biosfera" in Isora (open Tuesdays-Sundays 10.00 am-06.00 pm; closed on Mondays), which may be coupled with a visit to El Mirador De Isora, with spectacular views on Las Playas cliffs.

This was a really interesting place, full of information about the island's geography, history and culture. It was only a few euros entrance and took less than an hour. Worth a visit if you want to understand more about El Hierro.
