Hiking around El Rosario
A breathtakingly beautiful and magnificent hike to the Argua Garchia caves. It had rained three days before our hike, and we had to be very careful not to slip. Despite this, it was a fantastic hike to the caves that we won't forget. The caves were created to extract sand from the mountains for glassmaking. Unfortunately, the profits weren't sufficient, and the Spanish ceased production. This happened many years ago, and the local poor then used the caves as living quarters. Hardly imaginable by today's standards. A visit is highly recommended and fascinating 👍🏻.

A fantastic hiking trail leads along here, amidst beautiful nature 💚 highly recommended. The bridge is very sturdy and leads to the glass caves, which are stunning and definitely worth a visit 👍🏻. I wonder what kind of hard work it must have been to create these tunnels and then extract sand to produce glass. Unfortunately, it didn't bring the Spanish the desired success, so the project was abandoned. The poor local population then used the caves as shelter. Unthinkable in this day and age.

The Red Cave is a historic enclave. A section of the famous "Camino de Las Lecheras" passes through here. This route was used by the old dairy farms of La Laguna to transport their goods and exchange food in Santa Cruz de Tenerife. The road began at the Cruz de los Álamos in Las Mercedes and ended at the Recova Vieja, next to the current site of the Guimerá Theater in Santa Cruz de Tenerife.

There are two such "caves" on the route. They are obviously lava tubes, although one of them has been worked by human hands to a certain depth.
