Los Gigantes beach, where two women were killed over a year ago by falling rocks, is due to reopen in the spring once work to make it safe is completed.
Santiago del Teide council has awarded the tender for the work, which is expected to start in early January and last two and a half months, at a cost of 600,000 euros.
The bulk of the project involves shoring up the rock face by injecting concrete and giant nails and then covering the face with steel netting to prevent dislodgements.
Improvements will me also made to the lighting and the nearby toilets.
