Although there is a Jewish population in Spain of just under 50,000 people, Jewish communities tend to be centred round areas other than the Canary Islands.
The two major centres of Jewish life are Madrid and Barcelona, both with around 3,500 Jews. Closely following are the centres of Malaga, Alicante, Benidorm, Cadiz, Granada, Marbella, Torremolinos and Valencia.
As you'd expect, some of these places will have a synagogue. Unfortunately for Jewish people visiting (or living in) Tenerife, the island doesn't appear to have one (although, see below).
Several Jewish websites, however, tell of a synagogue on the Canary Island of La Palma. Try as I might, I can't discover its location.
There is a non-jewish website I've come across that claims that there is a synagogue in Santa Cruz, Tenerife, on "Calle Bethencourt". The only street with a name approaching that is Calle Bethencourt y Molina, found just off the major road, Avenida Tres de Mayo. Believe it or not, I've undertaken a virtual journey up and down that street, using Google street view and I couldn't see any building resembling a synagogue. I think it's best if you take that assertion with a pinch of salt.
If anybody knows different and has the actual location of such a building, please let me know, via feedback.
Anyway, back to the one on La Palma, which, since it is mentioned by more than one Jewish website, is more likely to be accurate. There are three ferry companies connecting the different Canary Islands and it's possible to sail from Tenerife to La Palma with all three. The journey can take up to 2 and a half hours. Details of these companies can be found here.

Jewish Holidays in Tenerife
There is a company called Klub Premiere that operates kosher holidays to Tenerife. With accommodation at the luxurious Hotel Botanico, it is under the strict control of the Beth-Din of Nice. Last year, the dates were 4th-25th of August. The company has yet to announce any dates for this year, but you can visit their website here.
Kosher Restaurants
At the time of writing, I've not managed to unearth any kosher restaurants in Tenerife - but I bet there are some! If any come to light in the future, I'll insert them here.
