I've had a look on the TITSA website and it appears that bus number 910 will take you from Santa Cruz to Las Teresitas beach. Its frequency is about every 20 mins. To have a look at the appropriate page on their site yourself, click here.
Hope you enjoy your visit!

Bus to La Teresitas Beach by: Mrs Emery
Thank you John for getting back to me so quickly. This is the very first time I have done this sort of thing! And it is quite amazing to receive the information from someone you don't know, and with all the knowledge you have it is marvellous. It is the best thing I ever did buying a computer, I now can go around the world!! Thanks John for your help. Mrs Emery

La Teresitas Beach by: Mrs Emery
Hi John, We are now back from our cruise. When we docked at Santa Cruz - Tenerife, we took the 910 bus to Teresitas beach, took about 15mins, wonderful beach, spent all aftenoon there. Took a bus back to the ship and got ready for dinner. Thanks for the bus information, much appreciated. More people should try it. Thanks. Mrs Emery.
