Jardines de Atlantico
Perhaps more suited for a visit on a cloudy day are the Jardines de Atlantico situated just outside Los Cristianos. They are open daily from around 10:00 and offer a free bus from the resorts of Los Cristianos and Playa de las Americas for the short trip to the nearby village of Buzanada. Your trip around includes commentary by an English speaking guide and lasts around an hour. In amongst the banana plantations they have a model of Tenerife that explains the water system. At the end of your visit they have a small shop selling banana related products and a cafe.
Bob Diving
Bob diving is a type of underwater scooter. Whilst they claim "everybody can do it", you will need to be over 5ft tall, aged 12+, be able to swim and put you head underwater to get into the scooter. The trip runs out of Puerto Colon harbour and lasts around 2 hours in total, during this time you will be underwater for about 30 - 40 minutes.
The cost per person is 42 Euro, which works out at a little over £28.
Camel Park
Open daily from around 10:00 to 17:00 with a free bus services from both Los Cristianos and Playa de las Americas. Not perhaps so suitable for the infirm or those that easily suffer from sea sickness. The ride lasts for about 1 hour around the fields that surround the farm. The camel park has a small cafe selling the usual range of snacks and drinks.
Places to Visit in Tenerife
These are a few of the islands other attractions that may be worth a visit:

Loro Parque
Loro Parque is Tenerife's most popular wildlife centre and receives more than 1.3 million visitors each year. Situated at outskirts of the northern resort of Puerto da la Cruz it is home to the largest parrot collection in the world and the biggest dolphinarium in Europe. If parrots are not your thing, you'll also find gorillas, jaguars and some huge tigers. The latest addition to the park, opened in the summer of 1999 is the penguin island. Throughout the day visitors are entertained with parrot, dolphin and sea lion shows, which at peak times can become very crowded. So, arrive early to get the best pool side seats. Perhaps the most impressive feature of the park is the aquarium which houses over 20,000 marine animals including some enormous sharks which are viewed through a sub-aquatic Plexiglas tunnel. The park has a large number of pizzeria, restaurants and shops and is open every day of the year. Loro Parque is open daily from 08:30 to 17:00, and for those on holiday in Puerto de la Cruz a free "road train" operates every 20 minutes
from the Playa Martinez in the centre of the resort.
