When you're Tenerife you must visit the Monkey Zoo Park . This is a brilliant amazing attraction. I've been to Tenerife many times and never knew this park existed. Although the park is quite small It's a shame it's not advertised. It appears to be in need of funds, as everything they earn appears to go on the animals rather than the surroundings unlike other parks. Although they sell food please take along some grapes and plenty of bananas ( and a knife to slice them). It has to be the best experience ever, you can go right into the monkey enclosures and feed them. You'll be amazed, they're so tame, eat right out of your hand, and climb on to your shoulder. Also in the park are chimps, crocodiles, tortoises, black leopards, and species of different birds.
I think it's the best animal park you could visit . Just off the TF1, only 5 minutes by taxi from Los Cristianos and Las Americas. Only €10 Euros for adults (I think over 4yr olds are charged about €4) This is probably one of the cheapest attractions in Tenerife. They will call a taxi for you when you're ready to leave.
