I think Tenerife is perfect family destination. There is so many activities.. from water parks, riding a camel, seeing dolphin shows , parasailing, trekking volcano. You definitely won’t get bored
Siam Park – water park for everybody. Trust me you will not regret.
Loro Parque – Zoo, where you can see killer whale or dolphin show (I’m not a big fan of forcing animals to perform, but I try to believe they take care of them good), apart of that you can hold a parrot or see a giant turtle.
Parasailing- Fun water/ beach activity with a best view over shore and town.
Camel ride – Tried it but I prefer camels to walk freely. I have a lot of empathy when it comes to animals. Sorry
Quad bikes/ beach buggy – if you have a bit of adrenaline in your blood and want to test your driving skills, this activity will be for you.
