i want to know if there any water parks near by

here's a water park in Costa Teguise, it's not the best one in the world but it's not the worst either. It's always windy there.

As for recommendations:- Timanfaya National Park is a must. I'd also recommend the Cesar Manrique foundation, Rancho Texas, Cactus Gardens, the Caves (both sets of caves). Puerto Calero for lunch, Mirador Del Rio, El Golfo. To be honest, hire a car and see as much as you can, it's a beautiful island outside the resorts.

I agree with the Timamfaya Park, if you go on the evening trip for Dinner make sure you take your camera - when the open up the curtains during the evening you will need it - won't spoil the surprise in case you do go, but it's very good.
