Where are we going today?

Who's ready to make a SPLAH this summer!? If you want some good old fashioned cooling off in that Californian sun, then you might want to head to Mustang Water Park, which is great fun for ALL ages!

The water park itself is located in a campground just 10 miles east of the nearest town - Arroyo Grande. If you want a water park with a few, then just check out the amazing Lopez Lake that you will be overlooking! Far from traffic and noise - just oak studded hills!

Mustang Water Park is also filled with fun water activities, from kiddie pools and slides, so you will have a great time too!

If you are feeling a little brave, then you might want to try and take on the Awesome Stampede. It's here that you can plummet down 38 feet of a HUGE half-pipe in your own inner tube, then you speed up the other side. 

Can you guess what happens then? You only stop - then start the whole process all over again!

Then there are the water slides. Mustang Water Park has two giant 600 foot slides that curve around, taking you on a super fun trip from the hilltop that overlooks the lake, to giving you a huge SPLASH in the bottom of the pool at the bottom.

If you have little ones in the family, they can have just as much fun in the two wading pools, perfect for kids aged 9 and younger. There are also three mini-slides as well as two waterfall trees.

Parents, there is a deck for you to sun yourself on, or you can join in!

Kids - don't forget to look out for the wildlife too! If you're lucky, you might spot a deer or even a quail!

Great summer fun in California!

    I've taken my kids here several times through the years and they always loved it. The hardest part is dragging them out when it's time to go. Don't get me wrong it's no Raging Waters. But it is still fun, the prices are reasonable and the kids have a lot of fun.
