Southwest® flights from Denver to Phoenix from $89

After you get your fill of the quirky castle, head to the Heard Museum. Founded in 1929, the museum is dedicated to advancing art and perspective of Native Americans, especially those from the Southwest. It maintains direct relationships with artists and tribal communities to provide an authentic and distinct perspective through galleries, performances, interactive exhibits, and events.

Finish your touring with a little fun at the Salt River. The river, the largest tributary of the Gila River, flows west and southwest just south of downtown Phoenix. The Salt River is your chance to experience a rarity in nature: a naturally occurring salty river. The river turns salty thanks to the presence of tamarisk trees along its banks. The trees, sometimes called Salt Cedars, draw salt from underground deposits which are then transferred to the river. Salinity aside, the river is great for tubing, rafting, and more.

These are just a few of the hundreds of things the Phoenix area has to offer. Explore more for yourself and book your trip now.
