Aviara is a resort community in the hills of southern Carlsbad, overlooking the Pacific Ocean and Batiquitos Lagoon.
Carlsbad's history begins with the LuiseƱo people who located one of their villages, Palamai, near what is today Agua Hedionda Lagoon.
Carlsbad Cavern, with one of the world's largest underground chambers and countless formations, is also highly accessible, with a variety of tours offered year round.
The story of the creation of Carlsbad Cavern begins 250 million years ago with the creation of a 400 mile long reef in an inland sea that covered this region.
Some of the more unusual formations to occur in Carlsbad Cavern are helictites, which grow seemingly without regard to gravity, their twisting shapes governed by crystal shapes, impurities and the force of water under pressure.
