Solana Beach is one of the seaside communities of San Diego County in Southern California. It is situated a bit less than 40 km (around 22 mi.) north of downtown San Siego, between Del Mar and Cardiff-by-the-Sea. Seen here in this drone video by ayman803, Solana Beach has seen thousands of residential units built atop its sandstone bluffs. Many of these were built during decades of cooperative weather; unfortunately, in recent years, some of these bluffs have collapsed during periods of heavy rainfall.
