Corcoran Lagoon Beach in Santa Cruz is a wide and deep stretch of sand located between 20th and 23rd Avenues on East Cliff Drive. While it offers plenty of space for visitors to soak up the sun, parking can be a bit of a headache. There's no designated parking area, so watch out for those pesky weekend citations if you don't have a special permit. Just be cautious when the lagoon water flows into the ocean, as it can get a bit gnarly.
