What are kelp forests?

Giant kelp grows up to 175 feet tall, creating underwater forests along the California coast. These forests support over 1,000 species and produce more biomass per square meter than tropical rainforests. Kelp forests are threatened by warming oceans and sea urchin overgrazing — marine conservation areas help protect them.

Make it a road trip: Pair a visit with Hearst San Simeon State Park (a short drive away) or San Simeon State Park (a short drive away).
