An unforgettable experience awaits you in the Elkhorn Slough National Estuarine Reserve – a very special place unlike any other. The remainder of an ancient river valley, it is the United States' first estuarine sanctuary and California's second largest estuary.
Elkhorn Slough is a 6-mile-long tidal ‘slough’ (a tidal channel in a wetland) and ‘estuary’ (a partially enclosed coastal body of water with one or more rivers or streams flowing into it) on Monterey Bay in Monterey County, California. Just a 20-minute drive south from Santa Cruz and a 20-minute drive north from Monterey, California.
Sea Otters, Harbor Seals and Sea Lions are guaranteed to be seen as you Hydrobike quietly through its waters. The Slough is home to more than 340 different bird species and the largest Sea Otter population in all of California.
