Golden Hinde is a saltwater beach in Marin County, California. Across 185 bacteria samples collected between 2021 and 2025 at nearby monitoring stations, it earns a Beach Safety Grade of D — Poor.
About 23% of samples at Golden Hinde exceeded the EPA Beach Action Value of 235 CFU/100 mL for Escherichia coli — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was frequently crossed here over the monitored period. Bacteria samples frequently exceed the safe-swimming threshold; swimming advisories are common here.
The evidence behind this grade is deep for a beach page: 185 results from 2 monitoring stations, spanning 2021 to 2025. Enough sampling, from enough places, over enough seasons that one bad week can't drive the letter.
Golden Hinde is currently listed as inactive in the EPA beach-monitoring program, so it may no longer be routinely sampled. Its grade reflects the water-quality results collected while it was active — useful history, but confirm the beach's current status and any local advisory before you visit.
