Corona del Mar Tide Pools and Tide Chart

Unlike a park with a gate, Little Corona has no tide pool hours of its own, so this table has no hours column. The city opens all its ocean and bay beaches from 6 a.m. to 10 p.m., and almost every daylight low falls inside that. Over the 12 months from October 2026, our count found only two windows outside it, both very good lows just before 6 a.m. in June and July. If one of those dawn lows is on your list, wait for the 6 a.m. opening; the water will still be near its lowest for a while after.

How low is low enough here? The ratings follow the site’s rule, the same one used for every beach, so a very good day at Little Corona is a low tide at or below 0.0 ft in daylight. The lower the tide, the more of the rocks come out of the water, so the very good days show the most; good days, up to 1.0 ft, still uncover pools, just fewer of them.

The city’s directions start on Marguerite Avenue: turn toward the ocean on Marguerite, then left on Ocean Avenue, and the entrance to the refuge is at the corner with Poppy Avenue. From there a path leads down to the beach. There is no lot for Little Corona itself. Parking is on the residential streets around that corner, and the city warns that it regularly tickets cars left where the “No Parking” signs say not to.

The beach between Little Corona and the harbor entrance is Corona del Mar State Beach. It has what Little Corona lacks: fire rings, public barbecues used on a first-come basis, and one beach wheelchair, which cannot be reserved. Portable grills are not allowed on any city beach. The state beach borders the northern end of the Crystal Cove State Marine Conservation Area, the protected stretch of coast that runs southeast from here.

A 2014 report in the Newport Beach Independent on the Little Corona tidepools gave a long list of what visitors find in them. Gooseneck barnacles and mussels crowd the rock faces; turban snails, kelp snails and rough limpets graze on them; hermit crabs, shore crabs and rock lice move between the cracks. In the pools themselves are sea anemones, sponges, sea stars and small fish such as sculpin and opaleye, with an octopus now and then. The deeper the low tide, the more of the outer rocks, and the life on them, comes into view.

The city’s rule is short: nothing may be removed from a tidepool, not even for a moment, on any beach from Corona del Mar State Beach south. That covers Little Corona. Its own advice is to take only memories, and it points out that a shell which looks empty is often a home waiting for its next tenant, so leave those too.

State law adds weight to it. In the Crystal Cove State Marine Conservation Area, which begins beside Corona del Mar State Beach, taking any living marine resource from inside a tidepool is prohibited, and the regulation defines a tidepool as a rocky pool filled by the retreating tide, anywhere between the high and low water lines. Look, photograph, and put back any rock you lift exactly as it was.

The usual city beach rules apply at Little Corona as well: no glass and no alcohol on the sand, and no dogs on the beach or the beachfront sidewalk between 10 a.m. and 4:30 p.m. Outside those hours a dog may come along on a leash.

For Little Corona this list matters most in summer, when the daylight lows come early in the morning and some of them arrive before city beaches open at 6 a.m. In fall and winter the same lows move into the afternoon. Anyone bringing a dog should note the other clock on city beaches: dogs are allowed only before 10 a.m. and after 4:30 p.m., on a leash, so a midday low means leaving the dog at home.

This station is shared: the Newport Beach tide chart uses it too, so the two pages always show the same tide times and heights. The site normally gives each page a station of its own, but every other usable station within 30 km already serves another beach, and the nearest unshared one is 40 km away, behind the San Pedro breakwater. NOAA’s own name for this station includes Corona del Mar, and it stands on the jetty at the harbor entrance, at the west end of Corona del Mar State Beach. Before settling on the shared station, the site checked that unshared one too. Over 30 days its tide pool windows matched this station’s exactly, and over 12 months they differed on only four days, all with lows close to the 1.0 ft line. Sharing the nearer station costs nothing in accuracy and keeps the station line honest about distance. What this page adds is the tide pool view of those numbers for Little Corona.
