Tide pooling near Palo Alto

Twice a day the Pacific pulls back from the rocky shelves of the San Mateo coast. At the lowest tides of the month, whole reefs appear: pools full of green anemones, purple urchins, hermit crabs, sea stars and darting sculpins. Fitzgerald Marine Reserve in Moss Beach, about 40 to 50 minutes from Palo Alto, is one of the richest tide pool areas in Northern California. Pescadero, Bean Hollow and Natural Bridges in Santa Cruz add more choices.

Tide pooling is all about timing. Go at the wrong hour and you will see waves crashing over bare rock. This guide covers the best spots, how to plan around the tide during an unusual El Niño winter and the rules that keep these marine protected areas healthy.

Where to go

Fitzgerald Marine Reserve, Moss Beach

San Mateo County Parks manages Fitzgerald Marine Reserve at 200 Nevada Avenue. The county describes a rocky shore where algae, crabs, sponges, sea stars, mollusks and fish live in the intertidal zone between high and low tide. The reserve lies inside the Montara State Marine Reserve, a marine protected area under the state's Marine Life Protection Act.

The 2026 ramp closure

The ramp from the parking lot down to the tide pools was damaged and the county closed it indefinitely on August 26, 2026. Until it reopens, walk the California Coastal Trail from the reserve lot to Cypress Avenue, about 0.3 miles, turn right and take the Seal Cove stairs down to the beach. Allow extra time, especially with small children or anyone who has trouble with stairs. The stairs also make the reserve harder to reach for wheelchair users, so check the county page for updates before you go.

Hours and programs

• Opens: 8 a.m. every day, holidays included.
• Closes: 5 p.m. from November 2, 2026 through February 2027. Closing time moves later in spring and summer.
• Groups: school and community groups reserve tide pool tours through the county, which also offers a free pre-field trip program for grade school classes.
• Events: the county lists "Exploring Plankton and Friends" on Saturday, November 14, 2026.

Pescadero and Bean Hollow

South of Half Moon Bay, Highway 1 passes two state beaches with good tide pools. State Parks describes Pescadero State Beach as a long sandy beach that stretches to a rocky tidal zone ideal for tide pooling, beside Pescadero Marsh Natural Preserve, one of the best birding spots on the coast and covered in our birdwatching guide. Dogs are not allowed. The vehicle fee is $8 and when no attendant is present the self-pay envelope takes only US cash and checks.

Three miles farther south, Bean Hollow State Beach covers a mile of shoreline with two parking lots. Pebble Beach is named for its rounded, ocean-polished stones. Bean Hollow Beach is a small sandy cove flanked by rocky tide pools with anemones, crabs and sea urchins. The Arroyo de los Frijoles Trail links the two lots in one mile with interpretive panels. State Parks asks visitors only to observe, not to touch or disturb the pools. It bans collecting of any kind, including pebbles. It is the dog owner's choice on this stretch, with leashed dogs allowed on the beach.

Natural Bridges, Santa Cruz

On the west edge of Santa Cruz, Natural Bridges State Beach is known for its wave-carved sea arch, family beach, tide pools and monarch butterflies. State Parks says low tides reveal sea stars, shore crabs, sea anemones and other ocean life in this marine protected area. The park is open 8 a.m. to sunset and charges $10 per vehicle. Dogs are not allowed. From late fall into winter the monarch grove hosts thousands of butterflies, which makes November to January a good time to combine both. See our Santa Cruz day trip for the rest of town.

Planning around the tide

The coast has two high and two low tides most days and they are not equal. For tide pooling you want the lower of the two lows, ideally a negative tide, shown with a minus sign on a tide table. NOAA publishes free predictions for coastal stations such as Half Moon Bay.

1. Find a negative low on a day you are free. In winter many of the lowest daylight tides fall in the afternoon. In late spring and summer they shift to early morning.
2. Arrive an hour early. Walk out as the water drops and explore near the lowest point.
3. Turn back on time. The tide comes in faster than most people expect and can cut off ledges.
4. Check the closing time. At Fitzgerald a late afternoon low in winter can bump against the 5 p.m. closing.

The El Niño factor this winter

In October 2026 San Mateo County Parks warned that NOAA expected a strong to very strong El Niño and that the ocean was running 1 to 2 feet higher than tide tables typically show. In practice a predicted low of minus 1 foot may behave more like zero or plus 1. Pick the lowest tides you can find and keep expectations flexible. The county also forecast king tides, the highest of the year, from November 21 to 28, 2026, December 20 to 27, 2026 and January 17 to 24, 2027. Expect flooded low trails and lots near the coast on those days, along with very low tides a few hours later.

Rules and etiquette

Families with young naturalists will find more ideas in our guide to nature programs for kids. If you want to stay on the coast for an early low tide, you can compare coastside vacation rentals. Check our weather guide too, because coastal fog and wind can turn a sunny Palo Alto morning into a cold beach day.
