What Twin Lakes State Beach offers anglers
Twin Lakes State Beach sits at the mouth of the Pajaro River where it meets Monterey Bay, about 30 miles south of Santa Cruz. The beach itself is narrow and rocky in places, sandy in others, and the real fishing happens in the shallow bay waters and the river mouth during specific seasons. You can fish from shore without a boat, and the species change with the water temperature and time of year — striped bass and leopard sharks in cooler months, halibut and corbina when the water warms.
Access is straightforward: there is a parking lot, a day-use fee (currently around $10 per vehicle, though this varies), and no reservation needed. The beach faces south into the bay, so it is more protected than the open ocean beaches to the north. Low tide exposes more rocky structure, which holds fish but also makes wading tricky. High tide pushes water closer to shore and can improve fishing, especially near the river mouth on the western end of the beach.
Key Takeaways
- Twin Lakes State Beach is a day-use-only facility with a parking fee; bring cash or check the California State Parks website for current payment methods.
- Striped bass and leopard sharks dominate fall and winter; halibut and corbina move in during late spring and summer when water temperatures climb.
- The Pajaro River mouth (western end) holds fish year-round but can be murky after rain; the open bay side fishes better on clear days with moderate swell.
- Low tide exposes rocks and structure but makes wading hazardous; fish the last two hours of incoming tide for the best combination of access and feeding activity.
- No boats are allowed, so you are limited to shore fishing; a 7- to 8-foot medium-action rod handles the rocky terrain and the mix of species here.
Seasonal patterns and what to target
Fall and early winter (September through December) bring striped bass to the shallows as water cools. They hunt baitfish near the river mouth and along the rocky points on the bay side. Live anchovies or live mullet work best; if you cannot get live bait, white swimbaits or topwater plugs draw strikes. Leopard sharks are also active in this window and will take live bait or fresh mackerel. Both species tolerate the cooler water and the occasional freshwater pulse from the Pajaro.
Late spring through early fall (May through September) shifts the focus to halibut and corbina. Halibut prefer the sandy flats on the bay side and will eat live anchovies, small swimbaits, or soft plastics worked slowly along the bottom. Corbina are shallower, often in water less than 4 feet deep, and respond to small crustaceans, sand crabs, or tiny swimbaits. Both species are sensitive to water clarity; fish the incoming tide when the water is clearest, usually early morning or late afternoon.
Winter storms (December through February) can muddy the river mouth and make the bay side your better bet. Striped bass and leopard sharks are still present but may move to clearer water. If the Pajaro is running high and brown, focus on the open bay side of the beach where ocean swell keeps the water cleaner. Fishing improves within a day or two after a storm passes and the water clears.
Tackle and bait for shore fishing
A 7- to 8-foot medium-action spinning rod with 15- to 20-pound braided line handles the rocky bottom and the range of species. Bring a small tackle box with a mix of swimbaits (2 to 4 inches), soft plastics in natural colors, and a few topwater plugs for striped bass. If you plan to use live bait, bring a small aerator or bait bucket; live anchovies and mullet are sold at tackle shops in Watsonville and Aptos, both within 20 minutes of the beach.
The rocky terrain demands heavier sinkers than you might use on a sandy beach — 1 to 2 ounces is common to keep your bait in place. Bring extra hooks (size 2/0 to 4/0 for live bait, smaller for soft plastics) and leaders; the rocks will cut through light line. A small net is useful for landing fish in the shallows, especially corbina and halibut that can thrash free on the rocks.
Tides, weather, and timing
Twin Lakes fishes best on the incoming tide, roughly the last two hours before high tide. The rising water pushes baitfish toward shore and activates predators. Low tide exposes the rocky structure but also makes wading dangerous and limits where fish will hold. Plan your visit around the tide table — NOAA publishes tide predictions for Monterey Bay, and the Pajaro River mouth follows the same schedule as the open bay.
Wind and swell matter more here than at protected bays. A south or southeast wind pushes water onto the beach and can improve fishing; a strong north wind creates choppy conditions and can make the beach uncomfortable. Check the marine forecast the night before. Swell direction also affects water clarity: west or northwest swell tends to stir up the bay, while south swell keeps it cleaner. Early morning (first light through mid-morning) usually offers the calmest conditions and the clearest water.
Access, parking, and regulations
Twin Lakes State Beach is day-use only; there is no camping. The parking lot is small and fills on warm weekends, so arrive early if you are fishing on a Saturday or Sunday. The day-use fee is collected at the entrance; bring cash or a card, depending on what the park accepts that day. Check the California State Parks website before you go to confirm current hours and fees.
California fishing regulations apply: you need a valid fishing license (available online or at any tackle shop), and there are daily bag limits and size restrictions for each species. Striped bass have a minimum size of 18 inches and a daily limit of two fish. Halibut and corbina have their own minimums and limits that change slightly by region; the ranger station or a local tackle shop can confirm the current rules. Leopard sharks are not regulated by a daily limit but have a minimum size of 36 inches.
Nearby tackle and services
The closest tackle shop is in Aptos, about 15 minutes north: Aptos Seascape Resort and the local bait shops carry live anchovies, frozen mackerel, and basic tackle. Watsonville, inland about 20 minutes, has a few shops with a wider selection of rods and reels. If you forget something, do not count on finding it at the beach — bring what you need or plan a stop on the way.
There is a small restroom at the parking lot but no food vendors or water fountains. Bring water, snacks, and sunscreen. The beach can be windy and exposed, so a light jacket or windbreaker is useful even on warm days. Parking is the only service at the site itself; plan accordingly.
When to avoid Twin Lakes
Heavy rain makes the Pajaro River mouth murky for several days, and the bay side can also cloud up from runoff. If the forecast calls for rain, wait a day or two after it passes before fishing. Extreme low tides (below -1 foot) expose so much rock that wading becomes risky; check the tide table and avoid fishing during the lowest hours. High summer heat (July and August) can slow fishing in the afternoon, so plan an early morning or evening session instead.
Winter storms occasionally close the beach temporarily for safety reasons. Call the ranger station or check the California State Parks website if you are planning a winter trip. The beach can also be crowded with swimmers and families on warm weekends, which does not help fishing; weekday mornings or cooler-weather days offer better conditions and fewer people.
Frequently Asked Questions
Do I need a boat to fish Twin Lakes?
No. Twin Lakes is a shore-fishing-only beach. You can fish from the sand and rocks along the entire beach without a boat. The bay is shallow enough that shore casting reaches productive water, especially near the river mouth and along the rocky points.
What is the best time of year to fish here?
Fall and early winter (September through December) are best for striped bass and leopard sharks. Late spring through early fall (May through September) is better for halibut and corbina. Each season has active fish; it depends on what species you want to target.
Can I keep fish I catch at Twin Lakes?
Yes, if they meet California size and bag limits. Striped bass must be at least 18 inches and you can keep two per day. Halibut and corbina have their own minimums; check with a local tackle shop or the ranger station for current rules, as they can change by region and season.
Is there parking and a fee?
Yes. There is a small parking lot with a day-use fee (currently around $10 per vehicle). The park is day-use only, so you cannot camp. Bring cash or a card, and arrive early on weekends because the lot fills quickly.
What happens if the river is muddy after rain?
Fish the open bay side of the beach instead. The ocean swell keeps that water clearer than the river mouth. Wait a day or two after rain stops for the river to clear, or focus on the bay side until conditions improve.
