When It Rains, the Whole Palos Verdes Nature Preserve Closes. Here's How the Last Two Seasons Went.

"Effective October 14, 2025, the City is temporarily closing the entire Palos Verdes Nature Preserve and Abalone Cove Park due to significant rain fall." That was the City of Rancho Palos Verdes in a CivicSend alert last October, and the important word is "entire." The Preserve doesn't close one muddy trail at a time. On the first real storm of the season, every reserve goes off-limits at once, along with Abalone Cove Park.

Rain started early this season. On September 8, 2026, the City closed the Preserve and Abalone Cove Park for rain, and both reopened the next day, September 9. As the wet months begin, how the closure rule works matters for anyone who hikes Portuguese Bend before work or walks the dog at Abalone Cove.

The rule closes everything and puts a floor on reopening, not a deadline

The September notice said trails "may remain closed up to 48 hours after the last rainfall." Two parts of that sentence matter.

First, the clock starts when the last rain stops, not when the first rain falls. If a storm lingers or a second front follows close behind, the 48 hours keep resetting.

Second, the 48-hour figure is guidance, not a promise. A City rain notice from January 2018 said trails can open sooner or later than 48 hours depending on conditions. The City's Spring 2019 newsletter used the phrase "up to 48 hours or more after the last rainfall." The wording hasn't always matched, either. The March 12, 2025 closure notice said up to 72 hours. The December 2025 and September 2026 notices went back to 48. None of the notices explain the change. The trails reopen when the City posts a separate notice saying so.

Why a whole preserve closes for one storm

The City's reasoning appears in its Spring 2019 newsletter, in a piece titled "Don't Rain On My Parade Trail." Most Preserve trails are dirt. Light rain helps by keeping the dust down. Heavier rain over hours or days turns them muddy, leaves standing water, and erodes them. The newsletter puts it this way:

Patrons using trails when they are wet can cause damaging ruts and widen the paths when they bypass the muddy areas by stepping through the adjacent habitat.

So the closure protects the land around the trails as much as the trails themselves. Each hiker who steps off the path to avoid a puddle widens it a little and pushes into the plants beside it. According to the newsletter, City staff check trail conditions, close trails when warranted, and put closure signs at most trailheads. Note the word "most." Finding no sign at the trailhead you use doesn't mean the trail is open.

Two seasons, notice by notice

Lined up in order, the City's CivicSend alerts show how a Preserve rain season actually goes. These are the closure and reopening notices from the past two seasons, with the effective date each one printed:

Three things stand out.

The gap between closing and reopening varies a lot. The September 2026 closure lasted one day. In March 2025, the reopening notice came four days after the closure. In winter, the next reopening notice after the Christmas Eve closure was dated January 8, 2026. Not every closure has a matching reopening alert in the list. The October 14, 2025 closure was followed by another closure notice on November 14, so the Preserve probably reopened in between without a notice above recording it. Look at the date on any alert before you plan around it.

The fall closures came in October and November. Last year the first fall closure took effect October 14, and the next came a month later. This year's September notice came more than a month ahead of that.

A reopening doesn't mean every trail is open. Each reopening notice from November 2025 on includes the same warning: several temporary trail closures may stay in effect. The Preserve as a whole can be open while your usual loop is still roped off.

Abalone Cove follows the same switch, with its own rules on top

Abalone Cove Park is named in every closure and reopening notice above, so it opens and closes with the Preserve. It also has its own operating details that apply on dry days. According to the City's Abalone Cove Shoreline Park page, the park is open from one hour before sunrise to one hour after sunset. The parking lot is open 9 a.m. to 4 p.m. and closes on January 1, Thanksgiving Day, and December 24 and 25. Parking is credit or debit card only. The first 30 minutes are free, 30 minutes to two hours costs $6, and longer stays cost $12. Parking is free year-round for seniors 62 and older and for people with disabilities.

The beach has a separate status. The same City page still shows a notice dated July 9, 2024, closing Abalone Cove Beach, Sacred Cove Beach, and all beach-access trails in Abalone Cove Reserve until further notice because of land movement, while the park itself stays open on its regular schedule. The Preserve reopening notices cover the Preserve and the park. They don't mention the beach or the beach-access trails, so a reopening alert doesn't reopen the sand. Check the facility page itself before planning a trip down to the water.

How to check before you lace up

Because every closure and reopening is posted as its own alert, the fastest way to check is to go straight to the City.

1. Trail Conditions & Alerts. Every notice points to rpvca.gov/trailalerts, which the City says lists temporary trail closures. The November 2025 notice says it also has a map of trail closures.
2. The phone line. The Open Space and Trails Division can be reached at 310-491-5775, the number printed on each notice.
3. CivicSend alerts. Closures and reopenings go out as dated CivicSend messages like the ones linked in the table above. Signing up means the notice comes to you.
4. The trailhead itself. Signs go up at most trailheads, not all of them. Take the sign as confirmation, not as your only check.

Dry-weather plans on the late-October calendar

The Palos Verdes Peninsula Land Conservancy's late-October calendar includes a few events worth planning around, depending on the weather.

• Outdoor Volunteer Day at Abalone Cove Reserve, Saturday, October 31, 9:15 a.m. to 12:15 p.m., 5970 Palos Verdes Dr. S., according to the PVPLC events calendar. This one is in Abalone Cove, so check trail status that morning.
• Halloween Dog Parade, Saturday, October 31, at 11 a.m. at White Point Nature Preserve, 1600 W. Paseo del Mar in San Pedro, as listed by Palos Verdes Pulse.
• Storytime Tails, "Remarkable Reptiles," Sunday, November 1, 10:30 to 11:30 a.m. at the White Point Nature Education Center.
• 1st Wednesday Bird Walk, November 4 at 9 a.m., also at White Point.

According to Palos Verdes Pulse, the Conservancy also trains Wildlife Tracking Volunteers to monitor signs of foxes and coyotes in the Palos Verdes Nature Preserve. Volunteers must be at least 16, pre-register, and attend both training sessions to be certified. Registration is through the PVPLC VolunteerHub. Event times can change, so confirm with the Conservancy before you go.
