On Monday, November 2, how late can you start up Bishop Peak after work and still be off the mountain legally? Daylight saving time ends Sunday, November 1, 2026. Sunset in San Luis Obispo that day is 5:07 p.m., according to timeanddate's 2026 sun tables. City open space closes one hour after sunset. On the first evening of standard time, that means you have to be off the trail by about 6:07 p.m.
From then until March, the city's open space system works differently after dark. Most of it closes. One mountain stays open by permit, and the cap on that permit is a number the city counted in 2015, when people were already hiking it after hours while it was closed.
The Rule That Returns Every November
The rule is the same all year. San Luis Obispo Municipal Code 12.22.050(B) opens open space lands "from dawn to dusk." It also makes it unlawful to enter or stay on them "between one hour after sunset and one hour before sunrise of the following day without approval from the director." In summer, a 7:30 p.m. start on a long evening barely brushes against it. After the time change, it sets your evening.
Here is how the legal cutoff moves through the darkest weeks, using timeanddate's sunset times plus the one-hour allowance:
- November 1: sunset 5:07 p.m., open space closes about 6:07 p.m.
- December 1: sunset 4:50 p.m., open space closes about 5:50 p.m.
- December 31: sunset 5:00 p.m., open space closes about 6:00 p.m.
If you leave work at 5:00, there's very little time left. The city's reason for the rule is wildlife. The Winter Evening Access page says the evening hours are when rodents come out to forage, owls hunt them, and bats feed on flying insects.
One Mountain, Sixty-Five People
The exception is Cerro San Luis Natural Reserve, the mountain with the Mission Prep "M." The Winter Evening Access program returns November 1, 2026. During standard time, which runs November through March, it allows up to 65 permits per day for roughly 4.9 miles of designated trails on city property. Permit holders can hike or bike from one hour after sunset until 8:30 p.m. Nothing else is allowed.
The number 65 has a history. The city explains that in its 2015 Open Space Survey, the reserve averaged 65 people a day between 6:00 and 9:00 p.m., "despite the City's existing Open Space Regulations provision that open space is closed one hour after sunset." The permit cap was set at that existing baseline. The city didn't grow nighttime use. It made legal the level of use the mountain was already getting, and then kept it there.
The share of land involved is small. When the program became permanent, Mayor Erica Stewart described it to New Times San Luis Obispo as "less than 3 percent of our 4,000 acres" of open space.
How a Head Count Became an Ordinance
The program started as a pilot in 2018, after feedback that the open space hours gave 9-to-5 workers little chance to hike or bike on winter evenings. Making it permanent took two tries. New Times reported that at an October 19, 2021 meeting, the City Council held off on the ordinance after heavy public opposition, part of which questioned the environmental review. On November 9, 2021, it passed 3–2.
According to New Times, Stewart was the swing vote. She put the case this way:
"Why do we want to have people drive out of our community to be able to get exercise after work, to be able to enjoy the beauty of our community after work?"
Councilmembers Andy Pease and Michelle Shoresman voted with her. Jan Marx and Carlyn Christianson voted no. Marx said she saw the program as a precedent that put recreation ahead of conservation in the city's natural reserves. The same New Times report says residents who questioned the ordinance raised concerns about how the 65-person baseline was set, the fact that nighttime use was studied only on the 118-acre city-owned part of the mountain, and how impacts on wildlife were weighed.
That history explains why the program hasn't grown since. Its legal basis is a cap tied to past use on one reserve, so there's no automatic route to adding Bishop Peak or the Irish Hills. The program has run each winter since then. The San Luis Obispo Tribune reported that the 2025–26 season ran November 2 through March 8, 2026, with 65 permits available each night.
Getting a Permit This Season
Some news coverage, including a 2023 KSBY report, has said access starts at sunset. The city's current page says the permit is required starting one hour after sunset, which matches when the regular open space hours end. Here's how it works:
- Reserve online. The city says the reservation system opens one week before the program starts November 1. Permits are issued through the city's Winter Evening Access permit form.
- Download the evening map. The city publishes a Winter Evening Access version of the Cerro San Luis map. In the city's words, "most daytime landmarks and reference points are no longer visible" after dark.
- Bring a light and know your intersection numbers. The city's tips include a flashlight with spare batteries, lights and a bell for bikes, and noting the numbered blade signs at trail intersections so you can give 911 dispatch your location in an emergency.
- Know the standard rules. Dogs stay on leash, bikers yield to hikers, and the usual open space rules apply: no alcohol, no amplified sound, no fires.

The Rest of the Evening Map Is Short
Off the mountain, the official after-dark options are few and mostly lit. Meadow Park's city facility listing includes lighted basketball and pickleball courts, lighted volleyball courts, and lighted pedestrian trails. That makes it the clearest city park option for a walk after 6:00 p.m. French Park, by comparison, is listed as dawn to dusk.
The SLO Swim Center is an outdoor pool open year-round. Its posted fall schedule has weekday lap swimming from 5:30 to 7:00 p.m. and family recreation swim from 5:30 to 6:50 p.m. That schedule runs through November 29 and may change, so the winter hours after that date haven't been published yet.
One flat, familiar route is also affected. The city's Ranger Service says the Bob Jones Bike Trail between Prado Road and Los Osos Valley Road will close for about three months "as early as Monday, October 5, 2026." The listed work includes fence repairs, gate installation, new signage, creek embankment clearing and tree trimming, with reopening estimated for early January 2027. That start date has passed. The same page still uses future-tense wording for the closure while showing the project with the green marker its legend uses for "Complete/Open," and no detour has been posted. Check the Ranger Projects page for current status before heading out.
The Daylight Network Kept Growing
While the evening system stays at one mountain, the daytime trail network has added a lot this year. That matters more in winter, when weekends carry more of the outdoor time.
- Backburn Trail, Reservoir Canyon. It's open to the public while construction continues, with 2.6 of 3.2 miles complete. Once finished, it will reach the summit as "a mellow alternate" to the steep Firefighter Trail. Access is from the end of Lizzie Street, across from French Hospital.
- Stenner Flow, Stenner Springs Natural Reserve. Rangers and volunteers rebuilt the lower section, the first major overhaul since it was built by hand in 2014. It reopened in June as a bikes-only directional trail. Hikers use Elevator Trail.
- Laguna Lake Bike Park. Phase 2 is complete, with two full jump lines and a mulch jump for 11 jumps in total. A beginner jump line for young riders is under construction.
- Miossi Open Space. Planning and mapping have started on extensions and improvements to the Hi-Bar and Panorama trails, with construction projected to begin late this year or early next year.
Rangers hold volunteer trail days on Wednesday mornings at Backburn. Sign-ups are at volunteer.slocity.org.
The Last Long Evenings of October
Two city events fall in the weeks before the time change. As part of the Greenbelt's anniversary, the city offered a limited-edition bandana to residents who visit all 12 city open spaces before the end of October. A September 18 announcement called it a last chance and said only a very limited number were left. On October 30, Meadow Park hosts the free Boo Bash from 4:00 to 8:00 p.m., with games, food trucks, a movie and a haunted house that has sensory-friendly and lights-on times. The next night is the last before the clocks change, and the night after that, Cerro San Luis's 65 permits go into effect.
