When the Clocks Fall Back, the Wilderness Park Becomes a Morning Trail

Through Saturday, the gate at Claremont Hills Wilderness Park opens at 6:30 a.m. and closes at 6:00 p.m. On Sunday, November 1, the City's posted hours change to 6:00 a.m. to 5:00 p.m. That same Sunday at 2:00 a.m., Daylight Saving Time ends and clocks fall back one hour.

So the gate opens half an hour earlier and closes an hour earlier. The park's day moves toward the morning on both ends, and the November schedule tracks the light almost minute for minute. For anyone in Claraboya who uses the Loop, Johnson's Pasture or Thompson Creek Trail, November is a morning month.

The Gate and the Sun, Side by Side

The City's hours table lists one schedule per month. Timeanddate's November 2026 table for Claremont shows how far the light moves inside that month.

On November 1 the gate closes three minutes after sunset. By November 30, sunset is at 4:41 p.m. and the gate closes 19 minutes later, while some twilight is still left. In the evening, the posted close follows sundown closely all month.

Mornings work out differently. In early November the gate opens about 15 minutes after civil twilight begins and 10 minutes before sunrise. Around November 19 the two line up at 6:00 a.m. After that, the gate opens before civil twilight starts. By the last day of the month, someone walking in at opening time has 37 minutes until sunrise.

What Happens to the Afternoon Hike

In October, a 6:00 p.m. close left room for a walk after the workday. In November, the park closes at 5:00 p.m. and sunset comes earlier every day. The full Loop is long, steep and rugged, and the City reminds visitors there is no safe drinking water past the entrance. Fitting the full Loop between the end of a workday and a 5:00 p.m. gate is a real squeeze, and the City says visitors who break park hours may be cited.

The cost of being late goes up too. The park gets more than 450,000 visits a year, by the City's count. In November, more of that traffic shares the same few daylight hours. On weekdays, the morning window from 6:00 a.m. to mid-morning gets bigger on the clock. The evening window is gone.

Parking Rules Point to the Same Hours

The Mills Avenue lots charge by the block, according to the City's Wilderness Park parking page. Both the main Wilderness Park lot and the Thompson Creek Trail lot sell four-hour and six-hour blocks.

Two details matter more in November than at other times of year.

1. The holiday rate covers Thanksgiving week. The City groups weekends and holidays together, so Thanksgiving Day costs the same as a Saturday. A weekday-morning walk costs about half as much as the same walk on a holiday.
2. Resident parking is free in the south lot only. Claremont residents get six free hours a day in the Thompson Creek Trail lot, also called the South lot, at Mt. Baldy Road and Mills Avenue. The process happens at the meter. You scan a valid California driver's license with a Claremont address and enter your plate. You don't apply ahead of time, and the old cap of two permits per household is gone. The benefit doesn't apply in the main lot.

The City lists the annual permit at $185 a year. Your license plate serves as the permit, and the pass is good for 365 days from purchase. The City also says annual permits aren't valid when the park is closed for hazardous conditions. Those closures happen. The City's visitor page posted a closure from October 15 through October 17 this month. The visitor page is where the City posts closure notices.

Walking In From Claraboya

For many Claraboya addresses, a dawn start doesn't need a parking lot at all. The City describes the 2.8-mile Thompson Creek Trail as having several access points, including Pomello Drive, several cul-de-sacs, Base Line Road, Higginbotham Park and North Indian Hill Boulevard. The Wilderness Park Master Plan, printed in 2016, adds entry points at the park's southwest corner off Via Santa Catarina and Highpoint Drive. It also notes that Thompson Creek Trail connects to Sycamore Canyon. The plan points out that none of these entries has parking.

That missing parking applies to visitors as well as residents. The City warns that parking in the neighborhoods around the park is restricted and that violators may be cited. A walk-in start from home doesn't involve parking at all.

The land behind those entrances has also grown. In June 2025, the City and the Claremont Wildlands Conservancy protected the 80-acre Seaver and Jaffe parcels above Claraboya, along the west edge of Johnson's Pasture, and added them to the Wilderness Park. The $3.8 million purchase combined a $3 million state Rivers and Mountains Conservancy grant, nearly $400,000 from the Conservancy, $400,000 from the City and $25,000 from Supervisor Kathryn Barger's office. The City's announcement doesn't name a new trailhead there, so the acquisition preserved the land behind the neighborhood without adding a new way in.

Rules That Matter More in Low Light

Walking in the dark part of twilight brings a few posted rules to the front. The rule list and trail etiquette standards on the City's Wilderness Park visitor page, which draw on Claremont Municipal Code Chapter 11, include these:

• Dogs must stay on a leash shorter than six feet at all times.
• Bike and e-bike riders yield to pedestrians and equestrians, and pedestrians yield to equestrians.
• Riders must use a bell or call out when passing, and must watch their speed downhill and on curves.
• No one may wear earphones in, on or covering both ears.
• Stay on the designated fire-road trails.

E-bikes have their own rule. Under the ordinance described on the same City page, which took effect May 22, 2025, the City allows manual bikes and Class 1 and Class 2 e-bikes in the park. Class 3 e-bikes, Surron-type cycles, scooters, skateboards and other motorized devices are banned. This is general information, not legal advice. Check the City's current posted rules before you rely on them.

A November Built Around Mornings

The month's nearby events follow the same daylight pattern.

• Sunday, November 1, 8:00 to 10:00 a.m. The California Botanic Garden and the Pomona Valley Bird Alliance host a free, family-friendly First Sunday bird walk. It meets at the Garden entrance, 1500 N. College Ave., and requires advance registration. It's the first morning of standard time, so 8:00 a.m. comes well after sunrise.
• More California Botanic Garden programs. The Garden's events listing includes Mixed Media Mushrooms & Moss on November 7, a Cacti and Succulents Walking Tour on November 8, Nerd Out at the Garden on November 14, a free gardening mini-workshop on designing with salvias on November 15, and a free mini-workshop on watering and irrigation for succulents on November 27.
• Second Saturday at the main gate. The Friends of the Claremont Hills Wilderness Park run a recurring Second Saturday program. Volunteers greet visitors, share trail information and pick up trash, starting from the main gate. Preregistration is required. The October session ran from 7:30 to 9:30 a.m.
• Invasive plant removal season. The same group removes invasive plants once a month from October through April and monitors monarchs and milkweed in Johnson's Pasture. Details are on its volunteer page.

The City's December hours open the gate at 6:30 a.m. again and keep the 5:00 p.m. close. That makes November the only month of the year with a 6:00 a.m. opening and a 5:00 p.m. close.
