Common questions

Pinnacles month by month: notes from the park service

• January: January at Pinnacles is cold at night, the park says, with lows that can drop into the low 20s°F and small amounts of snow at higher elevations almost every year between mid-December and January. Wet years can bring the first flowers, such as manzanita, milkmaids and shooting stars.
• February: February is usually Pinnacles' wettest month, averaging about 4 inches of rain, and the park advises warm layers and a light rain jacket. In heavy rain, take care at stream crossings and ask a ranger about the Balconies Cave Trail.
• March: Pinnacles has two separate entrances, and in March as all year they work differently. The east side is open around the clock for trails, and it is the only side with camping: the Pinnacles campground is booked on recreation.gov.
• April: Plan an April weekend at Pinnacles around parking. The park service says it gets extremely high visitation on weekends, holidays and whenever the weather is good, with delays most likely between 10 a.m. and 3 p.m.
• May: May at Pinnacles shifts its wildflowers toward plants that like hotter, drier weather, the park says: chamise, buckwheat, clarkias, penstemons and roses. Plan around the caves: from mid-May to mid-July all of Bear Gulch Cave closes while the Townsend's big-eared bats raise their young, the largest maternity colony between San Francisco and Mexico.
• June: June at Pinnacles falls inside the pupping season, so Bear Gulch Cave is fully closed until mid-July to protect its bat colony; check the park's cave-status page, since closures can also follow flooding or rockfalls. By mid-June the summer heat sets in and few flowers remain except in wet or cool years.
• July: July at Pinnacles often tops 100°F in the day, then drops to around 50°F at night, a swing the park puts down to its inland location away from the coast. Dehydration is among the most common emergencies rangers respond to, so carry plenty of water and cover up from the sun.
• August: August is typically Pinnacles' driest month, with close to no rain on average, and days over 100°F are not unusual. The park recommends a hat, sunscreen and light long sleeves and trousers on its exposed trails.
• September: September keeps Pinnacles in its dry season, which the park says lasts until early October, so start hikes early and carry water. Fall, along with spring, is the park's most pleasant time for hiking.
• October: October brings Pinnacles' rainy period back, starting in early October and lasting until early May. It is also one of two months, with March, when the whole of Bear Gulch Cave usually opens, generally for the last week of October and sometimes for the full month, depending on the bats.
• November: Pinnacles in November: the east side is open for trails around the clock and has the park's only campground, booked through recreation.gov, while the west side gate opens 7:30 a.m. to 8 p.m. for day use. The park service says it gets extremely high visitation on weekends, holidays and good-weather days, with delays most likely from 10 a.m. to 3 p.m., so Thanksgiving weekend is a day to arrive before 8 a.m. for the popular trails.
• December: December at Pinnacles: the park's visitor contact points keep daily hours (West Pinnacles Visitor Contact Station 9 a.m. to 3 p.m.; East Pinnacles Park Store 9 a.m. to 4 p.m., closed for lunch from noon to 1 p.m.), while the Bear Gulch Nature Center opens only intermittently because of staffing. Holiday weekends draw crowds, the park service says, so come early for the High Peaks, Condor Gulch, Balconies or Moses Spring trailheads.
