Bike Fire Reaches 200 Acres and Triggers Santa Clarita Evacuations

A fast-moving wildfire in the Sand Canyon area of Santa Clarita, California, grew to approximately 200 acres on Sunday, October 11, 2026, prompting evacuation orders and warnings for nearby communities. Fire crews responded to the blaze, known as the Bike Fire, as erratic winds and rapid uphill spread threatened homes near the fire zone, according to local news reports and Angeles National Forest officials.

The Los Angeles County Fire Department estimated the fire had reached 200 acres by approximately 2:34 p.m., according to CBS News. Earlier updates from local station KHTS reported that the blaze had expanded from an initial one-acre estimate to 75–80 acres before continuing to spread.

Firefighters initially received reports of the blaze around 1:08–1:10 p.m. near the 16400 block of Cambria Estates Lane, close to Ravenhill Road in Sand Canyon. The fire was burning uphill toward the west through brush, and officials requested additional firefighting resources as conditions became increasingly difficult.

According to KHTS, the incident was elevated to a third-alarm response after erratic winds accelerated the fire's spread. Structures near Pineview Road, Mountain Park Road and Falter Road, and Pacy Road were reported to be threatened during the afternoon.

Authorities also began mobilizing aircraft to assist ground crews. The Angeles National Forest reported that aircraft were being deployed by 2:08 p.m. as firefighters worked to contain the growing blaze.

Evacuation warnings covered several communities and designated zones, including Crystal Springs, Woodland, Sandsouth, Nadeu, MacMillan, Fair Oaks Ranch, Medley Ridge, and Rolling Hills. The reported evacuation zone designations included LAC-E119-A, SCL-CRYSTALSPRINGS, SCL-FAIROAKSRANCH, SCL-MACMILLAN, SCL-MEDLEYRIDGE, SCL-NADEU-B, SCL-ROLLINGHILLS-B, SCL-SANDSOUTH-A, and SCL-WOODLAND.

Earlier evacuation updates from Angeles National Forest officials specifically identified areas of Nadeu, Sandsouth, Woodland, MacMillan, and Crystal Springs. The designated areas and evacuation instructions were updated as the fire grew, according to KHTS and CBS News.

The fire's cause remained undetermined as of Sunday afternoon, according to CBS News and the Sacramento Bee. The Sacramento Bee reported that the wildfire was burning on private land in Los Angeles County, while officials had not established a containment status in the initial report.

As the afternoon progressed, the fire's estimated size increased sharply, with KHTS reporting at 2:35 p.m. that it had reached 200 acres and was spreading rapidly. Authorities continued responding to the incident as evacuation measures remained in effect and the extent of the threat to nearby properties developed.
