Big Basin Redwoods State Park

The Headquarters Administration Building of Big Basin Redwoods State Park, Santa Cruz County, California, was a historic structure built in 1936 by crews of the Civilian Conservation Corps. It was built out of local materials (redwood logs and stone), and was one of the best-preserved examples of the CCC's work in the California state park system. The building continued to perform its original function, housing the park's administrative offices and serving as a contact point for park visitors, until it was destroyed by the wildfires sparked by the lightning storm of August 16, 2020. It was listed on the National Register of Historic Places in 2017, and was delisted in 2023.

The Skyline-to-the-Sea Trail is a 29.5-mile (47.2-kilometre) hiking trail that descends from the ridge of the Santa Cruz Mountains in California to the Pacific Ocean, passing through Castle Rock State Park and Big Basin Redwoods State Park. Big Basin is California's oldest state park. It contains beautiful waterfalls and some of the largest, tallest, and oldest Redwood forests left in existence. After the August 2020 CZU Lightning Complex fires, the trail closed, along with much of Big Basin Redwoods State Park. As of December 2021, the trail remains closed and its future is unclear.The trail usually takes two to three days to complete, with nearly all thru-hikers traveling from East to West (towards the ocean). It is possible to walk the entire trail in one day, though this is unusual and very difficult. However, there is a 50-km (31-mi) ultra running race held on this trail one or two times per year. Many hikers like to take a detour up Berry Creek Trail to see the waterfalls or to camp at Sunset Trail Camp, adding 2.7 mi (4.3 km) to the hike. The trail begins at Saratoga Gap on the ridge at the intersection of SR 9 and Skyline Boulevard (SR 35), although many hikers actually begin at Castle Rock due to its overnight parking facility. The trail parallels SR 9 through Castle Rock, crosses the highway, and then follows SR 236 to Big Basin park headquarters. It then descends through Big Basin, following Waddell Creek to its outlet at Waddell Beach. Santa Cruz Metro routes 35 and 40 formerly went from Big Basin State Park Headquarters to Waddell Creek and back. Since September 2011, Route 40 no longer goes all the way to Waddell Beach from mid-December to mid-March. but instead turns around at Cement Plant Rd. Route 35 formerly stopped at Big Basin Headquarters on the weekends during the Spring/Summer season. As of October 2020, there is 3.6 mile (5.8 km) extension that creates a "Saratoga-to-the-Sea" Trail. The trail originates at Saratoga Quarry Park, and terminates at Sanborn-Skyline County Park. This trail connects to the Skyline-to-the-Sea Trail via a completed section of the Bay Area Ridge Trail. The park is owned by the city of Saratoga's Parks Department.

The CZU Lightning Complex fires were wildfires that burned in Northern California starting in August 2020. The fire complex consisted of fires in San Mateo and Santa Cruz counties, including fires that had previously been separately tracked as the Warnella and Waddell fires. The firefighting effort was primarily administered by the California Department of Forestry and Fire Protection (Cal Fire).The first fires started around 3:30 A.M. on August 16, 2020, the result of a thunderstorm that produced close to 11,000 bolts of lightning and started hundreds of fires throughout California. These lightning strikes initially started fires separately known as the Warnella Fire, near Davenport and the Waddell Fire, near Waddell Creek, as well as three fires on what would become the northern edge of the CZU Complex fire. Two days after the fires began, a change in wind conditions caused these three northern fires to rapidly expand and merge, growing quickly to over 40,000 acres.The fires destroyed 1,490 buildings, including in the communities of Boulder Creek, Bonny Doon, Swanton, and along Empire Grade Road. Fires burned in both Butano and Big Basin Redwoods state parks, where a number of historic buildings were destroyed, including the visitor's center at Big Basin.On September 22, Cal Fire reported that the complex, which had covered 86,509 acres (35,009 ha), had been fully contained On December 23 Cal Fire announced that the fire was controlled, stating that the fire was fully extinguished and has no risk of reignition. However, it was later discovered that the fire was not quite completely extinguished; redwoods continued to smolder well into 2021. The abbreviation "CZU" refers to the Cal Fire designation for its San Mateo–Santa Cruz Unit, the administrative division for San Mateo, Santa Cruz and San Francisco counties.One person died in the fires, and one other was injured.The documentary The CZU Fire In Their Own Words – Fighting Fires, Losing Homes, and Rebuilding Community covers the fires and was created and directed by Boulder Creek resident Peter Gelblum .

Little Boulder Creek is an eastward-flowing stream in the Santa Cruz Mountains of California. Rising in Santa Cruz County near Big Basin Redwoods State Park, it crosses into San Mateo County and empties into Pescadero Creek.

Waterman Creek is a 3.0-mile-long (4.8 km) southward-flowing stream in southern San Mateo County, California. Rising near Big Basin Way and the Santa Cruz County line, it empties into Pescadero Creek.In 2008, a conservation organization awarded $32,000 to the San Mateo County Farm Bureau to fund removal of a 12-foot (3.7 m) high, 100-year-old log dam that was preventing steelhead from accessing potential spawning grounds in the upper reaches of the creek.

Oil Creek is a small river in San Mateo County, California and is a tributary of Pescadero Creek.

Slate Creek is a small river in San Mateo County, California, and is a tributary of Pescadero Creek.

Iverson Creek is a small river in San Mateo County, California and is a tributary of Pescadero Creek. It flows about 0.6 miles (1 km) from its source on Butano Ridge in Pescadero Creek County Park to its mouth in Portola Redwoods State Park.

Tip Toe Falls (also known informally as Tiptoe Falls), is a 6-foot (1.8 m) tall waterfall (though commonly mismeasured from 5 to 8 feet (1.5 to 2.4 m)) on Fall Creek in the Portola Redwoods State Park, California. There is also an 8-foot (2.4 m) upper falls, a few hundred feet upstream, which is much lesser known. The falls, fed by Fall Creek (a tributary of Pescadero Creek) starts by cascading down a mossy, 8 foot (2.4m) upper tier into a small pool. The creek continues downstream between grassy banks, and before long, falls over the more well known, 6 foot (1.8 m) lower tier. The lower tier empties into a round pool approximately 6” deep, before the creek cascades over sticks and rocks and continues its way downstream.

Fall Creek is a small river in the Santa Cruz Mountains, in San Mateo County, California. It is a tributary of Pescadero Creek.The creek flows through a Coast Redwood (Sequoia sempervirens) forest in its short course through a narrow canyon. It is a left-bank tributary of Pescadero Creek and is perennial, being fed by rain in the winter and by fog drip in the summer and fall. Near its mouth, the creek plunges over Tip Toe Falls, a series of two waterfalls that has a total drop of 14 feet (4.2m).

Peters Creek is a 7.3-mile-long (11.7 km) stream in San Mateo County, California, and is a tributary of Pescadero Creek. It flows southwestwards through a small canyon to join Pescadero Creek in Portola Redwoods State Park, near La Honda.
