A Responsible Big Basin Day Trip From Boulder Creek

The short version

• Big Basin Redwoods State Park is open for limited day use, 8 a.m. to sunset. All campgrounds in the main park are closed.
• The main entrance is about 9 miles up Highway 236 from downtown Boulder Creek, roughly a half-hour drive on a narrow, curvy road.
• Parking reservations are strongly recommended: $6 per regular vehicle plus a $2 reservation fee, or $10 per vehicle without a reservation.
• The park is still recovering from the 2020 CZU fire, so what's open changes regularly. Facilities are limited, so bring your own water, food, and layers.
• Check the official Big Basin Redwoods State Park page before you drive up. That page, not this one, is the source of truth for current conditions, and nothing here is a guarantee of access.

A Big Basin day trip from Boulder Creek is easy to plan and easy to get wrong right now. The park is still recovering from the 2020 CZU fire, so facilities are limited and a trail that was open last month may be closed today. None of that makes it a bad day out. It just means a little planning goes further than it used to. Here's how to put the day together.

Know what you're visiting

Big Basin became California's first state park in 1902, and Boulder Creek has been its gateway town ever since. Then, in August 2020, the CZU Lightning Complex fire changed everything. Per CAL FIRE's incident record, the fire burned 86,509 acres across Santa Cruz and San Mateo counties. It reached Big Basin two days after igniting and, according to Friends of Santa Cruz State Parks, burned roughly 18,000 acres inside the park, over 97 percent of it, and destroyed nearly every structure, including the historic Park Headquarters.

The recovery is real, though. State Parks reports that most of the old-growth redwoods survived, new growth is coming in fast, and wildlife has returned. The park reopened for limited access in July 2022, and Sempervirens Fund notes that access has kept evolving since, shaped by both the fire and the severe storms of 2023.

You won't find the shaded, built-out Big Basin of the old photos. You'll find something rarer: an old-growth forest rebuilding itself in the open sun, with new trail mileage opening in phases. So set your expectations accordingly. Facilities are limited, shade is thinner than it used to be, and a trail that was open last month may be closed today.

Reserve your parking before you go

Day-use parking reservations are highly recommended. State Parks lists regular-sized autos at $6 plus a $2 reservation fee, or $10 per vehicle without a reservation, and parking is limited enough that showing up without one is a gamble on busy days. Book through the Big Basin parking reservation page run by Friends of Santa Cruz State Parks. Passenger vehicles use the main form; disabled parking and bus or horse trailer parking have separate reservations.

Two more parking notes. Oversized vehicles and trailers can't be accommodated for day use right now, so leave the RV at camp. And fees or rules can change, so confirm current pricing on the official park page when you book.

Getting there from Boulder Creek

From downtown Boulder Creek, turn onto Highway 236 (the Big Basin Highway) and follow it about 9 miles to the main entrance. Every road into Big Basin is curvy, and lower 236 is narrow, so give yourself 25 to 30 unhurried minutes, watch for cyclists, and use the turnouts if you're holding up locals.

If you'd rather not drive in, two alternatives are worth checking. On summer weekends between Memorial Day weekend and Labor Day weekend, State Parks has run a free pilot shuttle from the Saddle Mountain temporary parking area along Highway 236 to the main day-use area. And Santa Cruz METRO's Route 35B offers weekend bus service to the park. Both are subject to schedules and seasons, so verify each is running before you count on it.

What's open in the park

Conditions change, so treat this as a snapshot from mid-July 2026, not a promise.

The classic first stop is the Redwood Loop Trail, an easy 0.6-mile walk through the old-growth grove near the historic park core. It's flat, family-friendly, and the best place to see fire scars and new growth side by side on trees that have been alive for well over a thousand years.

The trail network keeps growing. Friends of Santa Cruz State Parks reports that a recent round of work opened about 4 more miles of trail, restoring access to Sempervirens Falls, along with segments of the Skyline to the Sea Trail from the main day-use area to China Grade Road and beyond toward Castle Rock, plus the Hihn Hammond connector along Opal Creek. At the same time, closures still happen: State Parks currently lists Hollow Tree Trail as temporarily closed from winter storm damage. Check the current trail map on the park page before you commit to a route.

Camping is the big limitation. All campgrounds in the main park are closed, and no camping reservations are available there. State Parks also lists every backcountry trail camp in Big Basin as closed from fire damage. The coastal side, Rancho del Oso, is open for day use, with no fee or reservation needed at its Nature and History Center, and the Horse Camp there has a handful of temporary walk-in campsites by reservation plus one shared bike-in site. Check the park's page for what's bookable before you plan on staying.

Expect limited services inside the park: temporary facilities rather than the old lodge-and-store setup. Bring your own water, food, and layers.

How to visit responsibly

A recovering forest asks a little more of its visitors.

• Stay on open trails. The regrowth on either side of the tread is doing important work, and staying on the path protects both it and you.
• Respect every closure sign. They usually mark hazard trees, unstable ground, or active restoration, even when the path beyond looks fine.
• Pack out everything you bring in. Skip drones and speakers.
• Don't count on cell coverage in the basin. Download maps ahead of time and tell someone your plan.

Weather deserves respect here too. Heat, wind after storms, and winter road damage all affect this park, and this site never interprets conditions for you. Check the forecast, check the park page the morning you go, and if the park says don't come, don't come.

One more way to be responsible: support the recovery. Sempervirens Fund, the land trust that helped create the park in the first place, publishes updates and supports the ongoing restoration work.

Make Boulder Creek part of the day

The most direct route into Big Basin runs straight through downtown Boulder Creek, and the town is the natural place to bookend the trip. Fuel up, grab coffee and sandwiches, and buy anything you forgot before you head up 236, because you won't find services along the way. The Boulder Creek business directory is a good place to find gas, coffee, and a bite before the climb. On the way back down, dinner or a cold drink in town lands differently when you've spent the day in the basin.

There's more to it than a nicety. Gateway towns carry the quiet costs of a beloved park, and they felt the fire as directly as the park did. Spending your money in Boulder Creek is the most direct way a day visitor helps this corner of the Santa Cruz Mountains keep rebuilding.

Frequently Asked Questions

Do I need a reservation to visit Big Basin?

For parking, a reservation is highly recommended rather than strictly required: $6 per regular vehicle plus a $2 reservation fee, or $10 without one, per State Parks. Spaces are limited, so booking ahead through the official reservation page is the safe move. Confirm current rules on the park page before you go.

Is camping open at Big Basin?

No. All campgrounds in the main park are closed and camping reservations aren't available there, and State Parks lists Big Basin's backcountry trail camps as closed from fire damage too. Rancho del Oso, the park's coastal unit, is open for day use, with no fee or reservation at its Nature and History Center.

How far is Big Basin from Boulder Creek?

The main entrance is about 9 miles north of downtown Boulder Creek on Highway 236. The road is narrow and curvy, so plan on roughly half an hour rather than a quick hop.

Did the redwoods survive the CZU fire?

Mostly, yes. The 2020 fire affected 97 percent of the park and destroyed nearly all of its buildings, but State Parks reports that most of the old-growth redwoods survived and are regrowing. The forest looks different now, more open and sunlit, with green regrowth climbing blackened trunks.

What's the best short hike right now?

The Redwood Loop Trail, an easy 0.6-mile walk through the old-growth grove, is the reliable choice for a first visit. Longer options like the reopened stretch to Sempervirens Falls exist, but check the current trail map on the official park page, since individual trails open and close as recovery work continues.
