Is Big Basin Open? What's Accessible in 2026

The short version

• Yes, but only for limited day use. Big Basin Redwoods State Park is open 8 a.m. to sunset while it keeps recovering from the 2020 CZU fire. A lot of it is still closed.
• Parking: a reservation is strongly encouraged but not required. State Parks lists $6 per regular vehicle plus a $2 reservation fee, or $10 if you show up without one. Arrive on foot, bike, or bus and there's no fee or reservation at all.
• Camping is closed. Every campground in the main park, and every backcountry trail camp, is closed from fire damage.
• Bring your own water. There's no potable water on site, only pre-filled bottles for sale. Pack food and layers too.
• Check before you go. Access changes month to month, so the official Big Basin Redwoods State Park page is the source of truth. Nothing on this page guarantees a given trail, road, or lot will be open the day you visit.

You've got a free day and you want to stand under the big redwoods. Before you drive up, know this: Big Basin reopened, but it didn't reopen as the park in the old postcards. Knowing what "open" actually means right now is the difference between a good outing and a locked gate.

Details here follow official State Parks sources as of July 18, 2026. Because conditions shift, confirm the specifics on the official park page the morning you head out.

What's open in 2026

For 2026, the park is running its now-familiar recovery pattern: open for limited day use from 8 a.m. to sunset, with a paid parking reservation strongly encouraged and the main campgrounds still closed.

On summer weekends, from Memorial Day weekend through Labor Day weekend, State Parks has run a free shuttle from a temporary parking area at Saddle Mountain, and Santa Cruz METRO has offered weekend summer bus service to the park. Both are seasonal, and both can change, so confirm each is running before you count on it.

What's open beyond that keeps shifting as crews clear more trails and roads. A snapshot goes stale fast, so check the current park page and its map the morning you head up.

What "limited day use" actually means

This is the part that trips people up. Big Basin reopened, but it did not reopen as the park in the old postcards. Here's the shape of it.

Hours. Day use runs 8 a.m. to sunset. There's no overnight access in the main park.

Parking and fees. State Parks lists regular-sized autos at $6 plus a $2 reservation fee, or $10 per vehicle if you show up without a reservation. Spaces are limited, so a reservation is highly recommended, though not strictly required. Reservations run through the Friends of Santa Cruz State Parks system at thatsmypark.org, and the passenger-vehicle form is separate from disabled parking and bus or trailer parking. Oversized vehicles and trailers can't be accommodated for day-use parking right now, so leave the RV behind.

Arriving car-free is free. Come by foot, bike, or bus and State Parks says no fee or reservation is required. On a busy weekend, it's the cheapest and least stressful way in.

Camping. 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, so there's no walk-in or bike-in overnight option in the main park. The park's coastal side, Rancho del Oso, is open for day use, with no fee or reservation needed at its Nature and History Center, and its Horse Camp currently has a few temporary walk-in sites by reservation plus one shared bike-in site.

Water and services. Bring your own water. The park's reservation page says there's no potable water in the park, only pre-filled reusable bottles available to purchase. Facilities are temporary, not the old lodge-and-store setup, so pack food, layers, and anything else you'll need for the day.

What's open to hike, and what isn't

Treat any trail list as a snapshot, not a promise. The reliable short walk is the Redwood Loop Trail, an easy 0.6-mile loop through old-growth redwoods near the historic park core, where you can see fire scars and bright new growth on the same thousand-year-old trees. The trail network has been growing in phases as crews clear and reopen more mileage, and State Parks adds trails and backcountry roads "as they are cleared and made safe."

Closures come and go, too. State Parks lists the Hollow Tree Trail as temporarily closed after winter storm damage, a good example of why a trail that was open last month can be roped off today.

Before you commit to a route, pull up the current trail map on the park page and respect every closure sign you pass. They usually mark hazard trees, unstable ground, or active restoration, even when the path beyond looks fine.

Getting there from Boulder Creek

Downtown Boulder Creek is the gateway. From the middle of town, turn onto Highway 236, the Big Basin Highway, and follow it about 9 miles to the main entrance.

Every road into the park is narrow and curvy, and lower 236 is slow going, so give yourself close to half an hour, watch for cyclists, and use the turnouts to let faster traffic by. There are no services along 236, so fuel up, grab water and food, and buy anything you forgot in Boulder Creek before you climb.

Cell coverage in the basin is unreliable, so download your map ahead of time and tell someone your plan. For live road conditions on the way up, our Mountain Status page pulls the official sources together in one place.

Why it's still like this

Big Basin became California's first state park in 1902, and for well over a century Boulder Creek has been its front door. In August 2020, the CZU Lightning Complex fire tore through the park and burned the great majority of it, destroying nearly every building, including the historic headquarters.

Most of the old-growth redwoods survived, and State Parks reports vigorous new growth and returning wildlife, but rebuilding roads, water systems, and safe trails across a fire-scarred park is slow, years-long work. That's why access opens in careful phases, and why the answer to "is it open" is a real but qualified yes.

Frequently asked questions

Is Big Basin open right now?

It's open for limited day use, 8 a.m. to sunset, as it recovers from the 2020 fire, with much of the park still closed. Conditions change often, so confirm on the official Big Basin Redwoods State Park page before you drive up. Nothing here guarantees a given trail or lot will be open.

Do I need a parking reservation?

A reservation is highly recommended but not strictly required. State Parks lists $6 per regular vehicle plus a $2 reservation fee, or $10 without one, and spaces are limited enough that a busy weekend without a reservation is a gamble. Book through the Friends of Santa Cruz State Parks reservation system, and confirm current pricing on the park page.

Can I get in without paying for parking?

Yes. State Parks says there's no fee or reservation for visitors arriving on foot, by bike, or by bus. On summer weekends there's also been a free shuttle from Saddle Mountain and weekend METRO bus service, both seasonal, so check that they're running first.

Is camping open at Big Basin?

Not in the main park. Its campgrounds are closed, no reservations are available there, and State Parks lists every backcountry trail camp in Big Basin as closed from fire damage. The one exception is on the coastal side: the Rancho del Oso Horse Camp has a handful of temporary walk-in campsites by reservation plus one shared bike-in site. Rancho del Oso is also 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 up Highway 236 from downtown Boulder Creek. The road is narrow and winding, so plan on roughly half an hour, not a quick hop, and fuel up in town first.

Is there water and food in the park?

Bring your own. The park's reservation page says there's no potable water in the park, only pre-filled reusable bottles for sale, and services are limited and temporary. Pack water, food, and layers.
