Six years after the CZU Lightning Complex fire tore through the Santa Cruz Mountains, the redwoods at Big Basin still wear the fire on their bark. Walk the Redwood Loop Trail today and you will see thousand-year-old trunks scarred black at the base with fresh green needles pushing out above the char line. The forest is not hiding what happened to it. It is growing back in front of anyone willing to make the drive up Highway 236.
What has changed is not the visible damage. It is the money behind fixing it.
For most of the years since the fire burned through 97 percent of the park's 18,224 acres, California State Parks worked the recovery on what staff have described as a shoestring budget, patching together trail crews and conservation corps labor as funding allowed. That has shifted. The state is now fronting construction costs with the expectation of reimbursement from the Federal Emergency Management Agency, which means the pace of trail reconstruction over the past year has outrun almost everything that came before it. If you have been waiting for a single "Big Basin is back" announcement, you are waiting for the wrong signal. The real story is a funding mechanism that turned a slow trickle of reopenings into a construction schedule.
The Math Locals Should Actually Track
Before the fire, Big Basin held roughly 85 miles of trail, threading hikers and equestrians all the way to Castle Rock State Park along the eastern ridge of the range. As of this summer, field reporting from Bay Nature magazine put the open trail total at about 17 miles, a little under a quarter of what the park once offered. California State Parks' own May 2026 figures describe more than 20 miles of trail restored since the park's partial day-use reopening in July 2022, a modest difference from the Bay Nature count that likely comes down to how fire roads and connector trails get tallied. Either way, the honest read is the same: this is a park operating at roughly a fifth to a quarter of its old footprint, and every mile added back is a real event, not a rounding error.
The visitation numbers make the appetite for that recovery clear. More than 230,000 people have passed through Big Basin since the 2022 reopening, according to the state's own count, funneling through a day-use system that still requires an online parking reservation and still charges the same modest entry fee it did before the fire, six dollars per vehicle plus a two dollar reservation surcharge.
What Reopened, and When
The trail network has come back in named, dated increments rather than one broad gesture. The San Lorenzo Valley Post reported in November 2025 that crews had reconnected a stretch of the Skyline to the Sea Trail linking the Redwood Loop back to Middle Ridge Road and up to Sunset Trail, with another 3.5 miles expected before the end of that year. By this past May, State Parks confirmed the return of the Sequoia Trail, a 2.9-mile route that can be combined with a segment of Skyline to the Sea into a 4.3-mile loop out of the main day-use area, passing the 20-foot Sempervirens Falls along the way.
Earlier reopenings layered in the Meteor Trail, a one-mile stretch of Skyline to the Sea, and a mile of North Escape Road that allows dogs on leash, a detail that matters to anyone in Boulder Creek or Ben Lomond who has been waiting to bring a leashed hiking partner back into the park. The Redwood Loop itself, an easy 0.6-mile walk through old growth near the historic park core, has been open since the summer after the fire and remains the most reliable short outing for anyone who wants to stand under surviving redwoods without committing to a longer route.
Not every segment holds. The Hollow Tree Trail was listed as temporarily closed after winter storm damage earlier this year, a reminder that a route open last month can be roped off the next, whether from new construction or fresh weather damage on ground that fire already destabilized. The working rule for anyone planning a visit this fall is the same one State Parks gives: check the current trail map the morning you go, and treat every closure sign as real even when the path beyond it looks fine.
| Trail or segment | Length | Status as of 2026 |
|---|---|---|
| Redwood Loop | 0.6 miles | Open, reopened 2022 |
| Sequoia Trail to Sempervirens Falls | 2.9 miles | Reopened, connects to Skyline to the Sea |
| Skyline to the Sea (Redwood Loop to Middle Ridge Rd/Sunset Trail) | 1.2 miles | Reopened fall 2025 |
| North Escape Road | 1 mile | Open, dog-friendly |
| Meteor Trail | 1 mile | Open |
| Hollow Tree Trail | — | Temporarily closed for storm damage |
Getting There Now That Summer Is Over
The park ran a pilot shuttle this year from a temporary lot at Saddle Mountain, at the corner of Highway 236 and Little Basin Road, into the main day-use area every summer weekend and holiday from Memorial Day through Labor Day. Santa Cruz Metro paired that with weekend service on Bus Route 35, which required no entrance fee or reservation for anyone arriving by bus. Both of those programs were seasonal, and both wound down with the summer. Fall visitors are back to the standard access pattern: drive up from Boulder Creek on Highway 236, reserve parking in advance since spaces are limited and not guaranteed without a reservation, and expect no cell service near the entrance kiosk. That last point catches people every year who assume a rideshare app will get them back down the mountain. It usually cannot, since drivers frequently cannot get a signal to accept a return trip from inside the park.
The only camping currently available anywhere in the park is at Rancho del Oso, the coastal unit off Highway 1 near Davenport, where an interim walk-in and bike-in campground has reopened. Every campground closer to the historic core remains closed while the park works through its long-range facilities planning.
A Forest Rebuilding Itself Alongside the Trail Crews
Part of what makes this recovery different from a simple construction project is that the landscape itself keeps changing the work plan. Ceanothus, a fire-dependent shrub whose seeds had been waiting in the soil for decades of suppressed burns, sprouted after the fire and has grown thick enough in places that conservation corps crews spend real time clearing it just to keep trails passable. Wildlife has come back visibly enough that State Parks lists deer, raccoon, fox, coyote, and mountain lion sightings as part of the ordinary account of the park's recovery, alongside birds like acorn woodpeckers and the marbled murrelet.
None of this is happening on a fixed calendar. State Parks has said plainly that there is no set date for a full reopening, and the planning documents guiding the work, including a facilities management plan and forest management strategy, are still moving through stages of public review. What is different now is that the money to keep building trail segments is no longer the constraint it was for the first several years after the fire. The mileage will keep growing. The honest way to track that growth is trail by trail, not by waiting for an announcement that says the park is whole again, because that announcement was never going to be the shape this recovery takes.
If you are already in this stretch of the Santa Cruz Mountains, the practical move this fall is simple: check the current map the morning you go, book the parking reservation ahead of time, and treat Big Basin as a park you visit in growing sections rather than one you wait to see finished.
