Most coverage of AB 618 treats it like a gentle policy update. It isn’t. California just rewired the incentive structure for campsite reservations in a way that will cost real money and, for some repeat offenders, lock them out of the system entirely. If you’re planning a summer trip to Pfeiffer Big Sur, Jedediah Smith, or any of the 15,000 campsites and lodging options managed by California State Parks, you need to understand the new rules before you book a single night.

The law, authored by Assemblymember Rebecca Bauer-Kahan and signed by Gov. Gavin Newsom, took effect July 1, 2026. It applies to all reservations with arrival dates on or after that date. No grace period, no soft launch.

What the Penalties Actually Look Like

The no-show penalty is the sharpest edge here. Miss your arrival date without canceling, and you forfeit every dollar paid for the entire stay. That includes site fees, reservation fees, all of it. Gone.

Cancel within 48 hours of check-in? Same result. Full forfeiture.

Cancel 2 to 6 days out? You lose the first night’s site fee plus all reservation fees. That’s not a slap on the wrist. A peak-season site at Kirk Creek or Kirby Cove can run $35 to $65 per night. Add the reservation fees and a last-minute change of plans has a real dollar cost attached.

Cancellation timingWhat you lose
7+ days before arrivalReservation fees only (standard policy)
2–6 days before arrivalFirst night’s site fee + all reservation fees
Within 48 hours of check-inEntire stay: site fees + reservation fees
No-showEntire stay: site fees + reservation fees

Three no-shows in a calendar year triggers a 365-day ban from making any new ReserveCalifornia reservations. Three strikes. One year locked out. As Hoodline reported in July 2026, this is a hard system-wide ban, not a park-by-park restriction.

The scale of the problem is worth understanding. The San Francisco Chronicle reported over 1.4 million campsite bookings in 2023 alone. With that volume, even a modest no-show rate translates to thousands of empty sites per season at parks where waitlists stretch for months. Speculative booking, where someone grabs sites at multiple parks for the same weekend and cancels the losers at the last minute, has been a real and documented problem.

According to the California State Parks FAQ on the new policy, AB 618 is specifically designed to free up inventory at high-demand parks during peak season. The Save the Redwoods League broke this down clearly when the bill was still moving through the legislature, noting that parks like Humboldt Redwoods and Prairie Creek consistently lose usable nights to late cancellations and ghost reservations.

This isn’t bureaucratic overreach. The parks have a real inventory problem and the old penalty structure, which was essentially a small reservation fee forfeiture, didn’t change behavior.

The Lottery System and the 7-Night Cap

Two other pieces of AB 618 matter a lot for full-timers specifically.

Peak-season bookings are now capped at 7 consecutive nights per reservation. If you’re used to locking down two weeks at one spot in July or August, that’s over. You’ll need to rebook for a second stretch, which isn’t guaranteed, especially at high-demand parks.

The pilot lottery system covers up to five of the most in-demand park units. Which five parks end up in the lottery pilot and exactly how it runs is still being finalized as of this writing, but the intent is clear: replace the current system where fast internet connections and alarm clocks at booking-window-open time determine winners. A lottery won’t fix everything, but it’s a fairer shot than the current speed-booking arms race.

For RVers, the 7-night cap also intersects with the no-show penalty in an uncomfortable way. If you book a peak 7-night stay and something mechanical goes sideways on day 5 of your drive up, a last-minute cancellation now costs you the full reservation. That’s a real scenario. Factor it into your risk calculation.

How to Actually Protect Yourself Under the New Rules

Don’t book sites you’re not committed to. That sounds obvious, but a lot of campers have treated ReserveCalifornia like a hedging system. That habit is now expensive.

Set a calendar alert for 7 days before arrival. If your plans have any uncertainty at that point, cancel then and lose only reservation fees. Wait until 6 days out and the cost structure jumps sharply.

If you’re doing a longer California run, string consecutive 7-night reservations at different parks rather than trying to hold a single site. That’s more logistical work, but it’s how the system works now.

Consider the lottery parks as potential itinerary anchors. Once the pilot details are confirmed by California State Parks, those lottery results will come out ahead of the general booking window. Win a lottery slot and build your route around it. Lose and adjust. Either way, it’s better information earlier.

Camper FAQs has a solid breakdown of the new policy’s mechanics if you want to verify specific fee scenarios before booking. Worth bookmarking.

The Bigger Shift

California runs the largest state park system in the country by most measures, and what it does tends to spread. Oregon and Washington have both been watching California’s campsite ghost-booking problem closely. If AB 618 produces measurable improvements in site availability at Big Sur or the redwoods, expect similar legislation to appear in other western states within a few years.

For now, the immediate reality is simple: California campsite reservations just got higher stakes. Book what you’ll actually use, cancel early if plans change, and don’t count on leniency from a system that’s been redesigned specifically to eliminate it. The parks are worth the planning discipline. They just require more of it now.
