How big is Anza-Borrego Desert State Park?

More than 600,000 acres, or roughly 1,000 square miles. It is the largest state park in California and the third largest in the United States, spanning parts of San Diego, Riverside and Imperial counties.

How much does it cost to enter Anza-Borrego?

Day use is $10 per vehicle, collected at the Visitor Center, developed campgrounds and several popular trailheads including The Slot and Hellhole Canyon. The park has no entrance gates and much of it can be accessed without a fee.

When is wildflower season at Anza-Borrego?

Annual wildflowers can appear from January through mid-April, with peak bloom most often between late February and early April. Timing varies year to year based on rainfall and temperature.

Is Anza-Borrego a Dark Sky Park?

Yes. The park was designated an International Dark Sky Park in 2018 at Silver tier. Borrego Springs, the town at its center, has been an International Dark Sky Community since 2009, the first in California.

Do I need four-wheel drive at Anza-Borrego?

Not for the paved roads, the Visitor Center or the main campgrounds. The vast majority of the park's roughly 500 miles of dirt roads do require a high-clearance four-wheel-drive vehicle.

Is Anza-Borrego Desert State Park open at night?

Yes, the park is open 24 hours a day, year-round. The Visitor Center is open daily 9am to 5pm October through May, and weekends and holidays only June through September.

ABF opposes new powerlink through Anza-Borrego Desert State Park.

(Borrego Springs) – “California’s largest state park — and one of the last true wild places in Southern California — could face one of the biggest industrial threats in its history,” states a website set up by the Anza-Borrego Foundation at https://theabf.org/park-threat/ . “A proposed 500-kV transmission line, the Golden Pacific Powerlink, could cut through Anza-Borrego Desert State Park— impacting wilderness, wildlife habitat, scenic landscapes, dark skies, and cultural resources.”

SDG&E released a proposed route map on April 13, 2026 and is accepting stakeholder feedback through early November 2026. You can learn more about what’s at stake, and how you can help defend the park, at the ABF’s site. Below are details.

As ECM previously reported, including an interview with SDG&E’s manager for the project, the California Independent Systems Operator (CAISO) has identified the high-voltage line as necessary to meet the state’s future electrical needs. The line would begin at the Imperial County substation and end at a new substation to be built in Orange County. SDG&E’s proposed route would cut through the heart of California’s largest state park before traveling northeast along State Route 79 in the Warner Springs and Santa Ysabel areas, then into Riverside and Orange Counties.

A 500 kV line is the highest-voltage class of transmission infrastructure built in California. The towers required to carry these lines can stand 150 to 200 feet tall, the height of a 15- to 20-story building with a cleared right-of-way stretching hundreds of feet wide.

According to the ABF, “For context, the only existing transmission line within the Park today is a 69 kV line on modest wooden poles, barely visible against the landscape. That line was constructed before the Park was established in 1933 and before the California Environmental Quality Act (CEQA) existed (1970) — it would not be permitted today.”

The cost of the line is an estimated $2.3 billion.

Strong opposition to another SDG&E high voltage line, Sunrise Powerlink, led to rerouting of that line, which was also originally proposed to go through the state park.

What you can do

The ABF’s website recommends several actions for those concerned about the proposed route at https://theabf.org/take-action/

Right Now: Stakeholder Feedback Period (Through Early November 2026)

Your participation now helps ensure stakeholders who care about the Park are part of the conversation before the project is formally submitted.

Make a Donation: This work is costly and ABF needs your support to ensure we can continue to engage.

Attend an In-Person Open House: SDG&E will hold in-person community meetings later in 2026. Specific dates and locations will be announced. Show up and ask questions about impacts to the Park. Sign up here for updates

Submit Stakeholder Feedback to SDG&E: Email the project team at GoldenPacific@sdge.com to share your input on the proposed route and raise questions about project impacts and the clean energy commitment (download letter template here).

Spread the Word: Share this page. Talk to your friends, family, and community. The more people who understand what is being proposed, the more informed the process becomes. Download our “Not Through Our Park” graphics to share and use on your social media profile.

After the CPUC Application Is Filed (Expected Fall/Winter 2026)

Once SDG&E submits its application, the project enters formal regulatory review. This is when the rigorous environmental and public review process begins under CEQA and NEPA, with multiple opportunities for public participation.

Submit Written Comments to the CPUC: Email the CPUC at public.advisor@cpuc.ca.gov or use the online Docket Card to submit your comments on the record. We will keep you informed when and how to do this when the time comes.

Rotary Sets Feb. 6 for Annual Fundraiser: A Roaring Twenties Speakeasy

By Andrea McKenna • September 10, 2026

Borrego Springs Rotary will bring the Roaring Twenties to La Casa del Zorro for its annual community fundraiser on Saturday, Feb. 6, 2027. Each February, the greater Rotary family gathers for one of its most important fundraisers of the year, raising funds to support programs and projects that benefit the Borrego Springs community. Last year’s Mardi Gras celebration drew 110 supporters for an evening of food, fun, raffles and auctions. Their generosity helped Rotary fund 30 student scholarships, send local students to leadership development programs, provide a Christmas toy for every child in Borrego Springs, and award 18 community grants. This season, Rotary is trading Mardi Gras for the glamour of the Roaring Twenties. The 2027 Rotary Annual Fundraiser Dinner will be held Saturday, Feb. 6, at La Casa del Zorro, with a Roaring Twenties Speakeasy theme, complete with Prohibition-era cocktails and period-inspired cuisine. Guests are encouraged to “throw on your glad rags” and join Rotary for what organizers promise will be a festive evening — all in support of programs that directly benefit the community. Save the date: Saturday, Feb. 6, 2027. Additional details, including ticket information, will be announced as the event approaches.
