What does the extra five dollars at the Jack London State Historic Park gate actually buy? On June 1, 2026, the vehicle entrance fee went from $10 to $15. It covers a car and up to nine passengers, and it was the first increase since 2012, when the fee moved from $8 to $10. The fee still covers the House of Happy Walls Museum, the historic cottage, Beauty Ranch, the historic orchard and more than 30 miles of trail. The official explanation for the increase points somewhere most visitors never drive, the old institutional land in Eldridge.
That is the real Glen Ellen story this fall. The village's public ground is growing east, and it is opening on foot, one guided walk at a time. The Village Fair on Arnold Drive and the autumn calendar at the park both sit at the edges of that change.
The Five Dollars at the Gate
The joint announcement from California State Parks and Jack London Park Partners quoted Maria Mowery, Bay Area Superintendent II, on why the fee went up:
"While fee increases are always a last resort, this adjustment—the first in 14 years—is necessary to support ongoing trail maintenance, resource protection, and the expansion of parklands like the recently transferred open space from the Sonoma Developmental Center."
That sentence connects two places that feel separate on a map. Jack London Park Partners has run the historic park since 2012. The former Sonoma Developmental Center open space is a different property under State Parks' interim management. State Parks says the long-term plan is to fold that open space into Jack London State Historic Park through a public General Plan Amendment. So today's gate fee partly funds the park as it is expected to be.
The increase only applies to drivers. Entry on foot or by bicycle is still free. For anyone within walking or riding distance of London Ranch Road, the higher fee doesn't change how they get in.
Ground That Opens One Walk at a Time
The transfer itself is not new. State Parks announced in January 2024 that it had taken jurisdiction over roughly 650 acres of SDC open space. In June 2024 it announced the last piece, the 11.4-acre Camp Via parcel. At the time, the agency described the land as a connection from Jack London State Historic Park to the neighboring regional park. The 2026 change is that the land is now being programmed for visitors.
State Parks' July 2026 newsletter for the SDC open space split its guided hikes into two programs and said both would continue after July.
The Sunrise/Baker loop is the ADA-accessible guided hike. It is flat and takes 45 to 50 minutes, with light shade, around the easternmost part of the property. The route passes what is left of SDC's working past, including the farm, a horse corral, the dairy, maintenance buildings, the old sewage treatment plant and the soccer field. It circles a seasonal wetland ringed by oaks and pines. That eastern side once handled the animal husbandry and facility work that made the center largely self-sufficient for a time.
The Lake Suttonfield loop is about 2.5 miles, unpaved, with small elevation changes. State Parks' interpreters call the historic man-made reservoir "a beloved hiking destination for Glen Ellen locals." Their notes mention freshwater birds, woodpeckers and birds of prey along the way.
State Parks walks have met at the corner of Harney and Railroad in Eldridge. That is also where September's BioBlitz started before it climbed to the peak above Lake Suttonfield. From May 27 to June 4, State Parks and Cal Fire graded the fire roads around Suttonfield Lake, which connect Sunrise Road, Sonoma Valley Regional Park and the Cal Fire station, for patrol and maintenance access.
The rules differ from what regulars at the county park may expect:
- Dogs are allowed on paved roads but not on trails.
- No swimming or fishing is allowed in Suttonfield Lake or Fern Lake.
- Both lakes are still owned by the local water district, not State Parks.
Several things are still unsettled. In July, State Parks staff were still choosing themes, locations and accessibility features for interpretive panels, so new signs shouldn't be assumed. The June newsletter asked the public for accessibility suggestions, and the July newsletter presented the accessible hike as an introduction to and celebration of disability history and access. Regular daily hours and dedicated public parking for the SDC open space haven't been published in State Parks' recent materials. The guided walks remain the clearest way in.
Down the Hill, a 300-Yard Parade
Glen Ellen's public ground is at its smallest on Sunday, October 11. That morning Arnold Drive closes for the Glen Ellen Village Fair. The Sonoma Index-Tribune counts it as the 34th year, and one events calendar lists it as the 35th annual. The road closes at 9:30 a.m. and reopens at 6 p.m., and the parade starts at noon. It runs from Warm Springs Road to London Ranch Road, about 300 yards through a right-hand chicane and over a concrete T-beam bridge built in 1939.
On the portable stage outside the U.S. Post Office, The Groove Incident, a Sonoma band playing '70s and '80s hits, starts at 12:30 p.m. The Rhonda Linstadt Band follows at 3 p.m. with Linda Ronstadt songs plus Emmylou Harris, Eagles and Jackson Browne covers. Just up from the post office, the Youthful Performance Stage features students from the Santa Rosa School of Rock and the Cannon School of Music, some performing in public for the first time.
The parade ends where the route up to the park begins. London Ranch Road climbs from the fair's finish line to the gate where the new fee is collected. The day before, Saturday, October 10, the park holds its final WILD Trail Challenge hike, which was moved from an earlier date because of heat. That puts the season's last organized trail outing and the village's one car-free afternoon on the same weekend.
The Museum Carries the Season Into November
The park's October program runs past Halloween because of what is inside the House of Happy Walls. From October 4 to November 6, the museum is showing two ofrendas for Día de Muertos, which is traditionally observed November 1 and 2. The Legacy Ofrenda honors Jack London, Charmian London and others tied to the property. It uses photographs, reproductions and symbolic objects to reflect the couple's partnership, their writing and travels, and their life at Beauty Ranch. The second, the Community Ofrenda, is a shared, participatory offering where visitors, locals and volunteers can add a small photograph, a written name, a memory, a drawing or a message.
The calendar also stretches beyond English and beyond daylight. Spanish-language wildlife walks at dusk run on October 23 and 30, and a family fall-color event fills October 25. The Fall 2026 Moonletter already listed a Spanish-language program in September, Entre Bosques y Lagos, "Between Forests and Lakes." That title fits a park that is expected to take in Lake Suttonfield's watershed.
Some of that funding comes from the village itself. Glen Ellen Village Market's fourth annual Dine and Donate dinner on May 29, 2026, drew 122 people and raised a record $6,100 for Jack London Park Partners, the nonprofit that funds and runs the park. The market is about four minutes away.
October and Early November, Uphill and Down

For a stop in the village between any of these, Wolves Lovers + Thieves has been pouring sparkling wine at 13647 Arnold Drive, Unit 2, since December 2025. Lindsey Blanchard and Ryan Kuhlmann opened it. The Index-Tribune listed its hours in April as noon to 5 p.m., Wednesday through Sunday, so it may be worth checking before you go.
The guided Sunrise/Baker and Lake Suttonfield programs aren't tied to a single date on this calendar. State Parks said both would keep running after July, and its SDC open space page and newsletters are the place to find the next meeting time at Harney and Railroad.
Land next to protected open space is one of the quieter factors in what a Glen Ellen property is worth, and the SDC lands are slowly becoming that kind of neighbor. Caroline Sebastiani follows these changes parcel by parcel. For a private view of where your property stands this fall, request a free home valuation.
