This Saturday afternoon, if you walk behind the Mill Valley Public Library and settle onto the amphitheater lawn with a blanket and a bottle of something cold, you will watch a free show. No ticket, no will-call line, just a donation bucket near the entrance and one of Shakespeare's less-frequently performed comedies, written more than four centuries ago, playing out under the redwoods. Four weeks later, on that same patch of grass, admission runs $25 at the gate, or $20 if you buy early, and the lineup includes 135 juried artists instead of five actors in doublets.
That is not a coincidence of scheduling. It is a real shift in how Old Mill Park operates, and if you live in Mill Valley you are close enough to feel both halves of it without ever getting in a car. The park spends late August running on a scrappy, donation-funded community theater model. Then, almost overnight, it flips to a ticketed regional institution with a 69-year track record. Knowing exactly when that handoff happens, and where the two calendars briefly overlap on a single Saturday, is the kind of detail that only shows up if you are actually watching the park instead of just walking past it.
The Last Free Weekends Behind the Library
The Curtain Theatre has been staging free Shakespeare in Old Mill Park for 26 years, and this season's production, Love's Labour's Lost, is in its final stretch. Performances run Saturdays and Sundays at 2 p.m. at the Old Mill Park Amphitheater, 352 Throckmorton Avenue, with the run closing on Labor Day Monday, September 7. As of this weekend, that leaves the August 22 and 23 shows, the August 29 and 30 weekend, and the final September 5, 6, and 7 dates before the amphitheater goes dark for the season.
The company is working under new leadership this year, and the production itself leans into that fresh footing: director Doyle Ott has staged the play with live acoustic music from longtime Curtain Theatre collaborator Don Clark and set design by Steve Coleman, another company veteran. The cast includes Euan Ashley as the King of Navarre and D.G. Hardy as the sharp-tongued Berowne, opposite Alexandra Fry as the Princess of France. None of that costs anything to watch. The company operates on donations, and the standard advice from anyone who has been before still holds: bring a picnic, claim your patch of lawn early, and plan for a two-hour run time with an intermission.
That last detail matters more than it sounds like it should, because it sets up the one Saturday in September where the park's two calendars actually cross paths.
Five Weekends, Two Very Different Price Tags
Here is the full sequence, side by side, so the shift is easy to see:
| Event | Dates | Location | Cost | Format |
|---|---|---|---|---|
| Love's Labour's Lost (The Curtain Theatre) | Aug 22–23, Aug 29–30, Sept 5–7 | Old Mill Park Amphitheater | Free, donations accepted | Outdoor theater, bring your own seating |
| Mill Valley Western Beer & Wine Festival | Sept 5, 4–7 p.m. | Downtown Mill Valley | Tasting admission | Street festival |
| Mill Valley Fall Arts Festival (69th annual) | Sept 19–20, 10 a.m.–5 p.m. | Old Mill Park | $20 early bird through Sept 1, $25 after and at the gate; seniors $15/$20; free for children, students, and teachers | Juried art fair with live music |
| Concerts in the Plaza | Sept 26, 11 a.m.–7:30 p.m. | Mill Valley Downtown Plaza | Community event | Live music and dancing |
Read across that table and the pattern is obvious once someone points it out. The park's free window is short, it is closing right now, and the paid programming that replaces it does not just cost more, it moves to a different part of town entirely by the time you get to Concerts in the Plaza, which trades the redwood canopy for the open downtown plaza.
The One Saturday Where Both Calendars Collide
September 5 is the day to circle if you only pay attention to one date this fall. It is one of the final performance days for Love's Labour's Lost, and with a 2 p.m. curtain and a two-hour run time, the show wraps up right around 4 p.m. That is almost exactly when the Western Beer & Wine Festival opens downtown, running from 4 to 7 p.m. the same evening.
Nobody is coordinating those two events on purpose. The Curtain Theatre has held its Saturday and Sunday 2 p.m. slot for 26 seasons, and the Chamber sets its own festival calendar independently. But the practical result is that a resident can watch one of the last free Shakespeare performances of the year and then walk into a ticketed downtown festival on the same afternoon, without needing to plan around a single conflict. That kind of overlap will not repeat in exactly this form once the play closes on Labor Day, which makes September 5 the one date this month where Mill Valley's free and paid calendars genuinely share a day.
Why the Same Lawn Comes With a Ticket Price a Month Later
The jump from a donation jar to a general-admission ticket, $20 if you buy before September 1 and $25 at the gate after that, is not arbitrary, and it says something real about the difference between the two organizations running the park this fall. The Curtain Theatre is a volunteer-driven nonprofit staging one production a year with a small cast and a set built by the same company members season after season. The Mill Valley Fall Arts Festival is entering its 69th year with 135 juried artists, multiple live music acts across two days, and, new for 2026, a curated wine tasting package featuring Northern California wineries. That is a fundamentally larger logistical footprint, and the ticket price reflects the cost of vetting and hosting that many working artists rather than a markup on the same experience.
It also explains why the festival can afford things the free run cannot: a full weekend of programmed music starting with Mill Valley's own Spencer Krenz Bluegrass Band at noon on Saturday, followed by singer-songwriter Meggy Travers and banjo player Tim Weed, plus a poster commission this year from local artist Hilary Williams. None of that is a criticism of either event. It is simply two different funding models sharing one park, a month apart, and knowing which model you are walking into changes what you should expect to pay at the gate.
A Resident's September, Mapped
If you want to actually use this calendar instead of just reading about it, here is how the next five weeks lay out:
- August 22–23 — Catch Love's Labour's Lost this weekend while it is still free. Two performance windows remain after this one.
- August 29–30 — The penultimate weekend for the play. Bring a chair if the lawn fills up.
- September 5 — The double-header day. Shakespeare at 2 p.m., Western Beer & Wine Festival downtown from 4 to 7 p.m.
- September 6–7 — The run closes with a Sunday show and a Labor Day Monday matinee.
- September 19–20 — The park changes hands. The 69th annual Fall Arts Festival takes over the same lawn, this time with a ticket booth.
- September 26 — Concerts in the Plaza closes out the stretch downtown, a different footprint entirely from the redwood setting of the earlier weekends.
Laid out this way, the six weeks stop looking like a random string of listings and start looking like what they actually are: one park and one downtown corridor cycling through three distinct identities in a single month, each with its own cost structure and its own crowd.
That kind of layered, walkable calendar is part of what makes a town feel lived-in rather than just visited, and it is the same texture that shows up in conversations with clients who already call Mill Valley home.
