Stay Fit in California Without a Gym Bill: Borrow a State Parks Pass, Use LA County's Fitness Zones, and Watch the Smoke Forecast

California has mild weather in much of the state for much of the year, a huge state park system and long paved trails near its biggest cities. The cost of getting in can add up, though, and so can gym fees. Here’s how to get most of it free, and the one California hazard that should change your plans: wildfire smoke.

Borrow a state parks pass from your library

The simplest free option is at your public library. The California State Library Parks Pass is lent to library card holders and covers day-use entry for one passenger vehicle holding nine people or fewer, or one motorcycle, at more than 200 participating state park units [2].

It has limits. It doesn’t cover per-person or tour fees, camping, boat use, group sites, special events or extra vehicles, and it isn’t honored at units run by federal or local agencies or by concessionaires [2]. Ask your library how long you can keep it and whether there’s a waitlist.

State park passes, from free to $195

If you visit state parks often, one of these passes may save money.

Timing matters for the Golden Bear passes. Online applications for 2027 passes open December 1, 2026. An application sent on November 30 or earlier is for a 2026 pass, which expires at the end of this year [1].

Los Angeles County: free outdoor gyms in the parks

LA County Parks says it has 60 parks “designed for all kinds of fitness needs” and at least 31 fitness zones, outdoor equipment areas for strength and cardio. The county’s word on cost: “best of all, it’s free of charge” [3]. Its par courses, exercise stations along a path with signs that explain each move, are free as well [3].

The county also runs walking clubs and has weight rooms at some parks. Classes and weight room access vary by park, so check with yours [3]. City of Los Angeles parks are a separate system with their own programs.

Long paved trails

San Francisco Bay Trail. More than 350 miles of the Bay Trail are complete, on the way to a planned 500-mile route around San Francisco and San Pablo bays, according to the Association of Bay Area Governments [5]. The finished trail is meant to circle both bays [5], so many Bay Area residents already live near a segment.

American River Parkway, Sacramento. The Jedediah Smith Memorial Trail runs 32 miles, from Discovery Park to Beal’s Point at Folsom Lake [4]. Riding or walking in is one way to use it without a car. If you drive into a Sacramento County Regional Parks fee area, the park fee is $8 per vehicle [4].

When wildfire smoke changes your plans

In California, the air can matter as much as the temperature. During fire season, check the Air Quality Index (AQI) before any outdoor workout.

The California Air Resources Board says “people should avoid exercising outdoors during smoky conditions,” and to consider skipping outdoor activities altogether when the AQI is in the unhealthy range [7]. It also warns that wearing a mask is not a reason to spend more time active outdoors [7]. On those days, move your workout to a free indoor option, such as a park weight room, or a workout at home.

Putting a week together

The CDC says adults need 150 minutes of moderate activity a week, like brisk walking, plus muscle-strengthening activity on at least two days [8]. Vigorous activity counts about twice as fast [8]. A California version of that week could be three walks on a Bay Trail or American River segment, a weekend hike on a borrowed library pass, and two strength sessions at a county fitness zone.
