Urban botanical gardens offer peaceful escapes from city life, but admission fees can add up quickly for families and frequent visitors. Fortunately, many cities across the United States have recognized the importance of making these green spaces accessible to everyone by offering free admission days throughout the year.
Here is a list of 15 cities where you can enjoy world-class botanical gardens without spending a dime.
Washington D.C.

The U.S. Botanic Garden stands out as one of the most generous garden destinations in the country because it never charges admission. Located just three blocks from the Federal Center SW metro station, this living plant museum welcomes visitors year-round with access to outdoor gardens and the stunning Conservatory filled with tropical plants, desert species, and seasonal displays.
The garden’s permanent collection includes over 44,000 plants spanning more than 9,500 different species, making it one of the most diverse free botanical experiences available anywhere in the United States.
Seattle

Washington Park Arboretum proves that exceptional botanical experiences don’t have to come with a price tag. This 230-acre wonderland on the shores of Lake Washington is completely free to explore every single day from dawn to dusk.
The arboretum features more than 40,000 plants including internationally renowned collections of oaks, conifers, camellias, and Japanese maples. The only exception is the Seattle Japanese Garden located within the arboretum, which does charge admission.
Athens, Georgia

The State Botanical Garden of Georgia at the University of Georgia welcomes visitors with both free admission and free parking across its 323 acres. Located about 70 miles east of Atlanta, this hidden gem offers themed gardens, miles of walking trails, and a visitor center open Tuesday through Sunday.
The garden combines natural wooded areas with cultivated displays, creating an educational experience that’s accessible to everyone without any financial barriers.
Philadelphia

Awbury Arboretum has been free and open to the public for over a century. This 56-acre oasis in the historic Germantown neighborhood features woods, meadows, gardens, wetlands, and agricultural fields that visitors can explore from dawn to dusk every single day of the year.
Once the estate of a prominent Quaker family, Awbury now serves the community with AdventureWoods, the Farm at Awbury, and numerous educational programs alongside its preserved trees and gardens.
Cleveland

Rockefeller Park Greenhouse stands as Cleveland’s gift to garden lovers everywhere. This city-owned botanical garden opens its doors seven days a week, including weekends and holidays, without ever charging admission.
The four-acre property features both indoor greenhouse displays with tropical plants, fruit trees, and orchids, plus outdoor specialty gardens that bloom throughout their growing seasons. Free parking makes this already generous offer even better for visitors.
New York City

The New York Botanical Garden in the Bronx offers free grounds admission every Wednesday for New York City residents all day long. Non-residents can also enjoy free admission on Wednesdays between 10 and 11 a.m.
This 250-acre National Historic Landmark features 50 distinct gardens and plant collections, including an old-growth forest that represents the last remnants of the woodland that once covered New York City. Visitors need to show proof of NYC residency to take advantage of the full-day free admission.
San Francisco

San Francisco Botanical Garden makes nature accessible through multiple free admission opportunities. Every single day, the garden opens free to all visitors from 7:30 to 9 a.m., giving early risers a chance to explore 55 acres of specialty gardens in peaceful morning light.

Denver

Denver Botanic Gardens offers multiple free admission days spread throughout the year for visitors who want to explore its York Street and Chatfield Farms locations. The garden releases free day tickets three months at a time on a rolling basis, with tickets becoming available on the first of each month.
Past free days have included Martin Luther King Jr. Day, Earth Day, and the day after Thanksgiving, among others. Advance reservations are required for these popular free days.
Chicago

Chicago Botanic Garden in Glencoe demonstrates exceptional commitment to accessibility by offering 52 free admission days each year for Illinois residents. These free days are distributed throughout all four seasons and include several school holidays, making it easier for families to visit.
Preregistration is required for non-members, and visitors can reserve tickets up to two months in advance. Parking fees still apply on free admission days, but the saved admission cost makes this 385-acre garden much more accessible.
Queens

Queens Botanical Garden provides two weekly opportunities for free admission. Every Wednesday from 3 to 6 p.m. and every Sunday from 9 to 11 a.m., visitors can explore the gardens without paying the usual admission fee.
These regularly scheduled free hours make it convenient for local residents to incorporate garden visits into their weekly routines. The garden may suspend free hours during special events, so checking the calendar before visiting is always smart.
Brooklyn

Brooklyn Botanic Garden offers the most generous free access during the winter months from December through February, when admission becomes pay-what-you-wish on weekdays. This winter pricing helps the garden stay accessible during a season when many people want to escape into the warmth of the Conservatory.
Additionally, the garden participates in several community access programs that provide free admission to specific groups throughout the year, including military families and library cardholders through the Culture Pass program.
Phoenix

Desert Botanical Garden celebrates the stunning flora of the Sonoran Desert while offering free admission on the second Tuesday of every month. This means twelve opportunities each year to explore five different trails without paying the usual $40 adult admission fee.
The garden also participates in the local Culture Pass program through public libraries, which provides additional free admission opportunities for library cardholders who can check out passes good for two people.
Los Angeles

The Los Angeles County Arboretum and Botanic Garden in Arcadia opens free to the public on the third Tuesday of each month. This 127-acre garden features plants from around the world, historic buildings, and peacocks roaming the grounds.
Advanced reservations are required for these monthly free days. The arboretum also offers free admission to EBT cardholders and their families at any time, making the garden accessible to those receiving food assistance benefits.
Portland

Leach Botanical Garden in southeast Portland takes a refreshingly straightforward approach with its Garden for All program, which provides free admission to anyone who requests it. Visitors don’t need to prove enrollment in any assistance program or meet specific requirements—they simply walk up to the Visitor Services desk and request Garden for All tickets.
This dignified approach to accessibility removes barriers while respecting visitor privacy. The garden issued over 1,350 Garden for All tickets in 2023 alone.
Fort Worth

Fort Worth Botanic Garden offers multiple free admission days throughout the year as part of its commitment to making this 120-acre sanctuary accessible to everyone. The garden doesn’t require tickets for free days—visitors simply arrive during regular hours.
In addition to quarterly free admission days, the garden provides free access to veterans year-round, active military families during summer months, and Fort Worth ISD students during specific afternoon hours on school days.
A Garden For Everyone

These cities prove that exceptional botanical experiences shouldn’t be reserved only for those who can afford admission fees. From the completely free year-round access at the U.S. Botanic Garden and Washington Park Arboretum to the regular monthly free days in Phoenix and Los Angeles, these programs ensure that everyone can benefit from time spent among plants and gardens.
The variety of approaches—from specific free days to always-free admission to request-based programs—shows that there’s no single right way to make gardens accessible, just a shared commitment to opening green spaces to entire communities.
