7 Hidden Gems in San Diego's Historic Balboa Park Beyond the Famous Zoo - The Desert Garden Trail Near Park Boulevard Reveals Ancient Cacti Collections Since 1935






Just off Park Boulevard, within Balboa Park’s extensive grounds, one can discover the Desert Garden Trail. This isn’t just a recent landscaping effort; it’s home to collections of cacti and succulents that have been cultivated since 1935. While the term ‘ancient’ might be a stretch, some of these specimens are clearly mature, representing a long-standing endeavor in public horticulture. This trail, part of the broader botanical offerings of Balboa Park, provides an opportunity to examine a diverse range of arid-adapted plants. For those who find themselves in Balboa Park beyond the usual tourist circuit of the zoo and museums, this garden offers a glimpse into a less-publicized aspect of San Diego's botanical history. It’s a place to consider the subtle adaptations of plant life in a setting known for its more prominent attractions.

Deeper within Balboa Park, beyond the predictable draw of the zoo, a different kind of attraction hums to life. Tucked away adjacent to the Spanish Village Art Center, a miniature railway operates, powered by what is reported to be the original G16 locomotive from 1948. Apparently, these engines were engineered specifically for these kinds of park railways – robust, simplified systems intended for continuous operation. To find one still in service decades later raises questions about its maintenance and original design. The scale is roughly one-eighth of standard gauge, a considerable size for a 'miniature' system. The ride itself is brief, a loop lasting just a few minutes around the Spanish Village. It’s a somewhat incongruous pairing – this functional, vintage machine operating within an arts-focused community. The steam system, I understand, is now propane-fired, an understandable modification for operational simplicity and perhaps emissions. While purists might lament the absence of coal, it’s a practical adaptation for a public park. It serves not only as a ride, but almost as a working demonstration of scaled-down rail technology from a past era of leisure engineering. For anyone with an interest in mechanics, or those seeking a quieter diversion within the park beyond the headline attractions, this miniature railway provides a curious, if short, point of exploration.


7 Hidden Gems in San Diego's Historic Balboa Park Beyond the Famous Zoo - The Palm Canyon Walkway Shows 450 Mexican Fan Palms Dating Back To 1912





Nestled away in Balboa Park, beyond the predictable crowds heading to the zoo, lies the Palm Canyon Walkway. Here, a collection of over 450 Mexican Fan Palms, apparently dating back to 1912, dominates the landscape. This isn't just a few trees scattered around; it's a dense planting, creating a shady pathway that feels surprisingly removed from the surrounding urban park. Reportedly designed by Kate Sessions, an influential figure in San Diego horticulture, the canyon is home to a range of palm varieties, not just the fan palms. Features like a wooden footbridge and a staircase are noted as adding to the visitor experience. For anyone seeking a bit of natural respite within Balboa Park that’s less advertised than its headline attractions, the Palm Canyon Walkway offers a quiet, green space to explore, a somewhat overlooked corner in a park known for grander spectacles.
Moving further into Balboa Park, away from the predictable flow of visitors, the Palm Canyon Walkway warrants a detour. Here, an assembly of approximately 450 Mexican Fan Palms marks the landscape. Dating these plantings to 1912, as the narrative suggests, raises questions of authenticity and longevity in urban botanical installations. While the claim of age is intriguing


7 Hidden Gems in San Diego's Historic Balboa Park Beyond the Famous Zoo - The Zoro Garden Butterfly Sanctuary Transforms Former 1935 Nudist Colony Site

Deeper into Balboa Park, beyond the well-trodden paths leading to the zoo, there’s a site with a rather unexpected past: the Zoro Garden Butterfly Sanctuary. It occupies grounds that were, somewhat unbelievably, a nudist colony back in the 1930s. Initially constructed for the Panama-California Exposition of 1915, this location took a sharp turn in the 1935-36 California Pacific International Exposition when it became a designated area for public nudity, of a sort. For a small fee, onlookers could observe performances by individuals clad in flesh-toned shorts. The ‘Zoro Garden’ moniker, apparently drawing inspiration from a Persian mystic and an Indiana nudist camp, adds another layer of peculiar history. Since 1997, the space has been repurposed, aiming for a more natural direction as a butterfly habitat. Today, it's presented as a sanctuary, cultivating the plant life needed for butterfly sustenance and propagation. Positioned between the Science Center and Casa de Balboa, it now offers a quiet interlude, a stark contrast to its exhibitionist origins. This shift from a stage for public nudity to a haven for insects is quite a transformation, reflecting, perhaps, changing public tastes and priorities within the park itself. For those exploring Balboa Park beyond the main attractions, Zoro Garden presents a curious point of interest, a place where nature and a rather unconventional slice of social history intersect.
Moving further into Balboa Park’s extensive acreage, away from the primary visitor paths, one discovers the Zoro Garden. Current signage describes it as a butterfly sanctuary, but its origins are rather more unconventional. Archive research reveals that this sunken garden, spanning some six acres, was originally conceived for the 1935 California Pacific International Exposition as a nudist colony. For a modest fee, visitors could observe performances within this space, though reports suggest ‘nudity’ was perhaps a theatrical interpretation rather than literal. Apparently, the concept drew inspiration from a nudist camp elsewhere and adopted a name linked to the mystic Zoroaster – a curious combination of influences.

Since the late 1990s, the site has been repurposed. Now, it functions as a butterfly sanctuary, planted with vegetation intended to support various butterfly species, both in larval and adult stages. One observes a deliberate planting strategy, seemingly designed to attract specific types of lepidoptera. The effectiveness


7 Hidden Gems in San Diego's Historic Balboa Park Beyond the Famous Zoo - The Veterans Museum Features Actual B-24 Bomber Artifacts From Local Convair Plant






Moving deeper into Balboa Park’s seemingly endless grounds, beyond the zoo and gardens, the Veterans Museum presents itself as a repository of military history, with a particular focus on local connections. One exhibit highlights artifacts sourced from the B-24 Liberator bomber, an aircraft type manufactured at the Convair plant, once a major industrial presence in San Diego. The B-24, known as the Liberator, was apparently one of the most produced American aircraft during the Second World War; some figures claim over 18,000 were made, many rolling off the assembly lines at Convair. This volume of production is noteworthy, suggesting a significant wartime industrial output from this region. These bombers were substantial machines, reportedly with wingspans exceeding 110 feet, designed to carry considerable payloads over long distances. The museum's exhibits are said to include not only pieces of the aircraft themselves, but also personal items related to local veterans who served on these machines. While the B-24 may not command the same public recognition as some other wartime aircraft, its sheer numbers and reported bomb-carrying capacity suggest a crucial, if perhaps less celebrated, role in military operations of that era. Examining artifacts tied to its local manufacture offers a different perspective on the park’s historical offerings, moving beyond the more commonly visited attractions.


7 Hidden Gems in San Diego's Historic Balboa Park Beyond the Famous Zoo - Spanish Village Art Center Houses 37 Working Artist Studios In 1935 Original Casitas

Deeper within Balboa Park's sprawling footprint, turning away from the predictable routes, one stumbles upon the Spanish Village Art Center. It's comprised of 37 distinct artist studios, all housed within what are described as original 'casitas' from 1935. Constructed as part of the California Pacific International Exposition, the architecture consciously evokes a romanticized vision of an old Spanish village. The visual effect relies heavily on brightly coloured concrete tiles and elaborate, almost theatrical, entryways.

While the claim of ‘original casitas’ is interesting – it raises questions about what extent these structures are genuinely preserved or heavily reconstructed over the decades. Nevertheless, the site functions as a workspace for a considerable number of local artists, reportedly over 200 associated artisans in total. The studios are presented as 'working' spaces, and during visiting hours, one can apparently observe artists engaged in their craft – demonstrations are advertised, and direct purchase of artwork is encouraged.

The layout centres around a large courtyard, also decked out in vibrant colours. Interactive art activities are sometimes offered, presumably to engage a broader audience. Beyond the individual studios, the centre hosts juried exhibitions and sales events, providing a platform for local artisans to showcase their work beyond their individual spaces. Open hours are limited – 11 AM to 4 PM daily, except for major holidays. This restricted access suggests perhaps a balance between artist working hours and public interaction, which is a pragmatic approach.

The overall atmosphere is undeniably designed to be 'charming' and 'whimsical', according to some descriptions, aiming to be a visually appealing destination within Balboa Park. Whether it genuinely qualifies as a ‘hidden gem’ is debatable given its location and active promotion, but it certainly offers a concentrated dose of artistic endeavour, contrasting with the more predictable attractions in the park. For travellers interested in experiencing local artistic communities within destination cities, a brief exploration of the Spanish Village Art Center could offer a curated, if somewhat stylized, glimpse into San Diego's creative scene.


7 Hidden Gems in San Diego's Historic Balboa Park Beyond the Famous Zoo - Marston House Gardens Display Native California Plants From 1905 Landscape Design





Moving deeper within Balboa Park, away from the well-trodden paths towards the zoo and museums, the Marston House Gardens offer a calmer experience. Dating back to 1905, these gardens showcase plants native to California, a deliberate choice reflecting the landscape design of the period. The layout blends elements of English Romantic and Arts and Crafts styles, resulting in a combination of structured garden areas and more natural, canyon-like settings. It’s noted that George Cooke was the original landscape designer, commissioned by George Marston, the department store owner who built the house. Now fully grown, the gardens illustrate horticultural approaches from over a century ago. For those seeking respite from the more frequented parts of Balboa Park, the Marston House Gardens present a chance to explore early California garden aesthetics and appreciate the quieter side of the park’s attractions.
Further into Balboa Park, diverging from the commonly trod paths, one encounters the Marston House Gardens. These gardens purport to exhibit native California plants, arranged according to landscape designs dating back to 1905, coinciding with the construction of the house. The premise is intriguing - a landscape intentionally crafted with indigenous flora in the early 20th century. One wonders about the design rationale of that era. Was it purely aesthetic, or were there nascent ecological considerations at play? Claims are made of a combination of formal and rustic garden styles, attempting to interpret English Romantic and Arts and Crafts movements using local plant material. This suggests an effort to adapt European garden aesthetics to the Californian environment, which is an interesting exercise in cultural and environmental translation. The gardens are touted as reaching ‘full maturity’, which in botanical terms, invites analysis of the longevity and adaptability of the chosen species. Considering the evolution of landscaping practices over the last century, assessing how faithfully the current gardens reflect the original 1905 vision would be a worthwhile inquiry. For those interested in the intersection of historical landscape design and native plant ecology, the Marston House Gardens offer a less-obvious point of investigation within Balboa Park, distinct from the more prominent attractions.
