What it is
Smith's Tropical Paradise is a 30-acre, family-owned botanical and cultural garden located within the Wailua Marina State Park on the east side of Kauaʻi. It has been operated by four generations of the Smith family since the 1940s. The garden is a standalone daytime attraction but also serves as the setting for the well-known Smith Family Garden Luau and is the departure point for their Wailua River boat tours to the Fern Grotto. The grounds feature over a mile of pathways through themed gardens (including Japanese, Filipino, and Polynesian areas), a tropical fruit orchard, bamboo forests, and lagoons.
Visitor experience
The primary activity is a self-guided stroll along flat, paved pathways, which takes approximately 45 minutes to 1.5 hours. The garden is known for its serene atmosphere, lush tropical plantings, and abundant birdlife, including numerous free-roaming peacocks. Visitors can explore replicas of traditional Filipino and Polynesian huts, a Japanese-themed garden island, and an orchard with over 20 types of tropical fruit. The experience is low-key and relaxed. For those attending the luau in the evening, arriving early allows time to explore the gardens, often with the option of a narrated tram tour.
Logistics
Location: 3-5971 Kuhio Hwy, Kapaʻa, within Wailua Marina State Park on the Coconut Coast.
Hours: The garden is open for daytime visits on weekdays (Monday through Friday) from 8:30 a.m. to 4:00 p.m., with the last entry at 3:00 p.m. The luau has a separate, seasonal evening schedule.
Cost & Reservations: Garden-only admission does not require reservations. As of early 2026, prices were $10 for adults and $5 for children (ages 3-12). The luau and river tours must be booked in advance and often sell out.
State Park Fees: As of February 15, 2026, the state charges separate per-person and per-vehicle fees for entry to the Wailua River State Park area, which are paid directly to the state via credit card upon arrival. This fee should be verified by visitors.
Parking: Free and ample parking is available on-site.
Duration: A garden visit typically lasts 45 to 90 minutes. It works well as a quick stop or a half-day activity, especially when combined with a river tour or lunch in nearby Kapaʻa.
Accessibility: The garden pathways are paved and flat, making it fully accessible for wheelchairs and strollers. A tram is offered for garden tours as part of the evening luau package.
Safety and cautions
- Unfenced Water: Ponds and lagoons throughout the garden are not fenced, requiring close supervision of young children.
- Mosquitoes: The lush environment and still water can attract mosquitoes, particularly after rainfall. Using insect repellent is recommended.
- Sun Exposure: While there are shaded areas, visitors should be prepared for tropical sun with hats, sunscreen, and water.
- Wildlife: Visitors should not feed the birds or other wildlife, except with approved food from dispensers if available.
- Operating Hours: The garden's limited weekday-only hours can be missed if not planned for. The luau operates on a different, more restricted schedule (e.g., only certain days of the week depending on the season).
Editorial take
Who should prioritize it: Smith's is ideal for families with young children, visitors with limited mobility, and multi-generational groups looking for an easy, accessible, and affordable nature walk. It's a peaceful, low-stress option for those seeking a break from beaches or strenuous hikes, and it's a convenient add-on for anyone already planning to attend the Smith's luau or take the Fern Grotto river tour.
Who should skip it: Serious horticulturalists and botanists may be disappointed by the sparse plant labeling and lack of in-depth interpretation. Travelers seeking a wild, undeveloped nature experience or a challenging hike should look elsewhere.
Not to be confused with:
- National Tropical Botanical Garden (NTBG): Specifically Allerton Garden and McBryde Garden on the South Shore. The NTBG properties are research-focused, significantly more expensive, require guided tours and advance reservations, and offer a much deeper botanical experience.
- Luau Kalamaku: Another popular luau on Kauaʻi, located at Kilohana Plantation. While both are well-regarded, Smith's is unique for its extensive garden setting and inclusion of Asian cultural dances alongside Polynesian ones.
