Watching these elite athletes compete in this extraordinary event is genuinely awe-inspiring.

Visitors can indulge in gourmet food tastings, wine pairings, and culinary demonstrations while enjoying the island’s lush, tropical surroundings. It’s a fantastic way to experience Hawaii’s culinary excellence and connect with its local food scene.

The IRONMAN event and the Hawaiʻi Food & Wine Festival, two extremes of athletic endurance and culinary artistry, anchor October on the Big Island. These two marquee events can frame your visit.

If your stay includes Kona or Hilo, you'll also find smaller markets, food events, and possibly local concerts or cultural performances in evening schedules. Because of the island’s size and terrain, it’s worth picking a region (Kona, Hilo, Volcano, Kohala) as “home base” and finding events around there.

Pro tip: For IRONMAN, plan for road closures, spectator vantage points, and logistics (transport, hydration, schedule). For Food & Wine events, expect ticketed dinners/galas that sell out.
