Hilo is the warm, welcoming version of Hawaiian towns, which are normally keen on exploiting the tourism trade. Wailoa State Park is not far from the lazy downtown district, offering various outdoor activities.
The ocean is also nearby, drawing the most visitors daily. The more urban settings are basically used for breaks from the glorious oceanfront. Surrounding Hilo are beautiful hills and waterfalls, accessible from paths that flow through downtown.
Whether you are looking for a starting point for an outdoor adventure or a cozy atmosphere in which to wind down, vacationing in Hilo is definitely a good idea.
