Volcano Winery. 96 miles from Kailua-Kona and 1 mile from Volcano National Park. Free Wine tasting. They even offer a wine made with honey instead of grapes.......very different. Well worth the detour if your a wine drinker and in the neighborhood anyway.
Craters road in the Volcano National Park. This is an amazing road! Along the way, you'll see where a previous lava flow covered the previous road. There are great views of the different types of lava along here. At the end of the road is a ranger station. We arrived there at dusk and bought a flash light from a ranger and walked to a viewing area. As the sun set, the lava flow a couple miles away was easy to see. Do take (or buy for $3 from the ranger station) a flash light, though. It gets very dark and the viewing area is not on a path--it's over hardened rugged lava flows.
