Ka'u Desert Trail via Hawaii Belt Road (HI-11) is a 9.8 mile point-to-point trail located near Hawaii National Park, Hawaii that offers scenic views. The trail is only recommended for very experienced adventurers and primarily used for hiking.
The trailhead is on the highway & had lots of parking. The trail is paved and in nice shape. Went in a little way to explore and decide if we liked it. Definitely want to return. This appears to lead to several of other trails near by.
