Sonja and Alex's spot is a magical place on edge of the Big Island. Built on hardened lava, the terrain is extremely unique. We were lucky enough to reserve during a new moon; which allowed us to see an incredible amount of stars in the sky since there is zero light pollution. You can literally see 20x times as many stars across the dome of the sky!
The place itself was very clean in and homely. Outdoor shower worked surprisingly great!
Keep in mind that it is a journey to get to this spot...lots of unpaved road travel (and anxiety that you might pop a tire!). Your best food options are 20+ minutes away so keep all that in mind. But it's 100% worth it.
