Wow you just took me down memory lane. My wife and I lived on the Big Island for a little over 4 years. I have done that hike so many times! Such a great experience every time. You should go to the Hilo Farmer's Market tomorrow (Wednesday). It is awesome. We ran a fresh salsa business there for a long time. I miss Hawaii. I hope you have a great time! Aloha.
Peace,
