just got back it was a pretty awesome time I caught some lizardfish, trumpetfish, and needlefish all on the fly rod. There are plenty of fish but my main problem was getting the fly down so it should be bad if you are bait fishing just bring some heavy sinkers if you get to go at all with their recent travel ban.
There are some giant bonefish that come out of Maui, but they’re pretty far and few between. Like you I’ve pitched flies along the shore and caught small reef fish, but I think hiring a guide would be the way to go to find bonefish.
I charter fished out of Lahaina (or very near as that's where we stayed). Its literally, get out of the harbor and drop lines. No long boat ride etc. You might want to think about that if you have time. A "make up" charter with others can be pretty cheap.
Wow, I just got back from Maui on Sunday. The natives were becoming pretty hostile by that time in regards to non- residents. When we were there, we took the ferry to Lanai and spent the day Jeeping around. That whole island seems like it's managed for hunting. Plenty of wildlife. Think I'll bring the bow if I go again next year.
Whereabouts were you fishing? I was staying in Kaanapali, just a mile north of the Black Rock.
