Pololu is at the end of the main highway through North Kohala. It was popular with bike tour operators who would drop their clients in Hawi for the 15 mile round trip to Pololu lookout and back. However, the stretch from Kapaau is narrow and winding and the shoulder is slim to non-existent. It also gets a lot of traffic with people keen to see the views without getting all hot and sweaty. So after some accidents and more near misses, people lobbied to have the bike tours banned. This duly happened and is, on balance, a good thing I think.
I did like this sign, about 100 yards from the road end at Pololu. It seems a bit late to warn about the ban, but perhaps it’s meant to discourage tour operators from driving their clients to the end of the road and having them cycle back!

That certainly is a sign I have never seen before, Graham.

I wonder if it reduced the bike tour companies insurance claims as well

We went to the overlook in September, and it was much better than I remember from previous trips. Not the views, those have always been awesome, but it was better managed. Didn’t notice the sign though. 😀

Yes they’re definitely better organized and the parking isn’t quite so chaotic.
