Good for what we saw, just not as interesting as other sites on the Big Island.
The tour was very informative and the sites were interesting. We finished in 3 and 1/2 hours and it was booked as a 4 hour tour so I think we could have spent a little more time at some locations especially the National Park as there was an interesting self guided tour but we had to rush through it. Our guide was very knowledgeable.
The Historical Refuge Park is a must see and very relaxing. Most interesting was St Benedicts's Painted Church. Imagine a priest sent to this side of the island not knowing how to communicate with people then painted murals so they could understand him.
