We just got back from driving the Road to Hana....all day. We were using a "Lonely Planet" book from 2004, and after so many years, it was still very accurate!! There was only one section of the book where we became confused....the section about the "Blue Pool." As we headed down the dirt road that our guidebook directed us towards we noticed the "No Trespassing" signs.......there was no mention of this in our travel guide. Being the curious main-landers that we are, we decided to head down the path until we came upon the Botanical Gardens. At that point we asked the attendant, at the entrance to the gardens, about the Blue Pool. She kindly mentioned that due to the number of visitors, and it's proximity to people's private homes, the owners of the homes have asked visitors to not trespass. She thanked us for asking rather than simply entering people's properties without their permission. This being said there are SO MANY OTHER waterfalls, pools, plant life, and sights to see along the Road to Hana. It's worth it to show the locals some Aloha spirit, as so many of them have shown us the entire time we've been in Hawaii. Every day so many visitors pass along the Road to Hana in order to experience and see a part of Hawaii and a lifestyle that has been preserved, embodied by the fact that a 2004 guidebook was so accurate all except for the Blue Pool section. For those with a sense of entitlement, there's no wonder so many locals detest the tourism that has taken over many parts of the Hawaii they once knew. With so many other sites to see along the Road to Hana, and throughout Maui, why not just appreciate what our tax dollars, and so many of the locals, have done to preserve Hawaii.
