For those interested in some Upcountry sights, check out the Hui No'eau Art Center, located on Baldwin Avenue in between Paia and Makawao. It once was a family estate (the Baldwin family), called Kaluanui, and has been lovingly restored. It has a wonderful view out over the slopes down to Kahului and across to the West Maui Mountains. The hybrid Norfolk-Cook pines that flank the driveway are incredible, and are thought to be two of the oldest trees on the whole island. The Center also has rotating exhibits, and a very nice gift shop with some wonderful wood pieces. Here's a link to the Hui's site:
In the same area stands Makawao Union Church. Connected to the Baldwins as well, the stone church is really beautiful. If you're ever on island and have the chance to attend a concert there, the acoustics are incredible. Here is a link to a wiki page about the church:
The Baldwin family has always been, and still is, a major force in Maui. They are also known for their philanthropy, much of which is quietly accomplished behind the scenes. Colin Cameron, a Baldwin descendant, was the developer of Kapalua, but few people know the extent of his gifts and sacrifices for the people and to preserve the history of Maui. Here's a link to a page about part of the family: en.wikipedia.org/wiki/Henry_Alexander_Baldwin
Pi'iholo Ranch, still owned by Baldwin family members, continues to preserve history and protect resources here. When they began offering tourist activities, many felt they had "sold out". But as Peter Baldwin said, the ranch had to change and grow in order to survive. They run ziplines and horseback rides---but still ranch and are very involved in preserving Maui's ranching legacy for generations to come. Along with Sumner Erdman of Ulupalakua Ranch, this family is responsible-- IMO-- for the vast open pastures and ranchlands one still sees. They are truly stewards of Maui Nei.
Other sights in the Kula and Ulupalakua area include the winery and Holy Ghost Church.The history of the winery is well documented-because it was part of the Rose Ranch, which later became Ulupalakua Ranch (as it's known today). Holy Ghost Church was built in 1894, and carefully restored and preserved over the years. The first masses were celebrated in early 1895. It is built on land donated by the Von Tempsky family, another old Maui family which was heavily involved in ranching and the community. Here's a link to the Wiki page about the Kula area; scroll down and you'll find some other links and info, plus a link for the church: http://en.wikipedia.org/wiki/Kula,_Hawaii
Also, don't forget to take a few minutes to enjoy the beauty of St. John's Episcopal Church, in Keokea, the Sun Yat Sen park, the views from Rice Park, and so much more. The whole Upcountry area is a feast for the senses!
