We'll be there for our 25th anniversary (to give you an idea of our age) in late May. I've done research, but I am having a hard time narrowing down what we can get in in 5 days! We've been to the islands twice before, but this is our first time on the Big Island. To give you an idea of what we like to do, we live in the northern Rockies and like to ski, hike, river kayak, and ride (horses). We also like to sail, snorkel and have been certified divers for decades, but rarely get to do those. We don't golf and we're not into shopping. We enjoy music, history, new cultures and nature. We don't want to engage in activities that the locals find offensive. We're looking for some new experiences that we can't get where we live, but we would enjoy a similar type of activity in a new setting. We're not well-off, so we have to carefully budget the pricier adventures (thank God -- and the U.S. taxpayers -- for our national forests and parks!). We will have a rental car. Thanks, Tripadvisor readers!
