This is a great rental, not where most tourists are. It's absolutely beautiful and there's much to do. We are a family of six with adult children (20-24 years old). We walked the area a lot to swim and get a feel for where we were (plants and other life, houses, land). We kayaked to Captain Cook and snorkeled/swam, swam/snorkeled every day close to the rental, jumped off rocks into the bay one day (be careful), toured a coffee farm, went to Volcano National Park, went to a bee farm, hiked the rainforest, walked to a close, roadside fruit stand/bought Kona Chips (potato)/had fresh fish/had dinner out once.
We all really enjoyed it.
I recommend water shoes for walking on the rocks and swimming. The flat rocks can be slick. Volcano rock is hard to walk on. If you have goggles or a mask, bring it. They have a couple at the house to use. DON'T get the Nissan Armada as a rental car. Get something smaller to get around easier. There's a one-lane road to get to the rental, and there are many winding, high-up roads you drive on without much shoulder. Beautiful views but, at times, scary. Don't let this discourage you from the rental. It's awesome.
A sincere THANK YOU, Regina and Kalani, for renting us your home!
