We thoroughly enjoyed our stay at Oma's place. It was easy to find using Google maps and in a great location.
Upon arriving Todd walked over to greet us and gave us several good recommendations on what to do in the area. The location can't be beat if you want to spend a couple days in Volcano National Park. Only 1 mile away from the entrance it took us 3 minutes to drive there. The cottage itself is cozy and well maintained. The kitchen is well stocked with anything you need to make basic meals. We were four adults and found it very comfortable and secluded.
On our first full day we woke up early and went to the Sunday farmer's market, which Todd recommended. It's small but with a great selection of local tropical fruits and vegetables as well as some hot food. We loaded up on strawberry papayas, passion fruit, and rambutan. Then we headed into the park for some guided tours. At lunch time we just drove the 3 min back to the cottage, made lunch, took naps and then returned to the park at 2:30 for the Above and Below tour at Kiluea Iki lookout. All super convenient. After hiking the Kiluea Iki trail we returned to the cottage for showers and a change of clothes and walked to dinner at Ohelo Cafe, which was delicious. After dinner it was dark enough to return to the Jagger lookout point and watch a molten pool of lava bubble and burst on the horizon. And that was just our first day, no wonder we were exhausted. Jagger lookout is also one of the best places to watch the sunrise on the Big Island if you're jet lagged and waking up at 5 AM like I was.
