Hola Buen Dia, se puede llegar comodamente hasta el parque en cualquier medio de transporte, tiene estacionamiento propio con costo adicional o lo dejas fuera del ingreso y caminas unos metros.-

No. You can view from car park end. Steps are steep.

We were there and it was raining.. not many steps. They are at the beginning of the walk. We took the short route and did not walk around the entire path. So you walk down the stairs to a solid path. Can’t remember if it was asphalt or cement but the path is wider then the stairs and hard surface. They stairs are easy to go down even when wet. The path does go up and down but if you take your time your good. There are plenty of areas to stop and admire the tropical landscape. Definitely a must to see. Restrooms in the parking lot. Coming back on the path is easy. When you come to the steps they are easy to climb as far as condition and rise of the steps. Take them in sections and rest if you have trouble with steps.

The Tsunami museum ..walk the Memorial park..Coconut Island..Ken's pancake house..Rainbow Falls..Mauna Loa nut factory.. Big Island Candy..Mehana Brewery ..the Hilo Market..watch the Canoe club members.. eat at Cafe Pesto.That might do it

I walked the paved pathway wearing flip flops with no difficulty at all. So the shoes you describe should be fine.

Absolutely doable!! :) they are not far from each other!

The easiest way to get around is to rent a car. The airport in Hilo has all the major car rental agencies. Akaka falls isn't too far from Hilo, maybe 10 miles or so. It really shouldn't take you more than 45 minutes to an hour to take the very short loop trail to see the falls. This isn't an all-day event. Unfortunately, Hawaii Volcanoes Nat'l Park is closed. However, if you go to the town of Pahoa, there is a church on the southern end of town that has a pretty impressive view of the glow from the lava. There is heavy Nat'l Guard and police presence. Unless things have changes in the past few weeks, you're not going to get close to the actual lava flow. But in Pahoa, you can see the glow and steam coming off the lava. Of course, go after dark!

No. In fact it is very dangerous and yearly they have people who die there.

Lots of Uber and taxi also maybe a tour group is likely to a couple of spots.

We rented a car. Not sure the cost of a taxi.
