Up until the recent Kilauea eruption in 2021 there was a period of about 30 years where you could hike up to molten lava flowing from the pu'u o'o vent on the southeast slope of Kilauea. The length of the hike varied from a few hundred yards to several miles depending on which way the lava was flowing. The 2021 eruption drained the lava from pu'u o'o and it stopped flowing, and the only exposed red lava was in the Kilauea summit caldera, and the only (legal) way to see it was by helicopter. So the TL;DR is: it depends. At the moment it's not looking good for easy access, but stick around, the situation is bound to change. A week from now you might be able to see lava flowing in the streets of Kailua or Hilo.
