The entire lower Puna area is open to residents only to facilitate evacuation should it become necessary. The main road into the area is suffering from massive cracking and SO₂ emissions. The other main road is only a hundred meters or so from one of the inactive lava flows. One of the minor connecting roads is now buried under lava, and the final one is an unpaved dirt road.

The nearby ocean is closed off to boats due to laze (that's steam mixed with hydrochloric acid and glass shards) hazard.

I was there just 5 days ago on an aircraft tour which flew directly above the fissures. We landed in Kona normally. The lava fountains are awe-inspiring. Here's what I was able to record: https://www.youtube.com/watch?v=9Pn1MiYB5KQ

Most of the island is fine at the moment, but lava flow access from the erupting area is likely neither legal nor safe at this time, though conditions could change in the future.

Is there line-of-sight from Mauna Loa? That would be a great bird's eye view, if possible. Of course, bring your telescope would apply.

Probably not. The height is above the cloud layer, and the flanks could well have too gradual a slope to see anything (as a result of being a shield volcano).

You can probably rent a boat to go see the ocean entry, I think hiking to the spot is probably not all that safe.

I'd rather watch from the safe distance of YouTube if you're going to walk there on land or something.

Helicopters are much easier to rent, if you only want to spend an hour looking.
