I've spent a few days in Volcano national park, right before the 2018 eruption. We could see lava splashing in the caldera from an observation point (Which has been closed since then - not that it would be of much help, since the lava level has also dropped.) We could hike geologically active areas (sulfur vents), and across decades-old lava flows. The latter was an incredibly surreal experience, due to the sharp transition between dense jungle and alien wastelands. There were hiking tours available for walking up to the lava at night, but they seemed pretty sketchy.
