Before heading out, be sure you've prepared accordingly - dress appropriately with the right footwear for your adventure be sure to keep water with you at all times, it can be easy to get dehydrated on the lava fields. If the flows have recently been near the surface within the Park and IF it's safe to access (check with the Rangers), it's pretty easy to locate the lava yourself - so don't feel like you HAVE to join a tour to experience a lava flow. Just remember, this is an active living and breathing volcano and things regularly change, the maps are always out of date for that reason to some extent. We've also included some maps below to generally help provide you an overview of the park and where the lava might be located during your visit.

By the end of the 2018 eruption, the Halemaumau crater had sunk by 1,600 feet (488m), and its diameter more than doubled. Every 28 hours, on average, the ground within the summit caldera of Kilauea sank with dramatic collapse events. With less magma left to support the summit, the Halemaumau crater began to collapse. On May 3rd, the first fissures opened up in the subdivision of Leilani Estates and the massive eruption of 2018 began to unfold in lower Puna. Magma moved from the summit of Kilauea to the Lower East Rift Zone, marked by a series of earthquakes. In the first days of May 2018, the lava lake that had existed in Halemaumau crater for almost a decade began to drain away. See the maps immediately below to get an idea of how volatile the years between 20 were at the park or explore this geo-narrative by the USGS about the 2018 eruption. Kilauea caldera has undergone a tremendous amount of change over the last decade, and prior to the eruption in December 2020, had not been very active since 2018. The eruption paused in late May 2021, after several months of activity in the Halemaumau crater. By the morning of 12/21/20, two of the three initial fissure vents on the wall of the Halemaumau crater were feeding a growing lava lake.
