Bay of NaplesOne volcano, two buried cities
Mount Vesuvius and the two cities it buried in AD 79. All three sit on one rail line from Naples – and all three have had new rules since 2024.
Tickets and day plansPompeii tours, Vesuvius tickets, day trips
HawaiiWhere you can watch the Earth grow
Kīlauea has been erupting in episodes since December 2024, sunrise on Haleakalā is rationed, and Mauna Kea's summit road is four-wheel drive only.
JapanThe mountain everyone wants to see
Mount Fuji's climbing season is short and, since 2024, tightly regulated. You can see it all year – best in winter.
Guatemala and Costa RicaFire at night, acid lakes in the cloud forest
On Acatenango you camp across from a volcano that erupts every few minutes. In Costa Rica, park tickets are now online-only almost everywhere.
AcatenangoTwo days, cold, hard – and the Fuego ridge is off limits.PacayaHalf a day from Antigua. Guide required, no lava right now.ArenalPerfect cone, no glow since 2010.

No swimming.
IndonesiaSunrise over the Sea of Sand, blue fire in the crater
Java, Bali and Lombok have Asia's most visited volcanoes – and, since 2024, new fees, health certificates and quotas. In September 2026 two of them are only partly open.
Mount BromoSunrise over the caldera. The crater stairs sit inside the exclusion zone.Kawah IjenClosed since September 4 after a wildfire. Otherwise: health certificate and mask.Mount BaturBali's sunrise mountain. The hiking ban never happened.Mount RinjaniA serious multi-day trek with new rules since 2025. Currently partly open.
New ZealandRed craters, boiling lakes, an island no one lands on
The Tongariro Crossing barely works without a shuttle, not everything in Rotorua charges admission – and no one has landed on Whakaari since 2019.
United States – Yellowstone and the NorthwestA hole in the ground, a blown-out summit, a mountain of ice
Since January 1, 2026, visitors without US residency pay an extra $100 per person at Yellowstone, on top of admission. Further west in the Cascades stand the mountain that lost half its flank in 1980, the most heavily glaciated peak in the contiguous United States, and Oregon's home mountain, which charges no admission at all.
YellowstoneNo summit to climb – boardwalks past more than 500 geysers. $100 surcharge without US residency.Mount St. HelensJohnston Ridge has been unreachable by car since the 2023 landslide. See the crater from Coldwater or Windy Ridge.Mount RainierNo timed entry in 2026, $30 per vehicle. Sunrise Road closed after the wildfire.Mount HoodNo park entrance fee – but a $20 permit above 9,500 ft and Sno-Park permits all winter.
Why this site existsRules change. Travel blogs don't.
On Vesuvius the access rules were changed twice in 2026; on Teide, summit reservations now run through a new portal; on Etna, today's alert phase decides how far up you get. We back every rule with the authority's own source and its date – and we say what other sites get wrong.
Upfront about advertising
We link tours and tickets to GetYourGuide or Tiqets and earn a commission for it. Where the official ticket is cheaper, we say so.
Every place is different
On Vesuvius you lean over the rim, Pompeii lies under ash, and in Herculaneum you walk down into the city. The pages open the same way.
