Arenal Volcano in central Costa Rica is famous for its picture-perfect views and until 2010 was considered to be the country's most active volcano. Nowadays, you can visit Arenal Volcano National Park for hiking, Lake Arenal for fishing, boating, and windsurfing, and relax in the natural hot springs located nearby.
Luckily for visitors, things have calmed down a lot since the massive eruption in 1968 that destroyed three villages and killed 87 people. Today, Arenal remains a popular spot along Costa Rica's tourist trail and plays host to outdoor activities like hiking, canyoneering, and whitewater rafting as well as horseback riding.
One of Hawaii's most iconic postcard images is Diamond Head, a dormant volcano offering gorgeous views overlooking Waikiki and the southeastern part of Oahu. Allow up to two hours for the round-trip hike, bring plenty of water, and don't forget to wear sunscreen as the afternoon Hawaiian sun can be quite strong.
Diamond Head State Monument is open everyday from 6 a.m. to 6 p.m., with the last entrance to the hiking trail at 4:30 p.m., and costs $5 per car or $1 per pedestrian. The semi-strenuous hike takes you up 560 feet from the crater floor in the first 0.8 miles on a paved walkway, through 0.2 miles of switchbacks, a 225-foot tunnel, and up 99 steps to the summit.

One of the most notorious volcanoes in Italy, if not the world, Mt. Vesuvius is best known for its dramatic eruption in A.D. 79 that obliterated ancient cities and froze the nearby town of Pompeii in time, burying it under mountains of hot ash and preserving its citizens and their homes for centuries. Here, a view of Mt. Vesuvius as seen from the ruins of Pompeii.
Several tours are available from Naples, Italy, to visit Mt. Vesuvius, where you hike to the volcano's summit and look down into the still-smoking crater.

Buried deep beneath Yellowstone National Park lies one of the world's largest supervolcanoes—its next eruption is predicted to be catastropic for the U.S. although its not known when it will occur. Until then, you can visit natural attractions within the park, like Grand Prismatic Spring, the largest hot spring in the U.S., and just enjoy the view.
Visit Yellowstone if you're looking for a great family camping or road trip, and are up for hiking, fishing, biking, or horseback riding during the summer, or cold-weather activities like snowshoeing and cross-country skiing during the winter.

Not into heavy duty hiking and climbing? Check out one of the area's hot springs or spas at Villarrica or nearby Curarrehue, Malalcahuello, or Curacautín.

About an hour's drive outside Hawaii Volcanoes National Park along Highway 130 in Puna is the entrance to Kalapana, a Big Island town that was completely covered by a 1990 lava flow. The hike ends at a gorgeous black sand beach (swimming is not permitted due to the proximity to the active volcano, Mt. Kilauea). The best part: both parking and hiking are free.

Santorini may look quiet and peaceful today with all its colorful buildings, but thousands of years ago, a catastrophic eruption took place, effectively burying an entire Minoan civilization under volcanic ash for nearly 4,000 years—unlike their ill-fated counterparts in Pompeii, however, the people here escaped, leaving behind a ton of artifacts at sites like Akrotiri.
The eruption of Thera, the Greek volcano that helped shape Santorini and several other Greek islands, is said to have been five times as powerful as the 1883 eruption of Krakatoa, Indonesia. Many believe the original Minoan ruins were once the mythical city of Atlantis, a legendary city believed to have been destroyed by intense natural causes.
