Plan a trip to blow off some steam.
Over hundreds of thousands of years, volcanic activity has yielded a breathtaking array of breathtaking features, from craters and calderas to lava flows and lava tubes.
And these features aren't just terms from your elementary school science textbook: You can actually see them up close. All you have to do is hike an active volcano.
To help you get started planning your next adventure, we've rounded up 15 hikeable volcanoes around the world that draw thrill-seekers, nature enthusiasts, and mountain climbing experts to their awe-inspiring peaks. A few are easily accessible to beginner hikers, while some require gear, technical climbing skills, high levels of fitness, and a fair bit of courage to reach the summit. And plenty of others offer a variety of spectacular trails in between the extremes.
But no matter which volcano you plan to hike – whether it's consistently quiet or continuously erupting – make sure you're up to speed on its alert levels before you leave for your trip, as trails may be temporarily closed due to strong gases, eruptions, and other volcanic activity.
