This might be one of the coolest adventure travel experience's we've ever had - going Into The Glacier in West Iceland.
Into The Glacier offers several different tours with the main attraction being the ability to go inside a man-made ice cave inside Langjökull glacier - Iceland's second largest glacier (also the main water source for everyone living in Reykjavik). The classic tour takes between 2-4 hours departing from Hotel Husafell.
To get to the glacier you hop in this massive ex-military vehicle that's pretty much been converted into a snowmobile bus. Once you get on to the glacier, you'll see snow in every direction as far as the eye can see.
An experienced guide will take you into the cave and guide you through it's tunnels once you're inside. LED lights are used to light up the interior ice walls.
Your guide will teach you a ton of interesting things about glacier life like how quickly it's melting, what Iceland's Eyjafjallajökull volcano eruption in 2010 did to the ice, and how long it took to build the tunnel.
The tunnel has a handful of rooms including a small room of worship with incredible acoustics. Lucky us, our guide happened to also be a professional singer.
Most importantly, don't forget to taste that crisp glacier water. You might have to stand in one spot for a while, but it's worth it.
Into The Glacier. Tours start at $188 per person.
