Often, during the hottest days of summer, the only cool spots are indoors with the air conditioning turned up high. But who wants to stay indoors when you are on vacation? It is true that your Sunriver Pines vacation cabin is cozy and comfortable and filled with fun things to do, but what kind of vacation would it be if you stayed inside the entire time and never explored the sights? Fortunately, Sunriver rarely gets too hot to enjoy all the Sunriver things to do that surround us, but on the days it is just a little too sticky to be outside for long, why not head underground? Lava River Cave in Sunriver is a mile-long lava tube located in the Newberry Volcanic Monument, and the average daily temperatures only reach up to the mid-40s; even in the summer!

Created by Molten Flowing Lava

Lava tubes are naturally created as molten lava cools, and the Lava River Cave in Sunriver is the largest lava tube in the state of Oregon, about a mile and half in distance. A series of stairs throughout the cave allow you to reach the bottom easily, but if you aren’t in the best physical shape, just take it slow. Once you reach the bottom and begin your tour of the lava tube, you may discover that your summer gear is not enough to keep you warm; temperatures in the 40s make it advisable to wear long pants, closed toes shoes, and a jacket or coat! Refreshing in the hottest months of summer, it will take you about an hour and a half to make your way to the other end of the lava tube, and by that time, you will probably be welcoming the sun and warmer temperatures! The Lava River Cave in Sunriver is only open from May through October; this helps protect the bats that make the cave their home. After October, it’s just too cold, anyway!

An Otherworldly Beauty

As you head below the Earth’s surface, you may start to feel as if you have left Earth altogether. The rocky walls of Lava River Cave in Sunriver still bear the designs the molten lava left behind as it flowed. The floors underneath your feet appear to have been made of waves, and the icicle-looking stone formations hanging from the ceiling aren’t stalactites; they are actually areas where the rock liquefied during the volcano explosion and then hardened again. Exploring the Lava River Cave in Sunriver is an adventure like any other and should not be missed!
