Valentine Cave
Valentine Cave is one of the most accessible lava tubes at Lava Beds National Monument. A short walk from the parking area, a paved path to the entrance, and the first 200 feet are smooth, flat, and well-lit. Most visitors stop here. The cave continues for another 1,600 feet of rough, rocky terrain that requires a headlamp, sturdy boots, and some comfort with tight spaces.
The easy part
The entrance to Valentine Cave is through a collapsed section of the lava tube, where the roof has fallen in and created a natural amphitheater. A paved path leads down to the cave entrance, and the first section is wide, tall, and easy to walk. The floor is smooth basalt, the walls are lined with lavacicles (lava stalactites), and the air is a constant 55°F.
This is the part most visitors see. Families with kids, people in sneakers, folks with phone flashlights — they all make it this far, take a few photos, and turn back. And that’s fine. The easy section of Valentine Cave is worth the trip on its own. The lavacicles are delicate and beautiful, the smooth floor reflects your light, and the scale of the cave is impressive.
The hard part
After the first 200 feet, the cave changes. The floor gets rough — a’a lava, broken rock, and debris from ceiling collapses. The ceiling gets lower in places, requiring you to duck or crawl. Side passages branch off, some dead-ending, others connecting to the main tube. The darkness gets absolute, no light except what you bring.
We went about 800 feet past the easy section before turning back. The cave continues, but we were alone, our headlamps were dimming, and the rough terrain was getting harder. We saw no one else in the back section of the cave, everyone else had stopped at the entrance.
What we learned
Valentine Cave is a good introduction to lava tubes. The easy section shows you what a lava tube looks like, smooth floor, lavacicles, constant temperature, without requiring any special gear or experience. The hard section shows you what lava tube exploration can be, rough, dark, and solitary, if you’re willing to go past where everyone else stops.
One story is that the cave is named for the Valentine family, early settlers in the area. The name has nothing to do with the holiday, but it fits. Sources say that the cave gets its name because it’s dicovery occured on Valentine’s day in the 1930s. Valentine Cave is a good date, easy enough for anyone, with a back section that’s more adventurous if you’re up for it.
