My wife and I went on a Saturday night where they had a cultural presentation from a couple locals. It was interesting but the best part for us was the star gazing. They setup telescopes and point them at various objects in the night sky such as the Andromeda galaxy, Betelgeuse, and Jupiter. These were amazing to see through the telescopes. A few tips if you want to have a nice time is wear warm clothing including hats, gloves, wind breaker jacket, warm underlay such as a fleece. It can get into the 40's at night here and any wind will make it that much colder. We were lucky enough that the temperature was in the 40's but no wind, still being outside for 2 hours in that can be very chilling. The visitor center has hot water and you can purchase tea bags or hot chocolate packets. Also, bring a flashlight, preferably one with a red filter so you don't ruin your night vision. My wife and I walked across the street along a trail leading up to one of the cinder cones, halfway up the trail we stopped and walked off the trail about 100 feet and just sat down. I would highly recommend doing this for the best view as it is away from all of the people and lights of the visitor center, you will see so much more of the night sky. I took some amazing long exposure pictures as well.
