Logan Cave - 4,290 ft. long, 152 ft. deep

Logan Cave is the very large and visible cave on the North side of the road in Logan Canyon. The gate was installed after the cave was vandalized several years ago. It is also in place to protect an endangered bat species know as the Townsend's Big Eared Bat. The cave is a total surveyed length of 4,290 ft. and 152 ft. deep. Carved by water seeping along the cracks and crevices in the limestone, Logan Cave formed to be very narrow, tall and wet.






This sign is posted just below the cave entrance to warn visitors to keep their distance to avoid disturbing the bats.

That cave is really cool inside. When I was younger with the scouts, we went into the cave in the winter because the water was low enough to wade through.
There is a crystal cavern that you have to climb a rope to get to, and it takes about 4 hours to get there.
Its ashame they have it closed. The bats are still there and people have been going in the cave for ever. I can't stand some laws. Especially the envri-nazi laws.

I explored Logan cave 3 times when I was at Utah State 1975-78. It was such a blast to do at night in the winter. While I'm sorry you can't go spelunking there anymore, I'm glad they are trying to protect the colonies of bats. It was an awesome experience!

This cave was awesome, and lended to the adventurous and squeemish alike. To the squeemish it was fairly open in the vertical sense and within it's depths one could lose their light beam searching for the ceiling. It meandered for quite a distance of level walking until the first challenge - that of a boulder to either crawl below (in ice-cold water - the depth varied by season) or to go over. Then there were the ropes - three different ones if I heard right. I was never brave enough to ascend the ropes, but still enjoyed the 3-4 times I went in. The first time I saw it riding back from Bear Lake with my sister. I made her stop and I followed a group of college kids in - I was equipped with just my sister's pen-light and after following the noisy bunch of youths for a ways the little light dimmed and I luckily made it back to the entrance before it went out. There were upper levels I noted that I saw boards crisscrossing a good way up and was also told of an entrance from atop the mountain into the cave. I'm glad I have those memories and was sad to approach the ominous bars that now cover the entrance. A harsh whip snap to the back of the neck with an oil dip-stick to the genius who tried to poison the bats, or the lunk-heads who started a campfire in the cave (I saw the ashes) and the scores of others who left trash. Off of the ole' soap box and let out a sigh.

We went spelunking a couple times in Logan cave back in 1973 or '74 while I was attending USU in Logan. It was an easy cave to get to, and to get through, once you convinced yourself to crawl through the shallow water on your belly under huge boulders. It was also a popular party destination for ROTC guys, and plenty of beer was consumed in that cave. I remember one brave soul who swam completely under water to get just one room farther into the cave. We were about 50% certain that we'd never see him again. (He made it back.)

Unfortunately not many people know the "real reason" that Logan Cave was fenced and locked off. The bat thing was only an excuse to do it! It was locked up shortly after a very close friend of mine fell to his death inside the cave. He only fell about ten feet or so, backwards, hitting his head on the way down. I hiked. walked, climbed the cave not too long before this event occurred, and guess what...there were NO BATS in the cave at the time!!! Imagine that.

I am trying to find a cave I explored back in 1994, Roughly 30-50 miles north of logan, It had a 30 foot rock face about 400 yard back from the entrance. Most ppl turned back from there but I met a group going further and we ended up going maby a mile or two. At the very back was a 3-ring binder and a wax pencil to sign that you made it. I was 13 and dont remember the name of the cave. If anyone might have an idea plz feel free to email me at sungod357@gmail.com. it was a amazing expirence and now 18 years later I am still Splunking and doing cave and cavern scuba. I was hoping to come back and do it again. I was pretty sure it was logan cave till i saw the pics...but of course things have changed. The place I went had parking within 1000 ft of the enterence. Left my camera in the back by the log book. So I want to re-shoot the cave.

When the cave was closed there were a total of 13 bats. Now the population of bats inside the cave is between 175 to 250 and has increased every year. Logan Cave is the largest and one of the only known caves in Utah that is both a bat hibernacula and a maternity colony. It is also one of only a few caves/mines that support Townsend'd big-eared bats. Townsend's big-eared bats are very sensitive to disturbance during hibernation and when they are reproducing.

Whats sad is that we let a few bats get in the way of people who want to explore caves. Why can't they do a permit system where a person takes a class about cave safty and preservation then is allowed in. My feelings is that the Forest Service and BLM would rather close a cave than to deal with potential problems in the future due to parties and accidents. As much mumbo jumbo about how this cave is the only cave in the area that these bats live in I'm not buying it. Just come out and say it's just too much paperwork to leave it open. Now for all you environmental hippies out there don't jump down my throat, I don't want to see these bats go exctinct or their number drop but lets educate people, keep it locked and allow serious people in with permits.

I was in Logan cave a couple times. Man, that water was cold!

People complaining about the closure and "enviro-nazis" need to grow up, take some responsibility and recognize that if we had taken better care of it, it would still be open.

As the guy said about the one guy that swam under into another 'room', I have heard that there a couple, and the last one is like an artisian well coming up from the floor. I'v also heard there are a couple caves in the rock bluffs across from the parking lot, across the lake just inside the overhangs. No doubt there are yet to be discovered caves in those mountains.

I was fortunate enough to explore Logan Cave in the early 90's with a group of Boy Scouts. What I remember is that the cave had 3 levels and we waded through ice cold water up above our knees for a long time. We used ropes to climb from one level to the next up very steep slippery rock faces. At the top of one rock face we had to crawl through a VERY narrow hole to the next level. For a while the walls were only a few feet apart and stretched straight up out of reach of our lights. We went ALL the way to the end of the cave on the 3rd level to a small room and signed a book that was there. I crawled all the way back and put my face to the floor and could see a hint of light coming from the other side of the mountain but a person can not fit through there. It was one of the greatest experiences of my life. Except for the part where my flashlight died on the way out and my foot fell through a hole in the floor. I fell right on my ass and pulled my groin! Hurt for days :P I make this trek again in a heartbeat if I could!

I explored Logan Cave with some friends in 1984 when I was attending USU. We only went a few hundred feet inside. I wanted to go on but everyone else got tired of wading through the icy-cold water and vetoed that suggestion. I tried to find others interested in exploring further, but no luck. I had heard about the crystal room and wanted to see it.

While attending USU ('67-'72), exploring Logan Cave was one of many adventures I enjoyed taking with a group of my DSP fraternity brothers and friends. Our three and four hour treks into the cave (never saw any bats) are one of many lasting memories of my time spent in Cache Valley, along with Beaver Mt. skiing, tubing down Logan Canyon, and exploring all the mountain trails. They really ought to consider opening up the Cave, at least, to guided tours. This cave is, indeed, a rare find.

I wish it was still open. I love to go caving and am a new resident in Logan. Such a sad thing. Why don't they issue permits for caving? It could create revenue for the government, and it could create accountability for the individuals on the permit.

Stupid bats, wanted to take my kids there after I signed the book, but nooƓoo, screw dumb bats lol, people should clean up after themselves
