Phenomenal experience! Found a partial stingray fossil, which had always been on my bucket list. They were extremely helpful and knowledgeable. Great quarry for experienced diggers or first-time beginners. They provide all of the tools (hammer, chisel, and saws to trim the fossils before you take them home). Paid for a full day of digging and found over 50 complete or nearly complete fish! About the only things you need to bring are water, snacks, gloves, sunscreen, and something to transport your fossils in (I used a milk crate and bubble wrap).It’s awesome they let you keep practically anything and everything you find (with an individual specimen value up to $100,000). If you find any of the rare stuff (gar, stingray, paddlefish, turtle, bird, bat, etc), you can keep it. Will definitely be coming back!

Flew into Salt Lake City and went directly to the fossil Lake safari quarry. We had such a wonderful experience, even better than what we imagined. The staff were very helpful and knowledgeable!

I had a great time at Fossil Lake Safari! Everyone there was so nice, but Kaden was incredible. He was so helpful in showing us what to do and would check on my husband and me throughout the time we were looking for fossils. He offered very helpful hints and tricks and had a lot of information on what we were finding. It was a great experience and we are so happy with all of the super cool fossils we found!

We had an amazing time hunting fossils here. The family/owners are wonderful and their workers were friendly and helpful. It was so much fun uncovering the fossils, we will definitely go back and make this a definite destination! We went July, 2024. I bought entrance online prior to the day we went, it was very easy to do. Highly recommended it!!!

Best experience ever, so worth the side trip. Just bring your work cloths, a shade hat and water.Staff was wonderful, they provide the tools and gloves. Had I known that we’d find over 30 fish fossils in 2 hours I would have brought a box and some packaging paper too. They let you use their tile saws to trim up your pieces. If we didn’t have a tight schedule we would have stayed the day. Our two hours did not count the upfront instructions or the sawing afterwards. We had a senior and a 11yr old with and they loved it too.

We spent a Saturday looking for fossils and had SO much fun!! The guides were friendly and informative. They really know their stuff! We found a lot of fossils and had a great time. They even cut your fossils out of the large rocks so they can be easily displayed. Such a great time for our family. Beautiful area, too! We plan on going back!!

Amazing fossil site, staffed by some very knowledgeable individuals. Although most of my specimens that I found were small fish I noticed that other people around me were really scoring big on some nice specimens. I would certainly recommend this fossil site for anyone looking to gain some experience. Highlight of my experience was learning how to clean and identify fossils that were not exposed.

We had a lot of fun! Shonda, helped check us in and explained the rules. She is very friendly. Kadan and Afton, employees, walked around and answered all our questions, they got excited with us as we found fossils. They even helped us when needed. Kianu, cleaned up our fossils and made them look beautiful. Each of the employees were kind to everyone digging. They let us go at our own pace. We had a member of our family get a finger smashed pretty good. All of the employees kept calmed and attended first aid quickly and kept us grounded and even helped us laugh to stay calm. They took good care of us and made sure we got all our fossils when some of us had to leave early.

We had a blast finding fossils at Fossil Lake Safari! Everyone was super helpful and friendly too. We did 4 hours and it was about perfect for us. They have everything you need there to find the fossils. I am happy we brought gloves but I wish we would have also brought knee pads or a pad to sit on.

This was an amazing experience and I could see it being super fun for people with kids. I went by myself on a whim and spent the entire day open to close there. If you've ever wanted to pan for gold but with fossils this is an experience. The staff was incredibly friendly and showed me the ropes and were as happy as I was to see anything I found. Keanu helped me throughout my day and was insanely knowledgeable in everything I had a question on (and I had a lot of them). Unfortunately I can only give 5 stars, if I could I'd give 10.

Great fun, great staff, and hard work! I decided to try a fossil hunt here, this Tuesday, and was happy that I did. The staff -- especially Tim and Afton, with whom I most interacted -- was super-friendly and helpful. I found some very nice specimens, which they trimmed with big saws before I left. It was a day well spent - and it taught me never to be on a chain gang, especially one tasked with breaking rocks all day. Ha!

I recently did a four hour dig at Fossil Lake Safari and had a great time. It exceeded my expectations. I brought home 25-30 fossils. The people running it were so nice and helpful and made sure everyone got started out right and found fossils. I could have spent all day there for sure. I’ll be back.

Taking a break from this internet age thriving for instant rewards, we spent a day with Fossil Lake Safari, taking away a tactile, fun and engaging Cenozoic adventure.Following the directions on the website, we took a scenic drive to the quarry. Upon arrival, friendly staff greeted us, gave us tools, explained and showed us what to do. Matt, the owner of the operation, demonstrated how to split rocks and patiently explained everything ranging from the how-to's, geological formation to fossils. Others at the quarry were also friendly and very knowledgeable as well. We found quite a few fossils, with my daughter having the best of luck of finding a rare partial heliobatis (stingray), all of which we got to take home.We brought our own lunch (sandwiches from the Opera House Store were great), and the Safari had snacks and spring water, which actually did taste better than tap water!It was a fun, enriching and rewarding experience, one entirely different from our daily experiences. I asked my daughter if she'd go back again, and the answer was yes. Well, I think we will be back!

I tried two different quarries on this trip. I had fun at both, but I found WAY more fish at this quarry. The staff was very friendly, helpful, and knowledgeable. I can't recommend these guys enough. If you want to dig fish and guarantee finding some SWEET fossils, then I'd highly recommend visiting this quarry.
23:53 17 Jun 24
It was a great experience from checking in to getting a spot to split rock. Everyone is super friendly and loves being out there. The guides were fun, very helpful and informative. I had plenty of rock to split and found lots of great fish! Plus there was snacks, coffee, cocoa and spring water available. I’ll definitely be returning!

Stop what you’re doing and make a reservation to go to Fossil Safari right now!!!I’m an amateur paleontologist and I had always wanted to dig fish fossils. A friend of mine discovered Fossil Safari and he made reservations for us.The directions to the quarry are perfect. Driving out to the quarry is part of the adventure! During the 20 minute drive you will be sharing the road with hundreds of cows and sheep.We arrived at the quarry at 8 AM right when they opened. We were immediately greeted by several staff members who welcomed us and taught us the procedure for splitting open the rock containing the fossilized fish.During the day, staff members would stop by frequently to ask if we needed any help or have any questions. I simply can’t say enough about the staff. Everyone was knowledgeable, friendly, engaging and just super nice to spend a day with. It was reminiscent of summer camp. I’m calling it fossil camp!The facility is top-notch. They have a store where you can buy sodas and get water. They also sell fossil books and T-shirts.By the end of the day we had over 100 magnificent fossil fish to take home with us. We could not have had a better experience. I really can’t think of any suggestion that would make Fossil Safari better!Thank you Fossil Safari! We will be back!John, Jim and Kendon

This was such a fun activity! I went with some of my family and we did the half day dig. It was well worth our time… we found some amazing fossils! The staff were super helpful, knowledgeable and friendly. Definitely wear gloves, long pants and a hat. Bring plenty of water. This is an activity I would do again!

I had a recent private dig with these awesome folks. We found more fossils than we could carry lol. We found lots of fish and a croc tooth and croc "poop". Every member of the staff was professional, friendly and just fun to be around. Most of our day was spent with Keanu and he was so good with everyone in the family. I ended up having an unrelated health emergency and these folks were on it. They stayed by my side and kept me going until an ambulance picked me up. Many thanks to Doug and his wife for their care while waiting, I know it made a huge difference. These people are truly amazing and when I get my issues resolved I will be back!!!! Seriously, this place is THE place I will recommend!

We had a fantastic time at this extremely well-run and organized quarry! We are total beginners, a family of 4 with two 7 years old girls, who had a blast looking for fossils. The entire staff is incredibly friendly, knowledgeable, and helpful. We spent a full morning there of about 4 to 5 hours and our girls did not want to leave! They supply gloves, glasses, chisels, and hammers and expert instruction. Bring lots of water and sunscreen and prepare to get dusty! We especially appreciated the knowledge and help of Afton, one of the experts at the quarry, who patiently guided my girls and helped them open a huge rock to find 3 beautiful fish. It was the highlight of their trip! If you love fossils and are looking for a fun family activity this is the place! We are loaded down with beautiful fossils to take back to Houston, Texas!

We traveled to this place in early June and it was astonishing! The people were so kind and patient with us showing us how to split the rocks and what to look for! We learned quite a bit from them in just the short time we were there! Would love to revisit and hear some more jokes from the tiny foreman someday!!

Definitely worth the admission. We found a lot of high quality fish and even a partial croc tooth. The people running the quarry were extremely helpful and kind. We have done three trips to Kemmerer for fish fossils, including both public quarries, and this was easily the best experience we have had!

Had an amazing experience! Doug and Keanu were super attentive and knowledgeable. Half day was plenty to find some nice fossil fish. Brought gloves based on past reviews but didn’t use them… Would have rather brought knee pads or small stool, either way super doable without. Could see a bandana or face mask being 100% needed if windy.

Spent the last two days visiting this quarry. The first day we spent the full 8 hours. We learned a ton about the fish, turtles and other species found in the quarry. We enjoyed ourselves so much we came back for a second day. All the staff at the quarry were super knowledgeable and helpful! We came home with a ton of awesome fossils. We can’t wait for our next trip.

If you are in the area check them out but do NOT follow Google gps to get there. Use the directions from the website. Made the drive and my 3 and 1/2 year old and husband had fun smashing the rock to find fossils. Definitely want to layer up as it was quite windy when we went.

A life long dream come true at the age of 59. I am still so delighted over getting to do this.While this review might have some whining in it. I absolutely do not regret coming here and highly recommend it. But there is a learning curve. So please learn from our mistakes.1 negative that is not this places' fault.DO NOT FOLLOW YOUR GPS without really checking into it first. We were coming from Afton WY and our GPS had us turn on to the most awful washed out dirt road I have ever been on in my life. I think it was about 7 miles later we encounter a closed gate with a sign telling us no access to the quarry and it had directions on how to get to the quarry from Kemmerer. Yikes! LOL so we risked our vehicle back down that horrible road to get back on the hwy. Thank goodness we did not damage our vehicle. Sadly that debacle with that GPS misdirection lost us a hour that was planned for digging. :'(You really want to head there from Kemmerer.The quarry is a long ways down a well maintained dirt road. We checked in, were provided with gloves, a chisel and a hammer. We were given a quick instruction on how to split the rock and find fossils. We were directed to lines of rocks laid out and asked to stay away from the quarry walls and set free to find what we could find. At this point it really is just down to luck.We made it there with only 3 hours before they closed. But with the heat and sun I don't think we could of done 4 hours. It was in the afternoon.I was so worn out. I still had not gotten my perfect fossil. I told myself that the rock I grabbed was going to have to be the last one for the day. Bingo, perfect negative and positive fish!!Then we brought our discoveries to be cut down and reloaded our stuff.I do regret that was that I was so wore out. As there were plenty of fossils we found that we were just too dang tired to haul over and load up. I now really wish we would have suffered thru loading them up. Because I wish I had them. Especially when you see how much rock shops sell these things for. Lessons learned.We ended up so sore from lifting rocks and hammering that we did not even go to the other quarry the next day as we had originally planned to do.When we retire, this place is most definitely on our list of places to come back to!!But next time I am going to be sure we are taking the correct route. Will be going in the morning or when it will be under 80 degrees and has a breeze. And take pain killers before starting our hammering away.WELL WORTH EVERYTHING INVOLVED
This place is awesome. For starters the manager George was really great! He was extremely patient and helpful. My three year old bothered him most of the morning and he was fantastic. He answered all of our questions and made sure that we had an all around excellent experience. We found a tons of fossils. My one suggestion to people would be to go for 4 hours or longer. Any less time than that and you aren’t doing yourself or this place justice. We will be doing a larger family trip next year.
