Fun and relaxing soak. Did the swimming option. Not sure how much you would see snorkeling. Water is very warm but not hot. Get to float, bob or paddle around. You wait outside until your time slot. We had nice day - in the winter I’d wait in my car until very close to time. Once they open the door, you enter a long narrow hallwayThere are 4-5 small changing booths, and ~ 30 ish small lockers. Would minimize what you bring in with you. Checkin, get the rules explained, pick out a life vest (possibly wet from prior time slot) and walk out to the floating dock. Climb down pool ladder into very warm comforting water. There are 2 small areas off the dock set up with benches where you can sit in the water (think hot tub) or stand. When we were there everyone bobbed or floated in their groups. Had space to move around some. Overall cool experience I would recommend if you are in area. I would go again

The Crater is always great to visit and the whole property is just gorgeous. However, we will now be staying at an Airbnb, and just visiting to soak or dive for the day. Between the high room rates and the fact that there’s no breakfast options, and no place to even get a cup of coffee in the morning—it’s not worth it to stay. No free coffee in the lobby, no restaurant coffee. The cute little Milk House looks amazing, but says it opens at 7 & a bunch of froze our butts off outside waiting til 7:15 with zero activity in the building. Front desk said they decided to open at 8 , but there were no signs and not updated online.

I was a bit skeptical of going since we did this late October and at the time of our visit it was in the low 50’s. But, I was pleasantly surprised it surpassed my expectations. The water was 93 degrees and clear as can be. Our group ages ranged from a 1 year old, 10 yr, 30’s, 60’s & 70’s. Everyone had a fabulous time. My skin was sooo soft afterwards. I’m glad we went early since you do have to wear life preservers and we were fortunate to be the first to use so they were dry. Bring your own towels, limited (4) changing rooms.

It was really amazing to float in a warm water spring in a natural crater, and for that I give it four stars. However, there are definitely ways the experience could be improved. First, I arrived at night, and there was no signage directing you to the crater until you were right next to it, and even then it was hard to see at night and ambiguous in its direction. The actual entrance had no signage at all, except maybe something small right on the door. My main issue with the swim itself was the requirement that everyone wear life jackets. I understand they are trying to limit liability, but there are lots of places that the public can swim that don’t require life jackets. I float like a cork even without a life jacket, and having to wear the jacket made the whole experience less pleasant. The other thing that could be improved is the lighting. The harsh lights glaring down from above don’t make for a very nice ambiance. I kept imagining how nice it would be if there were hidden lights recessed above one of the rock strata that make up the walls.

We loved it ! Bring towels they do not provide them and your going to be cold! The crater is clean and well kept . The lockers are small and no locks you won’t need them . The dressing rooms are small but efficient and clean. The host was cheerful and informative .

Just recently went to The Crater and hands down, Dave is the best employee that works there! Love his sense of humor and his willingness to give us a hand if needed. He shares historical information about The Crater in a fun and interesting way. We highly recommend going to The Crater and saying "hi" to Dave!

I brought my two children, mom and husband for an hour dip and we made every second count. It was a little confusing when we first arrived since we didn’t know if we should wait outside or come inside and let them know we were there. David the attendant came out and let us know how everything was and to come at our exact time for a smooth transition from group to group. If there was signage outside that would have helped so he wouldn’t have to explain but it was greatly apreeciated. Come pre dressed in swim clothes, bring a towel and flip flops, and your change of clothes to maximize the visit. We came pre dressed, put our belongings on the white shelf, grabbed life jackets and got right in. The minerals make your skin feel slippery smooth and everybody felt so calm the rest of the day. The crater was clear blue to the bottom and a perfect 94 degrees. We will certainly stop by again!

Dave H was a fantastic scuba instructor. I did my open water certification dives with him and he made the experience feel very safe and fun. He told a lot of jokes and allowed me to take a minute whenever I needed to think through a task, so I never felt rushed.

They allow young swimmers and they provide life jackets. However, you can bring your own jackets. The water is very warm and swimming in a cave is cool Don't bother paying for the snorkel adventure for kids as there are no masks that fit them; just bring their own goggles and snorkel if they are old enough to snorkel. The snorkles for adults looked haggard I suggest you just bring your own. The water is very dark so there is nothing to see unless you have scuba divers surfacing.

After reading a number of reviews, I wasn’t sure of what to expect. I have to say, I was pleasantly surprised! This was a great experience! We went at the 8:00 am session to avoid divers, there was only 2, because some reviews said they were a problem. Others claimed it was crowded, but this session was sold out at 24 and it wasn’t crowded at all. The water was the perfect temperature and the required life vest was perfect rather than treading water for 40 minutes. Some people mentioned the dressing rooms were too small, there are 4 and they are large enough for two people. We came in our suits and changed afterwards. Only challenge was the ladders into the pool are a bit narrow and not the easiest for someone in their 60s but doable. The girl working the day of our visit was very pleasant and helpful and at the halfway mark she came in and told us the history of the crater. I would definitely do this again!
