This spring is stunning! My husband and I visited in the evening and had the whole place to ourselves. It was kind of real to look at. Definitely suggest a visit but it probably wont' take more than a half hour, depending on how busy it is.

Stopped in randomly on our way home from Pictured Rocks, happy we did. Great opportunity for the toddlers in our group to see plenty of fish, learn about the springs and help wheel the observation raft out and back to the dock. Interesting science and history experience. Plenty of parking & restrooms. Small gift shop. Overall great experience and would recommend

Our daughter's speech therapist told us about this place. We stopped here on our way up to Munising. I wish we'd have had time to explore the park but we just did the boat part. It was really neat to see how beautiful and clear the water is. You can even see the spring bubbling down below in the water! We all enjoyed this stop.

Put this place on your to visit list! It is worth the stop and looks exactly like the pictures! The water is exactly that blue and stunning! We had to wait a little bit to ride the boat but it was shaded the entire time we were waiting and a generally pleasant experience. For those of you who collect pressed pennies, bring your change with! We will be back again!

We arrived at 8am when the park opened and stayed all of 15-20 mins. Only one other family there. We rode the ferry twice. It was beautiful and the water was crystal clear. Pictures do not do justice. If you’re in the area, I would stop by quick.

We waited about 45 minutes (late Sunday morning visit) but worth it for the experience. Enjoyed an interesting discussion with employee Alec on all things about the site. Time on boat maybe 15 minutes. Wonderful views. Great value and experience!

Have stopped here numerous times and always find it an amazing experience to see water clear enough to view the bottom at 42 ft and watch the sand bubble as 10,000 gallons of water per minute bubble up. It is also a treat to see the lake trout and other fish that swim upstream from the lake. I particularly made the stop to share the experience with my 17 year old grandson, who enjoyed the viewing raft and the Big Spring as well as the well stocked gift shop.

Great sight to take in! Dirt cheap! Buy an $11 day pass for Michigan Parks (per vehicle)is all it is! No extra charge for the raft ride. Raft is self-operated by visitors. Runs on a cable and you turn the big wheel to move it across the spring. Observation view on bottom of raft was cool to view w/o glare to bottom of spring, see fish and how the spring bubbles up the sand. Really cool! Short and interesting natural wonder! Nice gift shop too!

Very worth the visit! The clear water and seeing the active spring through the clear bottom of the raft was really cool! A great find in our beautiful State! Go early, it gets busy even on bad weather days!
