We came to Crystal River specifically to swim with the manatees. We were also staying at the Plantation Inn, which does offer packages.
We were there mid July 2017. If you are staying at the Plantation Inn, you can't beat the convenience and location of this dive shop, which is right next to the inn and also on the water.
So the manatee watching experience was pretty good. We were on the first trip of the day. It was a nice ride out to the viewing area, which turned out to be in the waterways/canals behind the homes on Crystal River. After the captain scoped out the scene with the other boat captains, i.e. where the manatees have been sighted, we moved in to our place in line and got into the water. I'd say they were at least 6 other boats vying for prime viewing spots.
All the boats and crews did a good job of keeping things from getting chaotic, and our crew was no exception. Not only did we swim with manatee, but we got up close and personal with a baby manatee. The baby was the size of a large adult hog. The adult manatees, quite a bit larger. Very peaceful and docile.
One thing I noticed, is that many other groups were swimming with noodles. I asked about why we were not using them, and it was because the wet suits used at Plantation are a thicker variety, and the extra flotation is not required. So that's a plus for a warmer experience, as the spring fed river water can be chilly... But if you want to swim down in that thicker wet suit, well you better have good lungs and a better kick.
On the way back we stopped for a swim at Hunter Spring. It was a nice stop, as were had more room to move around. In the canals it was rather cramped, but this was quite nice.
Oh, and can be an observer on the boat, if you are not one for the water. It's still going to cost you something, but not as much as the swim with the manatee experience (since you won't be needing the wet suit, mask and snorkel). Which reminds me, no fins as they really kick up the sediment which would make viewing a drag. Even without the fins, the soft bottom get stirred up quite a bit at times.
The dive shop itself is on the small side, but seems to have all the essentials, and few non-essentials (manatee plush toys, t-shirt, etc.) too.
Bottom line: My bottom line is going to a pro tip, which will come as no surprise to anyone living in this area. You can easily do you own manatee viewing, and save a bit of money. There are many public areas to access the water, either with kayak, inner tube, or even stand-up paddle board. Now there are best times of the year for this, so do your research. If we were to return to the area, we'd Airbnd a place to stay, maybe a place with SUPs and/or tubes, and enjoy the area on our own.
PS. I see all the other 5 star reviews, but I don't think I have enough to go on to say that it's "As good as it gets." I don't know what other tours might offer, and I have no cost data. That being said, we have no complaints about the experience. As mentioned, if your staying at the inn, you can't beat the location.
