We originally scheduled a Saturday morning tour. The weather was a little rainy but we went out hoping the weather would break. Unfortunately the rain just got worse and lightning was in the area, so we ended the tour early (after less than 40 minutes on the water) due to safety. We were given the number of the owner who we texted to see if we could get on a tour for the next morning. They added us to the next mornings tour. We had a little drizzle but other than that it was great weather. The guide was very knowledgeable and great at going at your pace.
The manatees are in the spring area if the river temperatures are too cold, so if the river has warmed up due to days of warm weather in the area they may not be in the spring area. We saw a few manatees (mainly snouts breaching for air) in the spring and around the river. A week before there were a lot more in the spring area. So you will have to temper your manatee expectations based upon the weather. We did see lots of gators, turtles, and birds during our tour so even if you don’t see any manatees it is still worth the trip. My wife and three boys (15 13 & 11) all enjoyed the tour.
We stopped at valentine park before the tour to hit the bathroom. We brought rain gear (ponchos) just in case, but we did not need them. Also bring a camera to get pictures, just be prepared for the camera to get wet. The sit on top kayaks were more stable and I would recommend them for anyone new to kayaking.
