I waited 6 years to do the Shell Key Preserve tour with Coastal Kayak and I regret waiting so long. The tour was beautiful. Lots of dolphins, sea life, super cool mangroves, and Shell Key was breathtaking. The staff was so friendly upon arrival and our guide, Daniel, was awesome. He was so patient and so knowledgeable. I definitely recommend Coastal Kayak and we will definitely not wait so long to return for another trip!!
