Seeing dolphins in their natural environment is, in our experience, one of the best ways to truly appreciate the beauty of wildlife and the importance of conserving marine ecosystems.

Thankfully, there are several boat trips available that take you out into the Cornish waters in an effort to see these incredible wild animals.

No company is able to guarantee that you will be able to see dolphins during your boat trip and while dolphins can be found in Cornwall’s coastal waters year-round. However, for the best chance of seeing dolphins, we recommend going out on the waters during the summer months, from June to September since the water is the calmest at this time of year.
