We booked our whale watching trip via email (so convenient). Ocean Explorer offers great price, only 15 euro per person and only 10 people on board. We’ve seen few whales, one was swimming next to our boat for a while 🙂 Amazing experience and very friendly staff. We wanted to book dolphin watching trip too but unfortunately there were no dolphins on that day. We will definitely come back to see dolphins next time when we will be visiting Tenerife.
