As we were staying in Puerto de Santiago we were often in Los Gigantes and came arross lots of signs and sales people offering boat trips into the bay area for whale and dolphin spotting excursions. We decided to wait until the last day of our holiday to go on the trip and wish we had booked for longer than the 2 hours. The tip was amazing. It was the cheapest on offer from the resort and from what we could see with the other boat trips doing the same, ours was the best as well. We spent a good hour out at sea hunting down packs of dolphins and whales and got to see lots of different ones and some were even chasing the boat. After the initial dolphin watching we sailed to Masca bay which is around the bay from Los Gigantes. We stopped in the bay and people were given the opportunity to jump into the clear waters and swim with all kinds of marine life and we were even given a free soft or alcoholic drink and snacks to eat whilst we were there.
For 15euros each for a 2 hour boat trip, packed with so much to do and free drinks and snacks it is worth every penny and possibly even more, we gave them a tip upon leaving the boat as it was such good value.
