Detective Pux here, at your service! I've heard you're curious about where you can see large sea turtles in Spain. Well, let me tell you, my friend, there's no need to go on a wild goose chase. I've got the answer for you right here.

First things first, let's get one thing straight - Spain is not known for its large sea turtle population. If you're looking for a place to witness a massive migration of these majestic creatures, then you're better off heading over to Mexico or Costa Rica.

However, if you're still adamant about finding these elusive turtles in Spain, there is still hope for you. The only place you're going to find them is in the Canary Islands. That's right, folks, the beautiful archipelago located off the coast of West Africa is your best bet.

Now, I know what you're thinking. Detective Pux, are you sure about this? You're telling me that in a country surrounded by the Mediterranean Sea and the Atlantic Ocean, the only place I can find large sea turtles is in a group of islands? Well, my dear friend, that's exactly what I'm saying.

The Canary Islands are home to two species of sea turtles: the loggerhead turtle and the green turtle. These turtles can be found swimming in the waters surrounding the islands, and if you're lucky, you may even spot them laying their eggs on the beaches.

If you're looking to catch a glimpse of these turtles, I suggest you head over to Fuerteventura or Lanzarote. These islands have some of the best spots for turtle watching. The beaches of Cofete, Playa Blanca, and Papagayo are just a few examples of where you can spot these magnificent creatures.

But let me warn you, my friend, these turtles are not easy to spot. They are masters of disguise and can easily blend into their surroundings. So, you'll have to keep your eyes peeled and be patient. But trust me, the reward of seeing one of these turtles in their natural habitat is worth the effort.

Now, if you're planning a trip to the Canary Islands just to see these turtles, then let me tell you, that's not the best idea. The islands have so much more to offer than just sea turtles. From the stunning volcanic landscapes to the beautiful beaches, there's something for everyone.

And if you do happen to spot a sea turtle, make sure you don't disturb them. These creatures are protected by law, and any interference with their natural habitat can result in hefty fines.

In conclusion, my dear friend, if you're looking to see large sea turtles in Spain, then your best bet is to head over to the Canary Islands. While they may not be as plentiful as they are in other parts of the world, they're still a sight to behold. Just remember to be patient and respectful of these magnificent creatures. Happy turtle watching!
