If you're a photo enthusiast, go UP and visit the towers - you can grab great pictures from the towers (best in the afternoon so the sun won't spoil the photos with the sea). I highly recommend to visit later Casa Batllo (also from Gaudi - 30minutes walking / 15 minutes metro) and enjoy the views of the sagrada familia and the city from the rooftop. If you plan to visit Park Güel do it early in the morning before 1) it's too hot and 2) before you get tired/hungry - I found the park is too far from downtown. Use public transport!
