A walk to Barceloneta is a all year long wonderful thing to do in Barcelona.This is a beautiful walk for the morning, starting at Rambla del raval, maybe have a stop at the terrace of Barcelo Raval Hotel and enjoy an amazing view, breakfast at La Monroe, will be an excellent choice, just behind Barcelo Raval Hotel.
Keep walking to Av drassaness till Mirador De Colon, and from here just take Paseo de Colon, i recomend to walk by the sea side, i do all the time and i love it, at the end you will take Paseo Juan the borbon till you get to the beach area, now it´s your turn, many beautiful chiringuitos are waiting for you but you should get till the very end, W hotel, have a coffee on the last terrace, by the palms trees, on the green chairs, drinks are not cheap but having a coffee sitting there with that view, believe me…. it is worth it!!!
Make you way back exploring Barceloneta…. get lost and look for Plaza del Poeta Bosca and Plaza de la Barceloneta on your way back, if you feel like a nice paella, the best places for me are La Ostia Taverna Gastronomica @ plaza de la barceloneta and La Mar Salada at the end of Paseo Juan de Borbon.
