Plenty of beachbreak peaks including a short hollow right and a longer sectiony left. Rotonda is usually the best, but it gets crowded with Catalan surfers when on.
Be respectful to the local riders as crowding is increasingly causing problems. Parking is normally okay but beware of rip-offs. Surfshop in Masnou.
You take the A-19 and get off at exit Montgrat. As you exit, you will see the wave in front of you. You just have to turn around, go down to the barrier and turn right. You will pass under the road and get directly to the water.
