The only reason to go to this beach is the lack of waves, and if you're looking for that you should just continue your journey to Isla mujeres.
Seaweed everywhere, but the worst part is that beach is very small. You also can't go very far into the water (can you anywhere in cancun?) because there's so much activity going on. You know what? the activity is actually the worst part. You will be hounded and harassed everywhere on this tiny beach. Either go to isla mujeres for water you can actually enjoy or playa delphines for a serene beach.
