Best shore snorkeling

Im looking for the best shore snorkeling locations in the region. Anywhere from playa del Carmen to Tulum. Can anyone share some good shore snorkeling locations you have found?

And also if you’re going to pay for a boat snorkeling trip to go out to a reef, what’s the best location or reef to go to?

I’ve found some pretty good snorkeling spots right from shore, but always looking for more great spots.

Good snorkeling beaches I’ve found: Xpu-ha, xcacel turtle beach, some of the Akumal bays.

Please share your best snorkeling experiences in the area!
