We went on a Snorkel tour to this reef and saw a breathtaking variety of fish and corals. However, since the waters around the reef are generally a bit choppy (it was a good day, sunny, no winds, clear waters) a number of snorkelers got sea-sick including my daughter who is 15 - some got nauseous not on the boat but while they were in the water. So, first-time snorkelers or boaters should be aware that even on very nice days, the waters can be a bit choppy out there. Two divers who came with us spotted two bull sharks and there were a large number of jelly fish around on the day. It is good to have vinegar spray with you. We spotted people fishing by the edge of the sanctuary, presumably throwing out bait which I found a bit concerning since there were a number of swimmers/snorkelers as well as sharks not far off.

Such a beautiful reef! My only complaint is local boaters and tourist renting boats going through the middle of the reef while divers and people snorkeling are in the water.

June 2022, TS Alex just past and the seas were glassy and calm. As you approach the mooring balls from seaward (to avoid snorkelers) prepare a sturdy mooring line with spring loaded carabiners to tie off to the yellow mooring ball line. Cut the engine and let the tidal current set your boat. When tied drop a "tag line " off the stern and hoist your diver down flag. Always snorkel into the current and if one of your party gets tired the current will drift the diver right back to the boat. Best diving is at or near "high tide" when the clearest water is brought into the reef zone. Try not to touch the coral or sea fans as the environment is fragile and sometimes sharp. Been diving this reef since 1964. When the Gulf Stream is "in" all manner of sea life is found here! Jerry NAUI 2211

We had read great reviews of people's experience at Sombrero Reef, so when we rented a boat for the day in Marathon, off we went.

We had to anchor our boat because all 11 mooring balls were already taken. We snorkeled for about 45 minutes and saw quite a few fish, but not as many as we were anticipating. We have snorkeled in many different places in the US and Carribbean and felt this was a bit underwhelming based on what we had read.

Overall, a good experience, but not a great one.

One word of caution, stay close to your boat because the current can pick up at anytime!

We went to Sombrero Reef while we were staying in the Keys. Very nice reef. The water was smooth and clear on the day that we were there. Lots of fish and a beautiful reef. Robbie and Larry were great! We went out with Capitan Pips snorkeling. Highly recommend asking for Robbie and Larry. They made our trip a lot of fun.

A beautiful reef and so easy to get to by boat. A large variety of fish are easily seen. The current is moderate so easy on swimmers. Here I have seen some of the biggest fish I have seen when snorkeling.
