I went on 5/16/12 and it was a great snorkel trip to sombrero reef. Only 5 people were on the boat and so you didn't have to dodge other snorkelers and you could have a section of the reef to yourself. Lots of grouper and angel fish, parrot fish etc. Staff was very friendly and nice and they also do... More

After having experiences with several dive shops in the Florida keys, Tilden's was head and shouders above the rest. They took us to very good dive and snorkel sites, did a great job describing them, and even had 2 tank night dives! In fact, the night dives were especially good because they did a twilight dive follwed by a night... More

We booked with Tilden's because my husband, 14 year old daughter and I wanted to try Snuba. They were very professional and Morgan our guide explained everything before we even got on the boat. . There was another group of Snuba goers as well as snorkelers and scuba divers on the boat and it was pretty crowded. However it was... More

Went with them for a snorkel trip - 15 people. Kind of a crowd for a small boat - 1/2 divers, 1/2 snorkelers. First stop - pretty marginal - not much to see. second stop - Sombrero Reef - FANTASTIC. That said, I wouldn't go with these guys again. We had a wetsuit reserved, but decided to buy one instead.... More

Nothing but praise for Tilden's Scuba Center. A completely "pro" operation interested in safety, hospitality and customer enjoyment. I took the refresher scuba course (two years since my last dive). The instructor (Don) had me all checked out and thoroughly ready for my two dives included in the package. On the boat, complete briefings, hospitality touches and organized entries and... More

I've been to the Keys several times in the last couple of years, and have been done all of my diving with Tilden's team out of Marathon, and I wouldn't think about going with anyone else. The captains, dive masters and shore crew are all friendly and knowledgeable, and our safety and making sure that we enjoy our dives are... More

I was in Marathon and wanted to get a couple of dives in while I was there. I went to Tilden's and they had a couple of trips available but the time did not match my schedule. I left my name and number and 3 hours later they called and had arranged a trip with some other divers that wanted... More

This was the firs ttime our 11 and 13 yr old dove in the Keys and the first time the 4 of us dove together as a family. First site was Sombero Reef. Viz. was about 25' on average with a slight "milkiness" in the water. Reef life was plentiful. Second dive site was my choice and I suggested the... More

Picked them because they were the only dive shop diving the Thunderbolt wreck the week I was there. They're friendly and can help out if you ask for it, but you're expected to take care of yourself. You're asked to be back on the boat at a certain time, but generally allowed 50-60 min in the water. Dive Master in... More
