We traveled to Costa Rica on vacation with 3 divers and 2 non-divers. We brought our scuba gear in anticipation of getting in some diving. We were staying at a friend’s place in Tamarindo and made a 1 hour drive in each direction to the town of Playas del Coco to dive at the Catalina Islands.
We used Deep Blue Diving right on the main street in town. We boarded a small boat on the beach and were transported to the dive boat anchored a short distance off shore. Our dive master told us that there was a good chance that we would see mantas. When we arrived at the first dive site, we geared up and entered the water. About 10 minutes into the dive, a manta with about a 10 foot wing span swam within just a few feet of us. We were amazed at how unafraid this manta was, and we were really excited to see one so close. Within minutes, we saw several more also very close. We continued to see these mantas throughout the dive. When we got back to the boat, we couldn’t contain our excitement. The dive master told us that since the mantas were here, he would take us to a cleaning station on the next dive.
We arrived at the site and he took us to a large rock where we stationed ourselves and waited. Within a short while, a manta swam up and stopped to be cleaned. Again, this was just a few feet away from us. We spent the entire dive here observing the action. Amazing! The next day, we returned to do some local diving. Visibility was not as good as at the islands and we were disappointed after the previous day, until we spotted a group of 5 eagle rays. That was the highlight of the day.
The boat crew, dive masters, and shop staff were the best. I accidentally left a booty at the shop after rinsing our gear, and the shop mailed it to my home in California at their expense. The 2 hour drive each day was well worth it to dive with Deep Blue Diving.

I used Dive Cabo for diving around the Cabo San Lucas area. The dive shop is located at the marina, and it’s a short walk to the dive boat. They have a large array of rental gear and offer instruction. There's a changing area in the shop and a hot water shower as well!
We dove in an area where there are an abundance of sea lions, a site at Lands End where you can dive in the Pacific Ocean and the Sea of Cortez on the same dive, and a spot that has an underwater sand fall, like a waterfall on land. The diving was relatively shallow and easy, with little current.
The dive guides were very professional and a videographer follows you throughout the dive to provide each diver with a free video at the end of the day. When I return to Cabo, I'll definitely use Dive Cabo again.

I visited the Cayman Islands for a 16 day dive trip in January. On Little Cayman, we chose to stay at the Little Cayman Beach Resort. Reef Divers is the on-site dive operation there. Their custom Newton dive boats leave the dock each morning for a 2 tank dive and again in the afternoon for a third dive. The service here is truely valet diving. The staff and crew load your gear on the boat, set it up, change it over to the second tank, unload it at the end of the day, rinse and clean it, and store it overnight to dry and be ready for the next day. On the boat, they go so far as to have you sit on a bench at the aft, bring your gear to you, assist you to get it on, and then you stand to do a giant stride into the water. No waddling around on deck with your gear on!
They have a large selection of rental gear and offer instruction. The staff is very professional and especially knowledgeable about diving in general, with Little Cayman and Bloody Bay Wall their specialty.
Most of the diving is done at sites along Bloody Bay Wall. It's no wonder it is listed on almost every top 10 list of best dive spots. The diving is phenomenal! The wall is home to many groupers that may follow you throughout the dive, often coming very close, and sometimes rubbing against you.
I just can't say enough about how great this dive operation is. Will return again!

After diving the west side of Roatan, we moved over to the north side of the island to see how diving in this area compared. We used Subway Watersports at Turquoise Bay Resort. The dive operation is very well organized. Each diver has an individual dive locker to stow gear. The gear is set up for you on the boat by the crew each day. The dive masters are professional and informative. The boats are limited to 6 divers and the dive guide. The boats are modern and fast with plenty of space for gear and divers.. Most dive sites are only a short trip from the resort. All dives are guided, but diving your own profile is permitted. Marine life seemed to be less abundant here, most likely due to fewer Marine Park patrols. One day of diving on the south side of the island was included in our dive package. It was well worth the truck ride and we really enjoyed the diving. I like the 2 freshwater showers on the dock. Will return again.
