Tubbataha March 28 - April 4, 2020




Imagine yourself surrounded by pristine hard corals as far as the eyes can see, thousands and thousands of reef fish, cruising sharks and rays, swimming turtles and drop offs into oblivion.

What is Tubbataha?
Tubbataha is a spectacular remote series of reefs in the Philippines. This reef is so unique that it has been named an UNESCO World Heritage Site, and is only open to divers a few months each year.

We will explore Tubbataha onboard the luxury liveaboard, the Azores. This 107 ft yacht offers staterooms for 16 divers, with a large dive deck, camera table, galley, salon, and a hot tub on the deck.

Munising Bay September 14-16 2018

Join us for a fun-filled weekend on the southern shores of Lake Superior!

September 14-16, we will be in Munising, Michigan - our MOST POPULAR local trip destination!

Why is it so popular?
Munising sits in a bay, and it is protected from the wind on most days...which makes the diving exceptionally easy. The shipwrecks around Munising range in depth from 25ft to about 90ft. And the best thing about diving in Lake Superior - no zebra mussels! You can actually still see the paint on certain parts of the shipwrecks.

What else is there to do around Munising?
Plenty! Munising offers many other topside attractions- waterfalls, jet boat rides, glass bottom boat tours, kayaking, hiking, ATV trails , and the Great Lakes Shipwreck Museum. And did I mention Piggy Fries?

Why go in September?
Even though the nights are cooler, the water temperatures in the bay are still at their peak, and the autumn colors are breathtaking!
