Sea Trek St. Maarten is a 2 ½ hour tour excursion that runs several times daily. The tour starts with a 5 minute walk from the gangway to the water taxi pier and a 10 minute boat ride out to our staging area. Once on board the Sea Trek dock your guide will give a safety briefing and will answer any questions that you may have. The underwater trek itself takes approximately 20-30 minutes to complete; based on the number of guests participating in that particular tour, 2 separate tours may be made. Each tour will have no more than 10 guests and will have a minimum of 3 Sea Trek staff members with the tour at all times as a safety precaution. If there are 2 groups participating in the tour, while one group is underwater the other guests are offered the opportunity to go for a snorkel while they wait. Once both groups have completed the Sea Trek tour there will be an opportunity to buy photos taken of you on the trek before boarding the boat and getting shuttled back to the cruise ship pier or the main land.Helmet diving feeds continuous air through low pressure lines on the surface down to the Sea Trekker under water. The air pressure inside the helmet keeps the water level right around shoulder height and the majority of the time you won’t even get your hair wet. You climb down a ladder from the Sea Trek dock that reaches 20 feet down to the ocean floor. The track, a loop approximately 300 feet long, takes you past both natural and artificial reefs such as a helicopter, a plane, a submarine, King Neptune and 2 canons salvaged from Fort Amsterdam. You’ll be also invited to interact with some of the local sea creatures along the way. Once back to the beginning of the track loop you climb the ladder back onto the dock while personally lead both up and down the ladder by a guide or safety diver.Min 8 yrs. and able to walk and climb a ladder.
