Really cost effective way to experience the National Marine Park

A great cost effective way to see the National Marine Park and have a few hours on a tropical beach. The water was warm and the sand soft (unlike the beach at my hotel) and this was my only opportunity for a sea swim. Everything ran to time and safety precautions were in place.

Many boats sailing to one main location with large numbers of passengers to enjoy 20 min activities, climbing lots of stairs and

There are many tours to the Marine Park but this one was one of the lowest cost. Originally we were booked on the Red Baron (a substantially better equipped vessel) with fewer passengers but due to high waves it was cancelled with 24 hour notice and we were asked if this tour was of interest to us. It was the last vessel available for that day so we took it. It was less than half the price of the Red Baron. We were about 50-60 passengers in all. So, this tour leaves Nathon pier at 8:30 am and sails for about 90-120 minutes (depending on waves) to reach a passage in the islands where it moors. The motoring over was tough on some passengers with a few heaving over the rail. We did fine having taken seasickness pills 30 min before departure and keeping an eye on the horizon throughout. Once at the marine park we were shuttled by long boat to the island for a strenuous ~30 min steep hike to a windy viewing platform for shots of the surrounding islands. It was pretty. We descended to find three little monkeys up a tree eating fresh shoots. Without a powerful telephoto you'll see little. We then waited an hour before being shuttled to the other side of the bay where we hiked up precipitously steep sets of stairs to view a lake in the middle of the island. In actuality it is a body of salt water about 300 meters in diameter fed through cracks and tunnels in the karst formations, that access the sea. You cannot swim here as much as you'd like to jump the fence and cool off in the clear waters. Authorities should definitely make a water access for swimmers by just adding a staircase down 2 meters to water level. Of course this would mean supervising the area and they are not interested in paying someone to do it. After hiking back up and back down we are back at a busy little beach for swimming or snorkeling. Snorkeling here will result in nothing to see so don't bother. After another 30 minutes or so we are asked if we want to do the 20 min kayaking along the island back to a beach where group one had originally started, to return the kayaks. No idea where the caves are unless they mean the paddle throughs in the overhangs. Not caves; just short narrow passages between the island and the sea. We were then hustled out of the water to wait 15 min for the long boat to take us to the big boat for the return voyage. Once on the boat we lined up for a hot buffet of chicken curry with side dishes, which was actually quite good. Our Thai lady guide was helpful on the boat making sure things went off as planned and keeping wobbling passengers from falling or dropping their meals. Her English was ok. Once fed the boat shifted into high gear and made a B-line for Nathon, arriving there in just under two hours. nnNow the important summary and tour comments: As mentioned this tour was one of the lowest priced public sailings to the islands so the seven of us in our party didn't have high expectations. But let me give you my impressions as a mature seasoned traveller. From pier to pier it took just under 8 hours, 4 of which were sailing. That leaves precious little time to enjoy what the islands have to offer both from a snorkeling and kayaking point of view but also to just explore. Additionally because the group is large, sharing gear and kayaks is necessary cutting in half the time we had to enjoy them. Twenty minutes to kayak and an hour total to snorkel fishless sandy bays is poor value regardless of what you pay. Negotiating the islands' floating piers made of plastic interlocking pontoons, buckling and heaving in the surf requires balance and good footing. Many people required assistance to keep from taking an unintended dip. Why there is no permanent wooden or cement pier on these heavily used beach accesses is beyond me. And why all tour boats go to the same islands when there are 42 of them is also a mystery. Sure, the park headquarters are here, and whatever tourist infrastructure has been built is here, but again why not offer different itineraries to other locations to reduce bottlenecking and overuse? Snorkeling elsewhere in the islands would definitely have been great. There is no question that in Thailand the amount of money pulled in by the thousands of tourists every week to these islands would be more than enough at their wages to expand the meagre infrastructure and offer more variety. Over many years it doesn't change! Why? Because so many tourists are satisfied with what they're getting and write glowing comments for mediocre tours. Writing detailed accurate and helpful reports is not about hurting someone's feelings or being polite, folks! It's about spending a large amount of money for the average Thai and getting good value. Not true? Well, where was the nature guide to explain the history or geography of the area? Where is the exhibit area or interactive interpretation center? It can be built right beside the park headquarters! Does anyone know what kind of monkey we saw? No? Well no wonder. The people from the boat and in the area also had no idea. Why are we all herded to the same venues day after day, week after week, year after year? Because few people give them thoughtful feedback that would affect change... maybe... I say maybe because how the money we give tour companies is divided up may be the key to why nothing seems to be improving.nnLast wordnFor a day tripper wanting to catch a glimpse and a selfie of this beautiful island chain, what's on offer likely feeds the need. Been there, done that. But almost all visitors based on reviews from multiple sources say the same thing about this tour: long sail; short time activities; terrible snorkeling; strenuous climbs; beautiful viewpoint panorama; decent food; no guides much less information about the islands; and a lot of people in one area.nThis is a three star tour... no more. It's a mass production cost cutting exercise in pushing through the maximum number of passengers on a single itinerary with limited liability.nA four star tour is only available privately at 5-10 times the price.

Rushed visit to the park

This trip could be a good value depending on your expectations. We traveled Sept 2022 and booked a few days in advance. We enjoyed most of the trip but if you want to kayak and snorkel review the time itinerary and note you will have only 20 or 30 minutes to do each activity which was not enough. We also were disappointed that the group size was 100-120 people not 50 as listed and the tour was not English only. Itu2019s more of island transport with provided food and kayak and snorkels, thereu2019s not much tour on the sense that itu2019s not really guided and the staff doesnu2019t do much to explain the park, history, wildlife etc.. The lunch was pretty good (chicken and rice and salad) and they provided one bottle of water and some soda and snacks. Thereu2019s an option to buy water in the park before the optional, tough and worthwhile hike up to the observation point at the first stop. We were very rushed at the second stop trying to kayak, hike to the lagoon and snorkel all in 90 min or so. We also found the snorkels were moldy and tried to wash them off but it was a bit gross. The snorkel spot has some fish but with wind and waves and no large reef itu2019s not ideal snorkeling. Hotel pick up was smooth. Next time Iu2019ll opt for a speedboat and smaller tour group to visit the marine park.

Sailing, snorkeling, kayaking & climbing Day Out

Discovering the view of the 42 islands of the marine park was great and so was the snorkeling. At the second island, the view of the lagoon ringed by granite cliffs separated from the sea was idyllic. Only regret was not taking the kayaking package, I heard that the cave portion was super cooling and even the kids on this trip loved it.

Great experience

Great experience and well organized staff who made our trip super. The marine park is worth a visit!

hannashvtApril 15, 2022

I am highly recommend this trip!

I was enjoying everything on this trip - we went to Marine Park and had time for take a look on beautiful view from the top, also they make everything very comfortable - in each destination we always had time to make a picture, enjoy and never feel in rush. Thanks for wonderful experience! I am highly recommend this trip!

Great trip. Beautiful scenery

The one-way boat trip takes more than 1 hour. It is recommended to take seasickness medicine. The coach and the staff on board are very nice. I was worried that I was not good at swimming and I was a little afraid of kayaking and snorkeling. But after the explanation and demonstration of the foreign coach, the kayaking is really fun. The staff will also lead the team and follow to ensure the safety of the team members. There were a little wind and waves, so the clearness of the water was poor, so there was no snorkeling. nnA little regret.

saving time and money well

The event itself is very picturesque, exciting, interesting. Loved the kayaking and lookout. But the snorkeling was not very good. Few fish are muddy water.

Christoph19811755September 20, 2020

highly recommended

There are cocoons, bananas, sodas, and coffee on the boat. If you are in a canoe, you will also have a small waterproof bag. The lunch is good. In the situation, the stairs to climb to the highest point of Antong are steep and difficult to walk but the scenery above is beautiful. nnThe summary is a great experience!

Nick01121965July 17, 2020

A great day out to Marine Park

Friendly staff, pleasant boat trip, fun-filled day. Our only gripe is the shallow coral that cut our thighs, so (other amateur snorkellers) take notes! Kayaking on a calm sea wasn't too difficult for us first-timers. Money was worthwhile and more.

Senza infamia, nu00e9 lodi

Escursione molto turistica, da vedere francamente c'u00e8 ben poco. L'organizzazione u00e8 ok, ma con tanta gente che non permette di godersi la pace del mare e delle isolette incontaminate.nn
