The Similan Islands National Park includes more than just the Similan Islands.
It includes both Koh Bon, which is well known for Manta sightings, and Koh Tachai too.
Koh Tachai is known for it’s underwater pinnacle that is teeming with life, and is a good place to spot large schools and occasional sightings of the big stuff like Mantas and Whalesharks.
Just north of the Similan National Park is the Surin Islands national park, which includes my favourite dive site, Richelieu Rock.
There are a couple of these running from Khao Lak. They leave harbour at between 8am and 9am, take approximately 1.5 hours to get to the dive site, give you 2 dives, lunch on board, and 1.5 hours steaming back.
One of them leaves from Ban Nam Kem Pier and gets to both Richelieu Rock and the Surin Islands on scheduled days. The other leaves from Tap Lamu pier and goes to the Similan Islands
They are not as bouncy as the speedboats, which means they are better suited to people who are less mobile.
You generally get back to your hotel around 5.30 pm, in time for dinner and to check out the local night life.
It’s a great option for:
There are a few companies running speed boats to the dive sites. These generally leave the pier (either from Tap Lamu or further north at Ban Nam Kem) at around 8 am.
They take between 1 hour 15 minutes and 1 hour 25 minutes to reach the dive-site, depending on where they are going. Just as with the catamarans, they give you 2 dives with lunch in between, and then return home. They are usually home before 4 pm, meaning it’s a short day.
That’s good news if you’ve left family or friends on the beach while you go out for the day, and it’s a great move if you’re at an ‘all-inclusive’ resort!
They can be a bit a bumpy so they’re not suitable for people with back problems. However, they’re also quite exciting, and very efficient in terms of travel time.
They go to the same sites as the catamarans, and they also get to Richelieu Rock.
*If you have either back or mobility problems, choose the catamarans.
Diving Insurance is mandatory when diving in the Similan or Surin National Parks.
For many people their travel insurance covers diving, but if not, and you don’t have specialist diving insurance, we can help. We can arrange daily, weekly or annual insurance with a UK insurance company to cover the diving that you want to do.
