Koh Bida Nai

Koh Bida Nai

A Stunning Island With Lots To See

In the interest of variety we don’t dive Koh Bida Nai very often, it’s very similar to it’s sister island Koh Bida Nok which we consider to be a better dive site. It was on a par but since we lost the beautiful staghorn fields to coral bleaching it’s lost a little of it’s lustre.

Still it’s an interesting dive site with lots of hard corals, boulders and swim throughs. The swim through at the south west corner is particular nice, it forms an almost perfect triangle and always has a school of yellow snapper and occasionally a ribbon eel will make it home. On the sand around the deeper part of the swim through we can find kuhl’s stingrays and cuttlefish, on the shallower exit we sometimes find hawksbill turtles and yellow lipped banded sea kraits.

A nice pinnacle covered in whip and hard corals sits at the south east corner and usually attracts a school of chevron barracuda as well bluefin and golden trevally’s. There’s also a chance of a leopard shark and if you’re really lucky any passing whale sharks seem to favour this area. Look closely at the whip corals and you may find whip coral shrimps and gobies.

A hard coral garden on the west side attracts lots of reef fish including the saddleback clownfish which is quite rare for this area. Blacktip reef sharks are also usually found skimming over the corals in the very shallow areas and make a nice end to the dive. Overall a nice dive site that gets a little less attention than it’s more attractive sister. We can’t always promise to visit this site but it’s a nice change when we do. We visit Phi Phi on Wednesday, Thursday, Saturday and Sunday.

Surin Island Dive Site Koh Tachai

Koh Tachai Pinnacle

Koh Tachai is a picture postcard tropical island with lush greenery and white sand beaches situated 20km north of Koh Bon and the Similan Island National Park. Underwater it's even more spectacular, huge granite boulders, healthy corals and tonnes of fish. A couple of mooring buoys is all you will see above the surface, the top of the dome shaped pinnacle is at 12m and falls away to 45m on the deepest side. The site is usually exposed to strong currents so you'll make your descent and ascent on of these buoys that will safely guide you down to an area of shelter from the current. On the west side you will find large boulders and swim-throughs and on the east there's gardens of sea whips [...]

Octopus Are a Common Sighting In Phuket Diving Rare & Peculiar Critters

How Does An Octopus Change Colour?

Dazzling colour changes and perfect camouflage make octopus a favourite with everybody diving in Phuket but how do they perform this magic trick, well it's not mirrors, sorcery or witchcraft it's a complex combination of muscle, nerves, brain and skin pigments. By far the most common octopus we see when diving in Phuket is the day octopus (octopus cyanea) so we'll base our facts around this very convenient creature (we don't do night dives). That's what the cells are called, octopus have thousands of different colour chromataphores to every square inch of skin. Think of them as tiny balloons filled with coloured ink. The 'ink balloons' on most octopus come in black, brown, red, or [...]

Yellow Snapper At Phi Phi Amazing Local Dives

A Great Days Diving At Phi Phi And Shark Point

Grey skies and a humid atmosphere greeted us as we boarded our dive boat in Chalong but thankfully there was no wind or waves on the way to Phi Phi and a comfortable journey ensued with the hope of better conditions under the waves than we had above. We weren't to be disappointed, visibility in the bay at Koh Bida Nok was excellent and a quick swim up into the shallows brought a brief glimpse of a couple of blacktip reef sharks cruising around in less than 3m of water. Heading deeper we found a hawksbill turtle munching away on bubble corals and we've yet to reach 5m depth or 5 minutes into the dive! The 'finger' on the west side of the bay was blanketed with a large school of [...]

Hawksbill Sea Turtle Descending from the surface Rare & Peculiar Critters

Meet the Hawksbills of Phi Phi

Sea turtles make for lovely encounters underwater. In Phuket day trip destinations, the species you are most likely to see while diving is the Hawksbill turtle. The name Hawksbill comes from the narrow pointed beak that resembles a bird’s beak. An other distinctive feature is the overlapping scutes pattern on the carapace, giving serrated edges to the upper shell. Hawksbill turtles can grow up to about 115cm in shell length and nearly 70kg in weight. You may encounter Hawksbills in numerous Phuket diving destinations, with very good chances in dive sites around Koh Phi Phi Ley, Koh Bida Nok and Koh Bida Nai. Like other species of sea turtles, the Hawksbill is not bothered muc [...]
