Even though I wasn't on Koh Lanta for very long, it seems that the nightlife is pretty good. I mean it is calm compared to the other islands I visited, but if you look around, a good time is easily found.
Up and down the main road are plenty of bars offering various "specials" to attract people passing by. For example, I don't know how many signs along the road for the Opium bar. Although the name intriged me I actually never got a chance to check it out, maybe next time. Other were offering anything from movies to free or cheap drinks, just for coming to visit.
****UPDATE****I saw the same bars on the street once again, went to a few of them, but still never got a chance to go into the Opium Bar....hehe.
Since Ko Lanta is relatively untouched it is a unique experience to ride a motorbike across the island. The main road has been paved only recently, in the southern part of the island, there are still dirt roads.
If you go south, go also across the island to the east coast (the beaches are all on the west coast); there is a nice viewing point and you can visit the capital of Lanta which is a traditional muslim town with chinese influence.
This is quite unique since most areas of Thailand are buddhist; the southern provinces close to the Malaysian border are muslim.
If you go south by motorbike you'll reach some area where there are some treks leading into the jungle.
There you can see some great flora: big trees and plants, you see also some birds and reptiles. Really a good adventure.
Stay on the footpaths and try not to get lost!
This is my favorite Sunset pic shot. I consider it as off the beaten path though as the place is silence in between the 2 side beachs.
I loveeeee it.
