Getting around Ko Lanta is best by renting a motorcycle, it's really cheap, but i cant remember the price. Otherwise, if you're not gonna be on the road alot and would prefer to stay mainly at your resort, a tuk tuk is always readily available to ferry you to and fro. Cost from Pra Ae beach to Ban Saladan is 50 Bahts( example ) depending on the distance.
If you alight krabi town from krabi airport, you'll be able to get a transfer from krabi town to ko lanta, either by ferry or by minivan and then car ferry. Ferries dont operate until mid or late november from krabi town i think. I enquired about direct ferry, and was told that it was not operating yet. ( 1st week of november ).
Minivan cum car ferry cost 350 Bht per way....and its a 2 hr trip. you'll be on the car ferry twice. Once is from krabi mainland to ko lanta noi, followed by the 2nd trip from lanta noi to lanta yai. Just short ferry rides.
For those who prefer direct ferry, or going to Ko Jum, you can take a ferry from Aonang, which by November, is in operation.
Exchange mini bus at Trang if you are from Hat Yai. So the mini bus go directly from Trang to Ko Lanta.
You need no get out of the Mini bus unless if you feel like chicken roasted!! hhaha
The bus will drop u off to the chalet that u interest to stay.
The ferry from/to Krabi varies in the time it takes. We went for a day trip and the ferry there only took an hour and a half and the one back took over 2 hours. You can buy drinks on the boat though. As you can see from the photo, some of the boats are a bit strange in that they are a bit like a living room.....for very small people!)
It cost 200 bht per person each way (kids went free). Times we travelled were 8.00am leaving Lanta and 1.30pm returning (I think that was the last boat of the day!).
Beware though that there is a new ferry terminal at Krabi and older guidebooks (such as mine!) tell you that you arrive in the town, and you don't anymore, you have to get a bus/taxi which costs about 20 bht from the terminal to the town.
We rented a motorcycle to do a little bit of traveling on this island. It worked out well except for the fact the all the roads are dirt and by the time you get to your final destination, your mouth is full of the stuff. blah
Well, I did not get on one of these babies, but I'm sure I could (if I had enough money, that is) :-p
Getting onto the island is best done from Krabi, from there you have to take two car ferries to get to Lanta Yai, buses are easy enough to book from Krabi. It's a 70km trip.
To get to Koh Lanta you can take the plane to Krabi airport and from there a taxi... But you have to cross the sea by a car ferry two times.....
