After slots of reading we are set on the Ko Kradan island for few days.
But still looking for one more island to visit in this area where one could enjoy the nature, walks, kayaking, not the crowds. Can you help me please?
I can't remember whether an earlier message from you said you were going before Tigerline kicks in. If so, Ngai or Muk are best choices. Muk has the most contrast to Kradan.
If after Tigerline has started, Ko Libong is another alternative. Real nice island with minimal tourist impact - I think all 3 resorts (Libong Beach, Le Dugon, Nature Resort) have kayaks - Nature has a rep for higher prices than the others.
Libong is a bit of a hassle if Tigerline is not running - you will have to go back to Trang and out to Hat Yao pier.
Laoliang is next stop after Hat Yao pier on Tigerline (although you can spend some time at the pier swapping Tigerline boats if one is not on time) and has good snorkelling, great nature, climbing, kayaks - no walks.
Big hassle to reach from Kradan if Tigerline aint running.
If you are heading back towards Krabi, Ko Jum is a nice possibility.
