Yes, I'd say so. The swim through the long dark tunnel to the hidden beach is a unique experience. Kradan beach is very beautiful. Like the Similans, these are popular destinations and will be very busy in peak season. When are you going?
I shall be seeing ko Tao, ko samui marine park, krabi 7 island tour, staying at phi phi (seeing maya bay et all), visiting Pha Nga bay, Similan islands - so I was wondering whats going to be new in Lanta 4 island trip?
just a tunnel swim to a hidden beach? I shall have enough snorkeling, swimming kayaking and "viewing" choices. I do not dive. so whats new for me in Lanta?
