CAN ANYONE GIVE ME AN APPROXIMATE PRICE FOR A ONE WAY TAXI FROM KRABI TO KHO SOK. THANKS

I am coming to Thailand in June and I am interested in visiting possible new places than I'd normally go to. Typically my favourites on a two or three weeks vacation have been Chang mai, Hua Hin, Udon Thani, Pattaya, spending bout four days to a week in each place.

tried other places like Chang rai, ko samet, phuket, Krabi, few other cities in isaan, Bangkok several times.

I don't care too much for phuket.

Anywhere someone can recommend that they they actually travelled to that they really enjoyed the place.

what are the off beat places in Thailand you have been to? this is my 8th trip to Thailand and I am looking to do something different this time. looking for suggestions.

been to Bangkok, Pattaya, Ayutthaya, Trat, Ko Chang, Hua Hin, Chumphon, Chiang Mai/ Rai and Pai, Phuket, Krabi, Ao Nang, Phi Phi, Samui / Phangan/ Tao.
