Khao sok park to Krabi, Thailand

Has anyone travelled from Khao Sok National Park, in Sura Thani province in Thailand, to Ao Phang Nang and Krabi, heading in a southwestern direction? Looking at a map, I see that route 401 theoretically connects with route 4, which circuitiously snakes down to Phang Nnag and Krabi. This is what the map says. I’ve tried The Lonely Planet Thorntree Thailand and nobody has responded to this. Any peeps here in Taiwan know the deal??
Thanks

I will vouch for the existence of route 4 :slight_smile: in fact it is a modern highway. certainly a number of roads connect with it :slight_smile: happy motoring! driving around that area is wonderful.

Tempo Gain,
Thanks for the feedback. Leaving on Friday for 3 weeks. Stoked!
