I have done the same 5-6 times last year. The last two or so hours drive through the mountains is a beautiful drive. But Ranong is not a bad place to stay a night, some good value hotels around and including 'the farmhouse hotel'. And the breakfast/cafe/coffee scene there is active. Very cheap weed in the few local shops. There's a few farmstays on the top of the mountains outside Ranong, but often very quiet, and more accommodations in Lang Suan, which is a huge

hub for distribution of the big heavy fruits grown around the mountains, durian/Jack fruit etc. And if you've not witnessed the breakfast/morning scene in Surat thani city, a 2-3km trail of street vendors along the waters edge there, and a morning market with vendors just laying out their goods on the road from 5am until morning. And I found a stewed pork shop, the same owner serving for over 50 years now, allegedly not a day off sick. There's certificates and newspaper/magazine articles on the walls, and photos with celebrities, and the fella looks at you while chopping the pork, not the pork itself. And he talks to every customer who comes in. I say talks, he shouts at every customer. They're setting up from about 3am everynight, amazing place. Under the CBD hotel. An alternative but similar road trip is to Pedang Besar/Sadao on Malaysian border. Fascinating border towns, like something out of a movie, 'Dusk till Dawn'. But close by, in the national park, the Wang Prachan Boundary post is a soft checkpoint to bounce, but nothing is guaranteed without an agent, which should be arranged regionally in advance. You can meet them as they arrive in the parking area just before the checkpoint if you prefer to drive/arrive yourself.
