I would like to visit Khao Luang Cave in Phetchaburi from BKK ...but also I booked a 4-days stay in Koh Tao. I am in doubt of how to plan this 2 trips:
1. Visit Phetchaburi as a day trip from BKK, (by bus) and then reach Koh Tao another day,( by Lompharay bus+ferry from BKK)
2. Get an early bus from BKK to Phetchaburi, visit the cave quickly and then proceed to Chumphon, in order to take the ferry to Koh Tao the next morning
Which variant should I go for? What do you recommend? Any other suggestions?
