How much does a Thailand elephant sanctuary tour cost?

On ThaiEleHub, Living Green Chiang Mai half-days are ฿1,400 per adult and Big Boy half-days are ฿1,500. Living Green’s child price for ages 4–8 is ฿1,000. You pay 25% per person online, so the adult deposit on a ฿1,400 half-day is ฿350 and on a ฿1,500 half-day is ฿375. Full-day Chiang Mai fares run from ฿1,700 to ฿2,000.

Bangkok half-days to Chonburi are ฿1,900 per adult. Pattaya half-days are ฿1,800. The online deposit there is ฿800 per guest, not 25%. The remaining balance is paid locally on the day. Read the live product page instead of an older OTA price.
