Most elephant 'sanctuaries' here are just tourism businesses but found two genuine rescue operations after extensive research.

Green elephant sanctuary does proper rehabilitation work. Feed elephants, mud baths, making medicinal treatments. No riding obviously. Half day costs 2500-3000 baht but supports real conservation efforts.

Phuket elephant sanctuary similar approach focused on retired logging elephants. Small groups, educational about elephant care and behavior. Both rank consistently high from visitors who understand animal welfare.

Avoid anywhere advertising riding, painting, or performing tricks. Legitimate sanctuaries focus on natural behavior and rehabilitation only.
