The front of their flyer says, "Want to really help? Don't send more people to the beach. And leave the turtles alone."
Alternatively, you could make your way towards the south of Juara and put in some physical effort here in a bid to improve the health of sea turtles' population and conserve their breeding grounds.
Volunteers can stay at the sanctuary for 120RM a night, including breakfast and lunch, and partake in housekeeping and conservation activities. You'll have to do the mundane things like cutting the grass and cleaning the rooms, but you'll also participate in night time beach patrols and releasing of the baby turtles when they hatch, which would undoubtedly make for an enriching experience.
Sea turtles are at risk of extinction within 50 years and every small part counts. Even if you don't have time, a donation will help to keep this place going. Alternatively, choose to stay at Barook River View or the Juara Lagoon, just a short walk further south, where parts of the proceeds goes to funding the project.
