The Diamond Head Experience provided by Polynesian Hostel is a FREE tour and the only expense is an entrance fee of $1.00 paid at the gate.
If you feel the service you received was above and beyond what was expected, feel free to send a tip/gratuity as you feel appropriate. While certainly not necessary or required, tips are always greatly appreciated.
Tips are accepted at the conclusion of the tours. But you may also send tips online using the paypal.me link listed above.
Thank you so much for your kind support.
