North Sulawesi is tropical and so malaria cannot be discounted. We suggest you follow your doctor’s advice regarding malaria tablets. Officially, North Sulawesi is non-malarial, but if the tablets don’t bother you too much it’s always best to err on the side of caution. We also recommend that you spray anti-mosquito spray onto your arms and legs before going out at night. The grounds at Kungkungan Bay Resort are sprayed at least once per week and all rooms are air-conditioned.
