Tips for visiting the botanical gardens of Oahu

Bring bug repellent – many of the lush gardens are filled with mosquitos that are vicious so plan on bringing spray and protecting yourself while exploring these gardens

Locate the garden on your google app or GPS to locate each garden and parking lot more efficiently

Grab a map of the garden – check out the information center and grab a map layout so you don’t get lost and go around in circles

Support the botanical garden – many of these gardens offer gift shops, café foods or hand made snacks or desserts and operate on shoe string budgets – it would be fantastic to keep them operating for everyone to enjoy and supporting them with a purchase would be easy enough

Even on cloudy days, the sun rays in exposed areas of each garden can create sun burns so cover up or use sunscreen when visiting any of these beautiful gardens.
