Lyon Arboretum is part of the University of Hawaiʻi and a public botanical garden. We are nestled in the back of Mānoa Valley, just five miles from the bustle of Waikiki. Lyon Arboretum has over seven miles of hiking trails and boasts more than 6,000 taxa of tropical and sub-tropical plants on our nearly 200 acres.

Information on Admission to Lyon Arboretum

Lyon Arboretum is open to visitors! Due to the ongoing COVID-19 pandemic, we have modified our admissions policies. Access to the grounds and facilities has been limited, as have our hours.

Reservations are required. Your Eventbrite reservation functions as a virtual “ticket.”
Admission is still free, but donations are greatly appreciated. The suggested donation amount is $10 per person.
Due to the ongoing COVID19 pandemic, Lyon is adhering to University of Hawaii, State, and City and County guidelines which include:

  • Masks are required in public areas (e.g the parking lot, Visitor Center/Gift Shop and restrooms).
  • Gatherings of more than 10 (ten) people are NOT allowed.
  • Social distancing (6 feet or more between members of different households) must be practiced.
  • As of September 13, 2021, Proof of vaccination or negative Covid-19 test (FDA EUA approved test) within 48 hours of visit is required.  As part of the University of Hawaii system, we prefer to use LumiSightUH. Proof of vaccination can include a hard copy or photo of vaccination card WITH photo ID, or the Safe Travels Hawaii application showing proof of vaccination. Children under 12 are exempt from this requirement. You can read more about UH’s guidelines here

Visits are self-guided only. Guided tours are not offered at this time. Families can purchase the Arboretum Keiki Kits that will provide an in-depth experience while visiting the Arboretum. Good for both children and young-at-heart adults! Information about the kits can be found below.

For more details and to make your reservation, visit our Eventbrite page.

Due to the frequently changing conditions of the ongoing pandemic, we usually only open reservations a week in advance, often on the Friday before.

Questions regarding reservations can be directed to our Main Office at (808) 988-0456. Mahalo!
