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.


Temporary closure announcement

August 8, 2020

Lyon Arboretum will be closed to the public starting August 10, 2020. We will remain closed at least until September 5, per the Mayor and Governor’s decision to close parks and public botanical gardens. Information about reopening to the public will be available on this page closer to that date.

As always, the decision to close is not one that was made lightly, as we know many community members visit the Arboretum as their place of solace. The safety of all our visitors and our Lyon staff and ʻohana are of the utmost important to us. As a community, we must all do our part to slow the spread of the virus.

Rest assured that the Arboretum will open again to the public. We hope our reopening will be in the near future, but ultimately that date will be determined by the COVID-19 situation. This page will continue to be updated as the situation changes.

For COVID-19 updates as they pertain to the University of Hawaiʻi at Mānoa, we direct you to their official page:

Our thoughts go out to those impacted by the virus. We ask that everyone live aloha, as these are trying times. We are all in this together and if we work together, we can make things better! Please take care of yourself and we will be here, waiting for your return.We will be doing our best to continue with our mission to educate the public via posts on our Facebook and Instagram accounts. Thank you for your support and please aloha everyone during these trying times.

Pūpūkāhi i holomua: Unite to move forward
