Field Trip/Tour Guide

Typically, most university-level class field trips are self-guided in nature, led by the course instructor.

Lyon staff are limited in their time and resources, however on occasion a staff member may be available to assist the class depending on the request.

Facility Use

There are two restrooms located in the Visitor’s Center.

Classroom space is typically not available unless the tour is led by Lyon Education Staff. Please inquire for details.


Self-Guided Field Trip Cancellation:
Field trips that are guided by the professor can be cancelled at any time without fee.

Lyon Staff-Led Field Trip Cancellation:
Field trips that have been booked which involve participation/guidance of a Lyon Staff member may be cancelled by a school without charge up to two (2) weeks prior to the scheduled field trip date. If a field trip is cancelled with less than two weeks’ notice, a cancellation fee of 20% of the estimated field trip cost will be automatically invoiced to the organizer/school.

In the event that Lyon has to cancel a school’s field trip (due to extreme weather or other reason), there will be no charge to the school.

Group Size

Due to the limited nature of our facilities and for the safety and enjoyment of all visitors, we cannot accommodate more than a maximum of 35 university students at a time.

If the instructor is interested in touring a specific facility (i.e. our Greenhouse or Micropropagation Lab), there may be further group-size restrictions due to the small space.

Larger groups will need to schedule multiple field trips to the Arboretum.

Safety Policies - Environment, Extreme Weather, Physical Requirements, Accessibility

Safety is our number one priority during our field trips. Due to Lyon Arboretum’s lush natural setting and the physically active nature of our field trip activities, all groups must understand and comply with the following precautions and policies:

Lyon Arboretum is situated in the very back of Manoa Valley, in a tropical rainforest ecosystem. Weather is unpredictable and conditions fluctuate between hot and sunny, cool and overcast, and light or heavy rain. Trails can be potentially muddy and slippery, and mosquitoes can be a nuisance. Field trips at Lyon Arboretum are typically conducted in rain or shine, and instructor must be prepared to adjust activities on the spot due to sudden changes in weather.

In the event of extreme rain, high winds or other dangerous weather conditions, field trips will be cancelled for safety reasons by Education Staff no later than 7:30am the morning of the excursion. If we cancel your school’s field trip we will try our best to reschedule your group, depending on the availability of open dates. There is no charge to you if your field trip is cancelled due to extreme weather. Occasionally weather becomes extreme as groups are in-transit to or already at the Arboretum. In that case, instructors must be prepared to adjust activities as best as possible to ensure everyone’s safety.

All attending instructors and students must be prepared for the active and outdoor nature of field trip activities at Lyon Arboretum*. Participants must be able to stand and walk around for the duration of the visit, as well as navigate uphill/downhill slopes and uneven or unstable terrain. Participants may be subject to mud, heavy rain, sun, wind, and mosquitoes and must dress appropriately to ensure their safety and comfort.

*Please notify Lyon Education Staff well in advance of your school’s field trip date if there are any concerns regarding accessibility or requests for special accommodations.
