Learn about the plant life in the Longview Arboretum by scheduling a tour with a Garden Guide. Tours for groups of 10 or more are available by appointment, at 10:00 AM or 1:00 PM, Wednesday-Friday. Guided tours are $7 per person, which includes your admission fee. Please schedule at least 7 days in advance for group tours and other programs. For groups of more than 10, two docents will be required in order to keep our small ratios and ensure enjoyment and an educational experience for everyone in your group.
