Rosaryville St​ate Park - Park Quest

Rosaryville Entrance Sign​​

​​"Invader Investigation"

Getting started: This Quest begins at the Agriculture Heritage Trail across the field from the Rosaryville Pavilion. You will notice a Park Quest kiosk placed near the entrance of the pavilion parking lot, which includes the information you will need to complete this quest. To begin this quest, follow the tobacco sticks (thin, three-feet high wooden stakes) across the field to find the beginning of the trail.

When you meet up with the Agriculture Heritage Trail, turn left and look for the first station. The Quest has markers along it to assure that you are on the right track. There are six stations to stop at along the trail. Each one is a specific invasive plant that needs to be identified using the Invasive Plant Dichotomous Key and the Invasive Plant Guide, which is found online. Once you have keyed out all six plants, you will be able to solve the puzzle.

The Quest trail is 0.7 miles from the kiosk to station six. When you reach station six and solve your puzzle, turn around and go back the way you came to return to the parking lot. In total, this Quest is 1.4 miles.

Please note that parking may be limited at the pavilion lot during summer weekends when the pavilions are rented.
