There are shelters placed in key locations around Harrison Hills Park that are available for rent from $30 and up. Park shelters are well utilized by visitors, the most popular being the Overlook Shelter (wheelchair accessible) located near the scenic Watts Overlook with a huge playground encircled by a 1/3 mile paved loop trail. Shelters come equipped with picnic tables that can accommodate 30 people, port-a-johns or restrooms, and some have electric and water too. The largest shelter - Yakaon Pavilion (pic above) opposite the Environmental Learning Center - seats 60 people and is set up for larger events such as the recent Harrison Hills Halloween 5k/10k Trail Run that attracted over 300 participants.
The map below shows where the shelters are located within the Park. Please visit the Allegheny County website for Park Rentals.
