Had a terrific morning at Lytton National Park. Best time to visit is the first Sunday of every month to get the greatest value out of your trip here as the society fire the artillery cannons. The park opens at 10am. Suggestively get to the park at 10am which will give you time to see the museum and have a coffee before the tour (which starts at 10:30am). The society members will give you a brief history of the park and fort as well as the artillery used. The tour will then leave to watch the cannons fire at 11am and then the tour continues going through the park until 12:30pm. The tour itself is free but the society asks for a gold coin donation which is definitely worth it. Staff are very pleasant and knowledgeable, parking is available onsite and you will need to set aside about 3 hours to see the attraction.
