Plan your trip to the Grotto shoreline cave

Visiting winter or early spring? Stop to self-register and pay for your parking permit at the kiosk located at Cyprus Lake Office. Before your visit, read our winter safety and hiking safety pages. 

The Grotto is a scenic cave containing a pool of blue water, located on the Georgian Bay shoreline in Bruce Peninsula National Park, near Tobermory, Ontario. The Grotto is a popular attraction and very busy during the summer and on long weekends. Parking space is limited and quickly fills up. A new reservation system for the 4 hour Grotto parking time slots allows you to plan your trip in advance. Plan ahead to avoid disappointment! 

Campers staying at the Cyprus Lake Campground can hike to the Grotto from their campsite. If you’d like to park in the Grotto parking lot, you will need to book a parking space in the same manner as anyone else.

Check online for Grotto parking availability at Parks Canada Reservation system.  

When to visit

The peak busy season for Bruce Peninsula National Park is summer – July, August and on holiday weekends. At those times, you can expect traffic, long wait times and full parking lots. Reserve your Grotto parking in advance to avoid disappointment. 

Consider visiting in spring or fall when it is not as busy.
