Hiking to see the Georgian Bay shoreline and the Grotto sea cave is a highlight for many visitors to the area. Here are some tips to be prepared to get the most of your visit to Bruce Peninsula National Park.

A hike to the Grotto and Georgian Bay shoreline begins at the P1 parking lot located in the Cyprus Lake area. The Georgian Bay Trail is the most direct route to the shoreline and is approximately 30 minutes. The beginning of the trail is rated Easy with a wide crushed gravel surface and few hills, however the shoreline of Georgian Bay is very rocky and can be challenging for children, elderly and those with mobility issues. It is necessary to pay attention to your footing and to keep children well supervised. The portion of the Bruce Trail leading to the Grotto does require some climbing over slippery rocks and tree roots. 

You can choose to return using the Georgian Bay Trail or an alternate route using Marr Lake Trail or Horse Lake Trail. The entry points to these two trails are located a short distance, in either direction along the Bruce Trail, from the Grotto. Using these trails to return will allow you to experience a more natural and challenging hiking experience and you should allow up to an hour, depending on your pace, to return to your vehicle. Reservable time slot parking is in effect at P1. Be sure to check distances, times and trail names using the Visitor Guide while enjoying your hike.

    • Once you arrive at the shoreline, keep left and follow the white blazes of the Bruce Trail leading towards the Grotto.
    • The Grotto is a large sea cave containing a pool of water. An underwater tunnel extends from the pool inside the cave through the cliff to Georgian Bay. This often makes it appear as though the pool is glowing on sunny days.  
    • There are two options to descend into the Grotto:
      • The chimney is a small rocky tunnel that allows you to cork screw your way down to the Grotto opening. Those with mobility issues and children should use extreme caution. Take your time and maintain 3 points of contact while descending.  Be aware of others coming up.
      • The other option is to climb down the 12 meter (40 ft) open cliff face. Know your limits. Once again, those with mobility issues and children should use extreme caution and know their limits. The cliff face includes a series of shelves and rocks that you can climb down. Typically, this route results in wet feet.
      • Either option is suitable for exiting and climbing back out.
