Freshwater shipwrecks, limestone cliffs and clear, cold Georgian Bay.
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
The park preserves more than 20 historic freshwater wrecks and limestone dive features. In the approved visitor area, The Tugs in Little Tub Harbour, Sweepstakes and City of Grand Rapids in controlled-access Big Tub Harbour, W. L. Wetmore, Arabia and Forest City offer very different skill demands. Dive Life Tobermory markets day charters, guided shore dives, training and gear services from Little Tub Harbour. This is cold-water diving in every month, not tropical beginner diving. Scuba participants must register, obtain the park dive pass and use the designated access areas. The park forbids penetration of Sweepstakes. See park dive guide and safety rules.

Operator Checklist
Book a realistic site tier, not simply a boat seat. Ask the charter for exact minimum certification, cold-water recency, current schedule, rental/fill provisions and weather cancellation rules. Dive Life advertises May through October charters; published tours are not proof of availability on any particular day. Register for scuba in person at an authorized park location before diving, pay the pass, obtain current harbour zone information and display a dive flag within 30 m of diving activity. The park states Big Tub wreck access follows scheduled controls from the May Victoria Day weekend through the October Thanksgiving weekend. Do not enter vessel channels or unauthorized harbor water. As of October 28, 2026, the shared visitor centre was temporarily closed October 26 to 30, and the shop published seasonal hours ending in mid-October, so confirm a valid registration route directly with Parks Canada. No vessel penetration or overhead route is implied by a wreck/cave listing.
