All of the ones that have been mentioned are excellent. Preferences depend a bit on what you are after (e.g., being with others vs. being relatively alone; places to hike; places to swim--the H20 temperature does vary from bay to bay and there are a few anchorages that have sand beaches). Here are a few others that we have enjoyed (east to west): Beaverstone Bay and Mill Lake have lots of anchoring choices; Thomas Bay (a little tricky to get in to, but with the high waters the last two years, no problem--east of Killarney near the entrance to Collins Inlet); Browning Cove at Heywood Island (we prefer going east from Browning Cove down a channel to an open anchorage because Browning Cove attracts lots of boats because it is close to Little Current); Sturgeon Cove--very tricky to get into, it helps to follow someone in, but very nice anchorage, a kinda' beach, and there's usually some wildlife on shore in the evening (e.g., porcupine, deer, bear); Louisa has nice views of the La Cloche Mountains,is relatively good during a west wind, and has a beach, but it can have a surge that rounds the southern point and it attracts lots of day trippers from Little Current and other overnight boats; Matheson Island--good views of the La Cloche Mountains; north of Hotham Island--many anchorages in this area, enter at the west end; Fox Island, southern cove-- we prefer this anchorage to the Benjamins, can explore around the island and motor or paddle to the Benjamins; Croker Island--near the Benjamins and usually doesn't have the crowds of the Benjamins, the southern most bay is to be preferred; Shoepack--near Little Detroit and Spanish, a deep anchorage that is well protected in most winds, anchor and tie to shore. These are anchorages that are our most common destinations in addition to all of the others mentioned. Of course, we all have a few favorites that we don't disclose. That depends a bit on the boat. When we had a swing keel sailboat, we were in places where no one else could or would go. Be moved up and our current sailboat has a deep draft and we're more limited. We also have a couple of destinations where we know we can "rock dock"--pull up to a vertical rock face and tie to shore. Definitely get the Ports Cruising Guide. It has excellent photos of marinas, anchorages, and important information (e.g., telephone numbers of marinas, services, tips for cruising). It covers both the North Channel and Georgian Bay. You can purchase a copy at Turners in Little Current or order it ahead of time. send me a PM if I can provide additional information.
