We just completed the Lyda 6km segment today. We left a vehicle at the Aguasabon park access point (A11) and then took another vehicle and left it at the south hydro road access point (A9). The views and lookouts were amazing, we travelled along a lot of bays as well. Definitely wear proper footwear, there were some wet areas on the trail and very steeps parts. It took us just over 3 hours at a good pace with shorts stops for snacks and lookouts.

After years of hiking day hikes, multi-day hikes, short hikes, and more in the Northwest of Ontario, I have to say, do this hike! The Casque Isles hike is how hikers should acquaint themselves with the beauty of Northwestern Ontario and especially Lake Superior. Even after three years in a row, I haven't grown tired of doing the entire 53km from Rossport to Terrace Bay. For that hike, I would recommend that a hiker be experienced and in fairly good physical shape but even hikers who are less experienced can enjoy portions of the Casque Isles trail. The beaches on the Lyda Bay section are definitely a must see for any travelers taking Trans-Canada Highway 17. The trail is crosses marsh, hills, boulders, glacial deposits, and beaches, sometimes all in one day. Apart from that, I have yet to see a large animal but have repeatedly noticed tracks for wolves and moose in portions of the trail. Knowing the environmental hazards, and that the trail is volunteer maintained, I would suggest that hikers never travel alone and avoid some sections in adverse weather. Those disclaimers (challenges!) aside, anyone who enjoys hiking in the outdoors and is in Northwestern Ontario, you will not regret doing this trail on a sunny day.
