Loch Lomond!
To start, the drive in and out is a rough drive. Very rocky all the way up. You don’t need 4x4 but it will definitely help. What you definitely require is higher then sedan ground clearance. Most SUVs an pick ups made it up fine that I saw, but I wouldn’t recommend your civic at all!
The drive up can be pretty tight in a few spots. I had to stop and hug in to the side to let others drive by. The drive up to the Loch is beautiful.
Tons of room up at the Loch. Though I didn’t see any obvious “spots”. I parked twards one end am made a new friend.
There are a TON of trails. The trail up to Ice Lake is moderate level I’d say. Rocky trail, stream hop, I had to carry my dog over a rough boulder part…
I had intermittent 5G service with Verizon at the Loch itself, and on the trail up to Ice Lake.
