Actually it is not berg lake but Grewingk Glacier that fills the lake of the same name. This is located across the bay from Homer AK in Kachemak Bay State Park. To get here you hire a water taxi and they drop you off on the rocky beach about 3/4 mile from the trail head in our case because of the tide. The trail is 3 miles to the lake but pretty flat. Deep green forsest gives way to light alder trees as you get close to the lake. There were many small bergs floating on the lake. We then took a different trail back to another spot where we would be picked up. It too was about three miles long but decidedly not flat. Then when we descended to the water we were faced with about 1/4 mile of very narrow rocky beach to get to the boat. A nice day and pleasant hike.
