My 2 older sons (age 19 & 22) and I fly from SEA to Anchorage today for 2 days of fishing on the Kenai Penninsula. Monday we drive from Soldotna for our Anchorage flight at 7:30 PM, so we have that day to side trip/sightsee. For sure we want to go to Portage Lake to do the boat tour. What else could we do that day which is no or low cost before catching our flight? I'm considering Seward to see Exit Glacier but am not sure I want to do the 2 hour side trip off the route. I've never seen Anchorage itself on my 2 previous trips (but this is a first time AK visit for my sons). Our interests would include scenery (glaciers), wildlife, etc.
Any suggestions are welcome. Thanks.
