Here are some examples. The salmon fishing shore excursion on the ship in Ketchikan was $179. Guys that went on it basically trolled for salmon and picked up a couple of small fish.
One of the guys in our group rented a rod and reel for $2 hr and purchased a one-day fishing license for $10. He fished from the Ketchikan Creek bridge. He caught and released 9 beautiful salmon in about 40 minutes. He returned the rod and reel for a total cost of $2. He had a great time.
The city bus in Juneau stops short of the Mendenhall Glacier park by about 1/2 mile. Total cost to get to the glacier is $.50 each way. You can also take one of the Mendenhall Express transfers for $5 each way, if you don't want to walk the 1/2 mile.
