I agree with Traveler11223. Port Angeles (not Port Angelas) is not a particularly interesting place. Also, if you have to be in Port Townsend for the 5:15 ferry, you want to arrive at 4:15, which means leaving Port Angeles about 3:00 pm.
PT is a very pretty town, with quite a few things to do, some of which Traveler suggested. Another thing you could do would be to visit a few lavender farms in Sequim, which is 25 minutes east of Port Angeles on route to PT. You could also spend a little time at the Dungeness Spit, also in Sequim. It would be a nice contrast with Hurricane Ridge.
