Caines Head Trail is a 13 mile out and back trail located near Seward, AK and is rated as moderate. The trail is primarily used for hiking and is accessible from May until October.
Great hike with lots of opportunity to enjoy gorgeous views along the way. I did this hike with my little dog back in July when the salmon were spawning and saw quite a few making their way upstream. Blueberries were just getting ripe and the trail had enough ups and downs to make it interesting yet not TOO challenging (although the first part, which is also the last part on the return trip, is a long slow decline/incline and not very "exciting" but don't give up!). Even if it's high tide hiking to Tonsina point and turning around is still worth it.
There are a few ways to do this trail. Because part of it is coastal and is submerged during high tide, you can either hike, spend the night in a tent, and then return next low tide, or you can kayak from Lowell Point to Caine's Head and pick up the trail there. The end of the trail is at the remains of a WWII fun battery, Fort McGilvray.
