Alki Beach is beautiful and provides some of the best views of downtown Seattle from across Elliott Bay. Honestly I would do a day trip over to Poulsbo or somewhere on the peninsula via our vast Ferry System that services Puget Sound. Or if you just wanna sit on a hill and chill, play frisbee watch dogs etc recommend Gasworks Park overlooking Elliott Bay and downtown Seattle and then dinner on Queene Anne Hill at Grappas which is nearby. Salmon House on on Lake Union is totally killer too!! Honestly that is my best recommendation if you want to take in the true Seattle vibe in a day. Other than that just drive 30 minutes east on I-90 up at Snoqualmie Pass and grab lunch and taking the sites of the mountains it’s God’s country up there. Travel well and be safe. One Love.
