For an adventurous alternative to the ferry, try kayaking across the bay. The views from Angel Island are that much sweeter when you've powered there on your own. Sea Trek will suit you up and guide you from the Sausalito waterfront, picking the best route based on the current tides and winds. Unlike casual waterfront kayaking, the Angel Island Crossing trip is challenging; it's a 3-mile journey that takes kayakers across the second deepest part of the bay, Raccoon Strait. Kayakers arrive at a beautiful beach on the island's isolated west corner. From there, take in a trifecta of iconic scenery: Tiburon, the Golden Gate Bridge, and Mount Tam. Spend some time exploring the island's Civil War structures, some of the oldest on the West Coast. Sign up soon: There are just two more Angel Island Crossing trips this year—October 26 (this weekend!) and November 30. Go forth and kayak!

TIP: Join the Bay to Breakers of sea kayaking this weekend: Paddle around Angel Island with 200 other kayakers on Saturday, October 25 to benefit people with disabilities and inner-city youth at the annual Paddle-a-Thon.
