Today, for no great reason, I decided to see if it's possible to walk the full perimeter of Treasure Island. I parked at the Treasure Island Museum and headed north up the Avenue of the Palms. I've been here many times and it offers stunning views of San Francisco and both the Bay Bridge and the Golden Gate Bridge. The path continues around the north of the island and then you need to work around a blocked off area to get back to the coast. The east side is less appealing with a lot of garbage along the path and a view of many barges and the Port of Oakland peeking out under the new section of the Bay Bridge. Finally I was fully thwarted as the entire south west corner of the island is a mess of construction (and a rather unpleasant portable toilet staging area). I had to head inland all the way to 9th Street before cutting back over to the Avenue of the Palms. Overall I'm glad I tried but I can't recommend it.
