I could have come up with something original to write, but this press release just arrived and it sounds like fun for the holidays. Not a lot of hiking involved, but you can add that in yourself on either the island or wherever (Tiburon or San Francisco) you board the ferry.
"Angel Island State Park will host a series of family-oriented Christmas adventures this December. Angel Island’s first Christmas Adventure occurs each December weekend prior to Christmas Day.
"The holiday event includes roundtrip ferry transportation from Tiburon or San Francisco, gingerbread cookie decorating for kids, a visit with Santa and his elf, a ride of the decorated and lit Christmas tram that tours the island, hot chocolate for kids and mulled wine for parents.
"Cost is $36/adult, $22/Kids 6-12 and $7.50/Kids 3-5. Reservations are available online at www.angelisland.com."
I have previous articles on Angel Island hikes, here's one: http://www.examiner.com/article/staycation-hike-angel-island-s-immigration-station
