Just returned from San Francisco and had great holiday combined with some bird watching.

A wonderful City to easily find a great variety of birds within walking distance or by taking short inexpensive bus rides. Early April is a great time to avoid the crowds and see a huge numbers of sea birds.

We stayed at the Marriot at Fisherman's Wharf which is a nice clean quiet hotel served by all major bus routes.The holiday was booked with Expedia on hotel/flight basis at very reasonable cost of £612 for 7 nights.
