An easy, relaxing local adventure.
Meet at Velo Rouge in the morning. Bike to Larkspur, partly along dedicated paved bike trails (about 17 miles). Rent kayaks from Outback Adventure ($30 for 2 hours, I called ahead since we were a group). Paddle along Corte Madera Creek and side creeks under Mt Tam (a few hours before low tide so we were paddling against the current on the way in but the ebb was carrying us back out). Head to the Marin County Brewing Company a few blocks away for some food and refreshment. Catch the 4:45pm (sunset) ferry (also right there) back to SF.
A friendly group of 6, a casual pace, we saw wild turkeys (right in front of the “TURKEY XING” sign, no less), egrets, herons, cormorants, pelicans, sandpipers, ducks, a vulture, and a harbor seal.
