Cobblestone-Orchard Loop with Lake Ilsanjo (~7 miles) (Easy/Moderate)

This hike in Annadel State Park is a gentle pleasant stroll that forms a figure eight with the Cobblestone and Orchard Trails and a loop around Lake Ilsanjo. While this hike lacks impressive views, it is a sweet meander through Annadel State Park. The route travels by old Cobblestone quarries and returns through former orchards with a loop around a small lake in the middle. It gains only 400 to 500 feet so the uphills and downhills are gentle. This is not a "knocks your socks off" type of's more of a great walk to get out and enjoy nature while leaving you time in the remainder of your day to still get a lot of other things done!  There is shade on much of the trail and we are starting early in recognition that this could be a hot day.  This is short enough and early enough that we will NOT be taking a break; bring snacks in your pocket should you need some fuel to get you through.



From Highway 12 and Calistoga Road on the northwest end of Sonoma Valley drive 1.1 miles southeast on Highway 12 (Sonoma Highway) to Los Alamos Road.  Turn right and drive .2 miles to Melita Road.  Turn right and immediately veer left onto Montgomery Drive.  Drive a half mile to Channel Drive.  Turn left and go .6 miles to the posted Cobblestone Trail on the right.  Park in the large dirt pullout on the left.  This dirt pullout is free.


As always:

Give yourself time to find the trail head so that you arrive prior to the scheduled time. That is the time we head out on the trail. It would be disappointing to miss having you on the hike due to late arrival.

Wear comfortable hiking shoes that are well broken in.

Bring plenty of water; we'll be starting early, but it could be a warm day.

Dress in layers. The hike starts off cool but rapidly warms up.

We will be passing an outhouse on our route.

We will not be taking a break; bring snacks in your pocket you can eat on the move if needed.

We should be back to the trail head in[masked] hours.

Dogs are not allowed.

Please always check your email the night before just in case there are any necessary adjustments.

Bring your smile and great attitude!

See you on the trail!

    I love the circuitous route that we took, and the beauty of Annadel was with us throughout. It was a special joy to hike and chat with today's Wanderers. Thanks, Kathy, for another fun and well-led stroll. And, the cold, sweet watermelon and just-picked peaches were sooo good at the end!

    What a great way to start the day! The temperature stayed pleasant, the bikes were scant till close the the end, and the company on the trail was the highlight. Thanks, all for coming.
