Annadel State Park, located 60 miles north of San Francisco on the eastern edge of Santa Rosa, offers miles of trails for hiking, mountain biking, and trail riding. For wildflower lovers, Annadel Park offers a great variety of flowers from early Spring until early Summer, especially on a hike around Lake Ilsanjo. The best months to see the park's wildflowers are April and May, but there are some plants in bloom as early as January and as late as September. Dogs are not allowed on trails. Dogs are allowed on a leash under your control only on Channel Drive (a paved road) within the park. Lake Ilsanjo offers excellent fishing for black bass and bluegill. Black bass weighing nine pounds and more have been caught here. A purple plastic worm is a favored bait for the bass, while the bluegill favor garden worms, small crayfish, and grubs. If you are 16 years of age or older, you must have a California fishing license. Ledson Marsh dries up by late August or early September and so no fish are found there.

Nice hike with lots of beautiful scenery and a good amount of wild life  its a good hike if you want to get a good hike in for the whole day and feel it the next day. I enjoy going once a week!

Beautiful. Moderate climb, the marsh at the end is gorgeous. Combination of burnt, new, and existing plant life. Rocky paths, not many people out there, occasional mountain bikers.

good first 3.5 miles with a walk on asphalt for the last mile.

A pleasant, moderate hike to Lake Ilsanjo and back. Went on a very sunny Saturday afternoon in early July. Nice heat under the sun but not sweltering.

nice rock garden for mountain biking

Beautiful first 2 or 3 miles with nice views. Ended up walking the last mile or so on the road in the sun though.

pretty fun and easy hike.

Beautiful hike with lots of variety. About half was shaded, the other half exposed. Lots of wildlife including flogs and deer.

This trail is just down the street from my house. At this writing the trail is open an cleared but there is a great deal of evidence of the October wildfires. The park suffered a great deal of burn but is open and clear.
The level is probably difficult with large rocks and roots in some places. Lots of hikers, mountain bikes and runners but it’s never too crowded.

Beautiful trail, especially a few days after the rain with a strong stream in the creek. Other than a short stretch that was too steep for me to run up or down, moderate trail. Free parking on the street near trail head.

I noticed lots of 4+ star ratings on this trail but 3 stars on sugarloaf vista, just a few miles away. They aren’t really even comparable from a views and terrain diversity perspective. maybe it’s the mountain biker preference for this trail.

It is a beautiful hike, but many bikes on the main trail. we got lost for a little bit because the rain has washed away some mud, and plants are thick. overall, it is a fun hike

This trail should be rated moderate, at best. There are not a lot of steep climbs. It is a bit long if you’re not used to hiking 6 miles.

Great quick family hike! Took about 2 hours round trip with 3 Kids(13,12,10). Hit most of the goals on my Fitbit in 2 hours. Not bad!

Very easy trail with some great views along the way.

My go to route for an efficient, fun 5 miler. Always fun bombing down rough-go and getting in some good flat around the lake. Add 2 extra miles by taking a right at Orchard and coming back on Cobblestone to meet up with Rough-Go.

There’s a nice series of trails, some challenging. It’s picturesque though also crowded with many people on the trails which are narrow and often shared by mountain bikes whizzing by which definitely disrupts what could be a calm scenic vibe.

Wonderful easy trail!

Went to trailhead but it’s all private property, no trespassing

Nice variety of not too steep and level. During winter small brook to cross.

This review is outdated since I did this hike before the fire- not sure its condition now. Beautiful, particularly at dusk.

Very nice lightly moderate trail. Not many birds, but lots of bikes on this Saturday, but all well trained in trail etiquette. Very relaxing.

I prefer this route in reverse. One of the best routes (trail running) at Annadel SP. Marsh is challenging but very run-able and flying down South Burma is a real treat, with very different plant life at a higher elevation. The trail in the South Burma section is some of the most pristine single track in the park. Start at John Beckmeyer Trail on Parktrail Dr. for easy access.

Always a good time coming down Spring Creek - look out for turkeys! Access the trail from Stonehedge Dr. as well, instead of Spring Lake.

Either direction you run this route, you are going to have a great time. Rough-Go is steeper going up than Canyon and more technical/single track trail. I would recommend coming down Spring Creek Trail as an alternative - that trail is very shaded and not as rocky as Rough-Go if you are looking for a smoother descent. Parking on the road at Parkridge Dr. is easy and plentiful, definitely the best way to access Annadel from the Santa Rosa side. The other access point is to park at Stonehedge Dr. just north of Parktrail Dr. Enjoy!

Really gorgeous trail. Pretty secluded from other people.

Don't go if it's toasty out. There's very limited shade spots so it's direct sun. Make sure to wear sun screen!! Otherwise gorgeous trail absolutely loved it
