Beautiful scerene spot. Fun hiking up and just taking a breather at the top. Minus one star because I tried to swim in it and felt like a giant swamp monster was going to consume my soul.A but murky, super sinking mud, weird tactical plants, goodly warm algae, and some monstrous looking black dragonflies.But besides for the lake trying to consume my being while swimming, a truly beautiful spot.

Love this hike. Great views and exercise.

Lake Ilsanjo is one of my favorite places to hike to. Be sure to bring water. Beautiful Annadel State park with mulitiple trails to the lake. I enjoy swimming in the summer when its hot and dusty.

The trails can get a little beat up, but it’s such a gorgeous park. Enough trails you could go hike or bike all day long and never take the same trail twice.

Beautiful small lake, worth the hike!

One of the most beautiful places in Sonoma County a must-see not too hard to get to I take my granddaughters up there every year

My favorite hike!

Beautiful mists rising from the lake

Awesome hike to fish

Nice spot to sit and enjoy the view in the middle of a ride, love it!

The Lake is always pretty and getting there is a sweet hike.

Wonderful dam. Holds the water in the lake, a table as a conveinent path from one side to the other. What more could you possibly want out of a dam.

Lovely hike

Just a great ride

Always a beautiful place to go to just get away. Lots of trees, plenty of trails to explore and you might even encounter some wildlife like deer, tukey or possibly a coyote.

Absolutely beautiful. It is worth the hike

This is a Beautiful Hike, Fantastic for Picnicking, fishing is pretty good.

Incredible view. Looks like the Sierra Nevada

Great place to jump in and take a dip after a long hard mountain bike Excursion!

Nice

Annadel-Trione State Park is a gem. A nice hike up to Lake is well worth it. Spring Creek trail gives quite of variety of terrain.

Piece and Quite. No better place than the Dam after a good ride.

The second prettiest spot in Sanoma County next to Armstrong.

It was a wonderful swim

Tranquility Now!!!

A great place to relax are hiking to lake or to jump in for a swim.
