On the way back from 3 Sisters Falls, we decided to add on a roadside, quickie hike in Flinn Springs County Park. The hike begins at the back of the park.
This small 40-acre park near Lakeside has 1 short trail that takes you up a consistent, steep incline to a great vista above Escondido and Lake Jennings.
Once you reach the saddle you can go east to reach a short peak or west to climb Silverdome Peak or south for Flynn’s Peak. I’m not sure which one we scrambled up, but it was definitely a scramble.
It’s rated as moderate, but if you are less than moderately fit, it’s likely you will suffer. (Especially if it’s a hot day as the trail is completely exposed.) That being said, it’s a good, short workout and “bun burner”.

I wouldn’t go out of my way for this one, but if you’re driving by and want a leg stretcher / burner—go for it.
There’s picnic tables and a lovely wood pavilion too.
