The Acid Castle Rocks are a collection of large boulders on a hillside above Lithia Park. The views are fantastic.
Starting from Ashland Plaza. Take Windburn Way along Lithia Park and quickly turn right on Nutley, then take a quick left onto Alnut Street. Then turn right onto Strawberry Lane and left on Hitt Road. Follow this road to a gate and hike up the trail. Climb uphill for a bit and you will see the boulders on your left.
