The Gillette Lake trail is an easy hike, the only uphill is at the very beginning just out from the Bonneville parking lot, off of Hwy 14. This is a beautiful hike in the spring when the Trilliums are out in force. This trail actually turns onto the Pacific Crest Trail so it is well marked. You will cross an active gravel road, just before going downhill to the lake, that seems to always have trucks on it. Be aware of poison oak and tons of ticks in the spring. Double check yourself when you arrive back at the car so you don't carry them back home with you.
