Trail Overview

Short and easy out and back track that leads to an epic open area campsite that would fit 2-3 vehicles. Enjoy stellar views of Mt. Rainier with the benefit of good windbreak trees surrounding the site. There is a well-used stone fire ring if you manage to visit when there is not a burn ban.

Difficulty

Conditions fully depend on the season/weather but expect to encounter deep ruts, mud and mucky water if you are close to rain/snowmelt. Only room for one vehicle, you will get some trail rash from brush/sticks, but an easy drive if you have the right vehicle.

At the end of the trail before reaching the end view point there is a steed drop off with alternating dips, I was able to go down with not much effort other than some swaying side to side, when going up you need to get some speed unless you have lockers and high clearance, I bottomed out, broke my side marker light, ripped off a mudflap and had to retry a couple of times as my front left and back right tire lost contact

Fun splashing after some rain! The ruts might be too deep for a stock Subaru or similar but not sticky mud. No traction problems. Maybe a few fist size rocks.

Slippery/muddy often in places after last nights rain. Some steep incline trails w/ deep ruts often w/ a good lean. Some good burly tree roots often allowing some challenge in the mud. Good fun, but nailbiter a times.
