The Yelm Prarie Line Trail is part of the rails to trails program in the Yelm area. The bridges on the trail are quite stout as they used to hold up trains. There may be heavy foot and bike traffic on days with nice weather so stealth may be needed.
The trail leading up to the cache is paved and level but you will need to go off trail to get to the cache.
Please re-hide well and use stealth. I had a cache here before and it got muggled 4 times.
