This Letterbox cache is NOT accessible from Hwy. 237. It's along a bike/pedestrian trail, next to the Guadalupe River.
The coordinates will take you to a bridge on the trail, overlooking the Guadalupe River. From there, head east to the end of the bridge, and you'll see a sign with three arrows. Two of the three arrows point the way you want to go.
Walk in that direction, until you see another arrow. That arrow points to the general direction of the Letterbox. Keep going until you get to the end of the fence on your left. Make a U-turn to the left, over the rocks, and walk to the bush about 18 ft. from the retaining wall. The decon container is hanging in the bush. It's a bit hard to spot, hopefully it won't get muggled like my last cache here.
Inside the container are a stamp, ink pad and logbook. Take my sig. item, if you want one. Please leave the stamp, ink pad and logbook and close the decon container tightly.
For the FTF, there's a $1 coin and my sig. item.
Parking is available at Yerba Buena Way and Lafayette Street. If you're walking from there, this Letterbox cache will take less than a half hour round trip. From the starting coordinates to the final will take less than 15 minutes walking.
Remember this cache if you're trying to qualify for the Creek-Trail-Walsh Challenge Cache (GC45PDN). I don't recommend placing Trackables here, my previous cache here was muggled, with 3 Trackables inside.
Congratulations to CachetroValley on the FTF!
