Had not placed a cach in a long time so decided to place one in a favorite geocaching park of ours (Sandy River Delta Park) and what better time than on one of our Birthday's. This is in a very very large off leash dog park, 1500 acres, so if you have any problem with dog’s, it may not be for you. We don't have a dog but have never had any problems with dogs or people in the park, it is so big. There is a $5 parking fee in the park, but the park has bathrooms and picnic areas and is on the Sandy and Columbia Rivers but requires quite a bit of hiking before you reach the waters. The park has very good trails throughout so no bushwacking is needed to find our cach. There are many caches here so it may take several trips if you want to get them all and some of the older ones have grown over to the point of being inaccessible.
