South Fork is a great base for exploring the San Juans and to our minds, Silver Thread Basecamp is the RV Park of choice. Located well off and below the highway on the banks of the Rio Grande River in a grove of trees, sites are generally well-shaded. Some sites directly on the river are available. The Park is clean and well maintained and the managers are friendly, helpful and welcoming. Due to a problem with our reservation (our fault, not the park’s) we had to change sites for our 6th and final night. We went from a roomy, shady spot we’d been quite happy in, to a riverfront spot that was, well… we decided to forgo our final day of exploring and spent the day fishing and listening to the pleasant river sounds. The best thing we can say about the park? We HATED having to leave.
