Camp Fire Camp El Tesoro is a 223-acre multi-use camp located in Granbury, Texas, on the bend of the Brazos River at Fall Creek. Established in 1934, it has been the first choice of North Texas families for almost five generations of campers. El Tesoro has expanded its programs over the years and, in addition to summer camp, currently hosts a variety of year-round opportunities, including family camping weekends, spring break events, group retreats, and outdoor education programs for students from pre-K to high school. Boasting two swimming pools, a new covered equestrian center, and a challenge course complete with a zip line, it is no wonder this camp continues to be a premier location for summer campers and year-round activities.
