In September 1943 the Southern California Conference of the Congregational Churches took steps to acquire ten acres of property in the San Bernardino Mountain community of Oak Glen, near Yucaipa. The property had previously been used by a small school for the deaf. The cost was $6,900.

Within the first year cabins were constructed, an old building on the property was enlarged to provide a lodge, a number of other odd buildings on the property were pressed into service, and an administration building was constructed above the parking lot.

In 1944, eight full-week camps were held at Pilgrim Pines.

The Conference purchased an additional 70 acres adjacent to the original property and within about 5 years more land was acquired, completing the camp area to its present size of 160 acres.

In 1952 architect Ralph Bowerman devised a master plan for the camp, a plan that has been largely followed. In 1953 new cabins were constructed and electric heaters were installed. The office building and caretaker’s house were constructed around 1956-1957.

In the first twenty years the Conference invested $75,000 in the land and $350,000 for the buildings. In 1986-87 a major fund raising program, "Pilgrim Pines NOW", was undertaken to update the facilities which were showing the ravages of 35 years of constant use by thousands of people of all ages. What had started out as primarily a summer camp had more usage during the rest of the year by local church groups, public school week-long camps, and many other religious and secular agencies.

Recent celebrations included the construction and dedication of a new fire circle and the "Field of Dreams", both of which were the result of the generous contributions of our Work Campers, the members of the Sun City United Church of Christ, the Tree Huggers, and other Pilgrim Pines supporters. Dining Hall renovations included the addition of two handicapped-accessible bathrooms and a beautiful deck overlooking the Field of Dreams. Full-pressure fire hydrants are newly installed throughout camp adding yet another measure of safety.  In addition, our newly relocated and discreetly shielded refuse area and propane tank sites demonstrate attention to the aesthetics of the natural beauty of Pilgrim Pines.
