Brookside Golf Course, Golf course in Pasadena, California

Brookside Golf Course is a 36-hole complex in Pasadena featuring two distinct courses, the C.W. Koiner Course and E.O. Nay Course, separated by the Arroyo Seco waterway. Each course offers its own routing and character within the larger property.

Both courses were laid out by architect William P. Bell, who gave the complex its two 18-hole routings divided by the Arroyo Seco. The C.W. Koiner Course plays to par 72 at over 7,200 yards, while the shorter E.O. Nay Course is a par 70 of just over 6,000 yards. In late January 1968 the Koiner Course hosted the Los Angeles Open on the PGA Tour, won by Billy Casper.

The courses form part of the broader Arroyo Seco Natural Park and serve the community as a recreation hub for both sport and leisure. Local players return regularly to enjoy the mix of manicured greens and natural surroundings.

The two courses are split by the concrete-channeled Arroyo Seco, with the C.W. Koiner Course running along the western and southern ends and the E.O. Nay Course along the northern end. Practice facilities sit at the clubhouse: two putting greens, a chipping area, a practice bunker and a driving range. During UCLA home games and the New Year's Day Rose Bowl Game the grounds become event parking, so tee times are affected.

During major events at the nearby Rose Bowl stadium, sections of the golf courses are temporarily converted into parking areas that accommodate thousands of vehicles. This flexible use shows how the facility serves multiple community needs beyond just golf.
