The park is situated directly within the historic Arroyo Seco corridor, a vital drainage basin and natural landmark in Los Angeles.
The off-leash dog park is one of the few in the region that provides distinct, fenced sections to separate high-energy dogs from smaller or more timid ones.
The site acts as a connector for the Arroyo Seco Trail system, which stretches toward Pasadena.
The park is managed as part of the City of Los Angeles Department of Recreation and Parks system.
Hermon Park, also known as Arroyo Seco Park, is a community green space located in the Arroyo Seco canyon near the border of Highland Park and Hermon. The park is distinguished by its dedicated off-leash dog park, which features separate areas for small and large breeds. Sports amenities include well-maintained tennis courts and basketball facilities accessible to the public. The site serves as a trail head for portions of the Arroyo Seco bike path and walking trails that follow the natural wash. Large mature trees provide significant shade across the park's picnic areas and open grass zones. It functions as a local recreational hub for residents of Northeast Los Angeles. The park terrain is relatively flat, making it suitable for casual walking and jogging.

Bring water for both yourself and your pets, as facilities can be sparse away from the main parking area.
Use the morning hours to beat the heat, as the canyon location can trap afternoon sun despite the tree cover.
Check the tennis courts early in the day if you prefer to avoid potential weekend leagues or clubs.
Do not leave valuables in your vehicle, as is standard practice for trail-head parking in the Arroyo Seco area.
Leash your dog at all times outside the designated fenced dog park area; clean up pet waste immediately.
