WELCOME TO PQCANYON.COM, an innovative Eagle Scout project by Yash Huilgol (Troop 667 San Diego) to explore the jewels of the Los Penasquitos Canyon Preserve (PQ Canyon) on the Web, and to plan a perfect hike.

Yash Huilgol’s project involved refurbishing the existing mile markers and crossing signs in the Los Penasquitos Canyon as well as creating an interactive trail map that can be accessed by all the visitors to the Los Penasquitos Canyon through QR Codes, currently located at the kiosks at each of the trailheads.

With this project, hikers and visitors will be able to find out essential trail information at their fingertips. As always, please be courteous to other visitors on the trail and always respect nature.
