I love this park/set of trails. It does get busy sometimes, so go there knowing that you'll be sharing the trails with potentially a lot of people. Since I like quiet trails that's the only reason I didn't give a 5/5. It's a beautiful location.
Absolutely NOT lightly trafficked. We encountered countless hikers and dogs on our Saturday morning hike (8am start) and some large groups of 20+ people. Very hilly, with multiple steep inclines. Beautiful scenery and a good work out if you're looking for a moderately difficult hike. Nice hike overall but would probably avoid this place on the weekend as it seems to get extremely busy.
