Hard incline for 2 mi, mostly asphalt road. Highly trafficked, impossible to take dogs off leash.

RunningGreat!

Perfect trail for running and cardio. All up hill running with a great view of the city. Bathrooms at the bottom by the lake and bathrooms at the top. Easy and convenient to get to.

Great trail. Super glad I had pro version to know where we were. Even with it we missed a turn but it was ok. Starting out straight up on clean path. You go to double peak and the down part is very steep with lots of rocks... just be aware and take your time!

All up hill for the first two miles and then you turn around and head down. Very steep incline. Views are very pretty but it was also crowded. Worth doing once, but not sure I’d do it again.

This is 2 miles ALL UPHILL. if you don’t like hills or can’t do it this isn’t the hike for you. You can also drive to the top for the view (which honestly is just ok). Lots of people and dog friendly. Mostly masked people but of course not all.

HikingGreat!

Parking -- There's a small amount of parking adjacent to the trailhead, as well as street parking in the nearby residential community, which is where we parked. Restrooms -- Yes! There are two unisex surprisingly well kept restrooms at the trailhead/small park. This makes it a five-star hike in my book! Hike -- We walked around Discovery Lake, which was quite busy with walkers, runners, kids, families. We saw some ducks in the lake, which is about the only wildlife we saw. From the lake, we continued on the Double Peak trail. It includes a few inclines and at the top offers great views of San Marcos. It's very new with nicely groomed, wide well-kept trails and benches for resting. Decent signage. It runs through some very large newer housing areas. Dog poop bags and trash cans available by the lake. A lot of people wearing masks, but I would have like to have seen more.

Nice trail. Did not realize it was so close to homes but still good and great views at the top. Quite a few people on the trail and most were not wearing masks-ugh.
