A good place to check out the current conditions on Bear Mountain is through the Website Trailforks.com that has a Dynamic Trail Map of the all the trails in the area, with updates provided by the mountain bikers that use the trails.
Parking is best at Saunders Street just off Richards Ave.
Bigguns is a black diamond mountain bike trail with some steep sections and possible blind spots behind some jumps – USE CAUTION hiking up or down to avoid a collision with a mountain biker (they have the right of way)– be aware at all times.
I discovered this trail going for the nearby Tower Cache and loved the hike, terrain and the view at the top. I hope you enjoy the trail and the workout as much as I did and will continue to do. Wear good footwear as the trail will be very slick on wet days! Depending on weather conditions the round trip from the parking lot on a good day is probably around 1 – 1 ½ hours.
