Review: Started at 10 Mile House Rd. to Guardian down to South Rim Trail and back. Guardian is a great trail but I doubt it's possible to ascend this trail without hiking. South Rim is a mess of rock (think ascending a creek bottom). I seriously doubt anyone would ride this trail but for the view. Both of these trails are constant climb or descent their is no rolling track period. Great views bad track = good hiking trails (or good downhill).

Review: Kinda funny so many people can not ride North Rim, will not even try, uh uh try a single speed,,,,,,ouch

Review: Wow - I was in the Chico area over the weekend for a sporting event and decided to bring my bike. I just headed out on the North Rim Trail and tried to find my way. Lots of nasty lava rock, very little soil or crushed rock on the climb and up top. The trail that I took back down (B Trail I Think) was pretty technical with some very steep drops on a narrow trail, but had more soil and rideable terrain. Vegitation was very overgrown and it was like riding through a tunnel in places. I was amazed I didn't end up with any ticks or poison oak! Take the other posts advice and get a map if your are not familiar with the trail(s). I know that I will next time! It probably could have made a better overall ride experience!

Review: east along fence line, double track it will wander to and fro till just before Manzanita Ave, right across bridge. head east across Ave, to Five mile Park cross at bridge, left on road, single track will head west then loop back east.
cross road, take first single track to fist parking area. Head up North rim trail, just over four miles.

retrace you self or the number of options back through park

Review: Starting near the entrance to Upper Bidwell Park, enter Middle Trail near the
gate and proceed to the "Cross". Turn uphill and follow 'North Rim" for
approximately 2.5 miles to 'B' Trail. Decend 'B' Trail to the fire road and turn
left. Follow to the creek and cross to 10-Mile. Ascend 10 Miles to the top of
the south rim canyon wall. Decent South Rim and exit.

Review: the truth about bidwell park...... first of all there are many rides in this park. there is the north side, aka "north rim" and the south side, aka "south rim". then there are the many connective trails. on the north side you start by going up from the "cross." a very rocky double track road. at mile one to the right is the trail head for "maidu". a short groomed switch back hiking trail down to "middle trail" very fun roller coaster ride not too technical but you do need some skills. or stay straight and continue up approx. 1100 ft. climb in 4 miles to "b-trail", a technical switch back trail which descends 1.5 miles and connects with "middle trail" first to the right, and the park road next. if you choose "middle trail"......good choice! a super fun descent all the way back to the shooting range, but very rocky with baby heads, poison oak and snakes. about half way down you can drop down to "lower trail" if you wish. also fun rocky single track, or continue on "middle trail" back to the cross. all of these trails are marked and you can and should pick up a map at any local bike shop.......if you are a strong experienced rider go left at the road after "b-trail" to the end where it becomes a short single track section, and dead ends at the creek. cross the creek and ride the steep road up to "guardians trail." this a very hard technical trail recomended for experienced riders and you should not ride it alone. the first 1/4 mile is very easy then it will start to become very technical. after about 3 to 4 miles it drops down to "south rim," also known as "annie bidwells trail" here is where it gets confusing......there are lots of alternative bootleg routes. most of them will take you painlessly back to the shooting range, but you may get lucky and end up somewhere else! when you finally arrive at the five mile go right, cross the bridge/creek, stay right on the road and the "cross" is just ahead where it all began.

Review: The North Rim side is more technical, with four basic options; lower (easy), middle (moderate), upper (difficult) and north rim (advanced) trails. If you ride the north rim trail to the end, you can shoot down the B trail. Stunning views. The South Rim side (if you shuttle up to Ten Mile House Road aka Greengate as there is a green gate at the trail head) starts with a STEEP fire road and you tie in to guardian trail. There are extrememly difficult (for me) sections with names like "Bloody Pin". Just be prepared to fall off your bike. If you manage to escape without flying off you probably weren't trying very hard. An absolute blast.

Review: I always get hurt riding here and always come back for more

Review: Follow single track out to five mile cross bridge, head up into lower park. first gravel lot leads to North rim,follow it to Blue Oak, drop to Miudo, head east, right on Middle trail, which rocks and rolls along till B trail go right dropping to road.

Gravel road is pretty beat not a lot of rest time, it will dead end, with a single track leading to the river at the very end. Float you pinkies in the river, nice place to tell some stories for a bit in the shade.

Cross river follow single track to fire road climb and take first right up another fire trail, very rustic as you head for next single track to your right heading west, do not let you mind wander there are places to fall through a bush to the rocks and river below, a lot of bootleg it seems so keep heading west, till golf course. We head into town here but you should cross into path which crosses golf course back to Upper park entrance

NOT AN EASY RIDE, DO NOT THINK YOUR AN ADVANCED RIDER!!! BE ONE

Review: off of north rim trail there is bloody pin trail. BLOODY PIN TRAIL IS ROUGH! the name is a pretty accurate description. lava rock the whole way, rough as hell, super tight twisty singletrack and the occasional cliff to watch out for. this is the toughest trail i have ever ridden. i ended up not being able to brake enough for a right turn and had to ditch the bike but still ended up falling off a 5 ft cliff drop. i was totally fine but coulda gone very bad and if i was by myself i wouldnt be here today. i love it haha also humboldt trail here looks pretty sweet. we hike up from north rim trail almost back to the road (hwy 32) and there was some gnarly stuff there

Review: bidwell is badass. i rode here a few times while visiting freinds. i forget how to get to the place we rode at, but i think it is called green gate. it follows the ridge next to the canyon pretty much the whole way down. VERY TECHNICAL SPOTS a few rock gardens, but very tight singletrack and a few kickers here and there

Review: You hit it right on the money - great trails and very linear park. Three main lower trails on North side wtih double track N. Rim trail on upper ledge. Two main trails - now a third option with newly constructed Volunteer trail on South side. Much more technical and a good climb unless you shuttle up on Hwy 32. Nice "epic" is to circumvent the park by going out North side - cross Butte Creek at end of Park Road - climb up South side and bike back out. Overall approximately 20 miles and every type of fun - couple of roller sections, hard lava cap, some roots, couple of good climbs, good downhill and lots of technical.

Review: Start at the gate at the parking lot and stay to the right. The trail will have a slight incline as you move along the right side of a small point. Approximately a mile into the ride the trail will fork. Stay to the right and go toward Horseshoe Lake and follow the trail as it flows up and away and then back down to just above the parking lot of the lake. There will be a trail marker and fork at the start of Maidu trail and you immediately start the .35 mile climb up to North Rim trail. There are 3 major switchbacks and numerous waterbars and steps to navigate. At the top you can proceed back to the start point on the double track of North Rim. It is fairly easy to navigate but unforgiving lava cap. A perfect after work quick loop with a good climb, sweeping singletrack and fast rocky doubletrack back. Option to North Rim doubletrack is to head straight over to the fenceline and ride the Fenceline Trail singletrack back to the start point.
