Come now for the best flower show! With lupines, sunflowers and more, plus roaming cows, the pastoral scene here will take you away from the bustle of nearby parks. There's a big loop trail up the hill, and numerous bike paths to follow. I had a lot of fun here!

Located at the intersection of HWY 93 and Marshall road in south Boulder, Marshall Mesa is a great…read moreplace to go hiking or mountain biking if you like steep and rough terrain. Trail maintenance is very little if not at all so get ready for some extremely rocky, muddy, and partially washed out trails. The good thing about Marshall Mesa is its expansive trail network, one can connect up to the Marshall Valley Trail, Coal Seam Trail, Cowdrey Draw Trail, Greenbelt Plateau Trail, and Community Ditch Trail. All trails are hiker and mountain biker friendly but most of them are very narrow and only allow a single direction of traffic at one time. Good hiking footwear or a strong, well built professional grade mountain bike is required as well as sunscreen and a couple of bottles of water since most of these trails are fairly long (10+ miles long one way). There is a large free parking lot across the street from the entrance or a pay for parking lot on the park property itself. So go out and enjoy the sights and sounds of the great Colorado outdoors.

This trailhead is a hub with access to many other trails. I wanted to climb Flagstaff Mountain and…read morethere are multiple options to get to the top. I started with the GC trail and created a loop with Rangeview and Flagstaff. Rangeview delivered an amazing view of the Rockies. GC is on an incline so you get to look down into the creek and canyon. The western side also offers views of the adjacent Chautauqua Park. Flagstaff summit was not as dramatic, and upon the descent you look out onto Downtown Boulder. I inadvertently took Crown Rock trail, which I do not recommend. It has a lot of loose rocks and gets slippery. Trails were easy to follow and major intersections had clear signage. Only six parking spots! However, you can park for free with some off-road spots on Baseline Rd. I regret starting at 9:30 as trails were pretty sunny. Rangeview offered some needed shade.

Wow what a marvelous trailhead! The other reviewer was right, you could get to all of Boulder…read moreMountain Parks from here. I arrived around 11am on a weekday and the lot was about half full. There's a few trails that all connect up to Green Mountain, so take your pick. It too me about an hour to summit. The trail was beautiful and in better shape than the Bear Peak trail. It's less steep, but still pretty long and can be an adventure. You get some amazing views, better than Bear I think. Seeing the first flatiron above the fog was so pretty. The summit sports a register and a lot of chickadees begging for food. Don't feed them! Enjoy the mountain air and sunshine, and the fact your so close to town after your hike!

It's far enough away to have the serene 'mountain' feel but close enough to be convenient. You can bring your dogs and walk them on-leash (they'll love this trail!). The trail seems to be popular for trail running and biking, but you cannot bike here on Wednesday/Saturday. So those days are the best for hikers. There are also picnic areas available for picnicking as well! Plenty of shade for cooling down, too. The only downside is parking. There are two VERY SMALL lots with one overflow lot. On the weekend it gets busy and finding a spot can be a real struggle.

There's parking for a dozen or so cars, some signage about the surrounding nature, and a small picnic shelter. Very popular spot with runners, walkers, and bikers. Conveniently located but the traffic can be a bit fast going by. Excellent spot for sunsets and western views into from Pikes Peak very far south, Boulder and the Indian Peaks to the west, and north to Longs Peak and Wyoming. Lots of wildlife including bald eagles, prairie dogs, and coyotes.

The bathrooms were not operational during our visit (early July 2024) which was pretty inconvenient when you want to eat/drink by the water. The parking lot will fill up but there is some additional parking across the road. This spot could benefit from 1-2 more picnic tables.

Describing this trail is like Buddy the Elf describing his journey from the North Pole, "I passed…read morethrough the seven levels of the Candy Cane forest, through the sea of swirly twirly gum drops, and then I walked through the Lincoln Tunnel." The trails here are twisty, gooey, flowing single tracks that open into picturesque views of vistas, overlooks and meadows with rocks, flagstone and stumps acting as natural obstacles. When you cruise down the Wapiti Trail, you are zooming into the seven levels of the wildflower forrest and your tires are sticking like half "sucked-on" gum drops to the grippy, tacky trail surface...like pizza sauce clings to a white blouse. Your eyes start to tear from the breeze, and it's so quiet, you can actually hear the echo cries of a Canyon Wren and your stretching cheek skin as a smile rips across your face. Then you do it all over again.

I spent all day here on the Wapiti Trail and Ponderosa Loop, about 8 miles total, in mid-May. I…read morethink it is a great trainer trail close to Boulder, easy to get to to acclimatize and prepare for mountain trails. It was a beautiful hike, and we got to see some mule deer, which I had not expected. The downside is, despite all their bitching about how rocky the trail is, Wapiti is heavily used by mountain bikers, so you will quite frequently have to get off to the side to let them by. If you are looking for some peace, you may not find it as the avalanches of sweating and grunting macho bikers pump past you. I would use this as a training and exercise trail - save your bliss for the the real mountain trails where bikers are banned or unable to compete with hikers.

You can also connect to many trails north, west, and south! A true crossing of people. With massive Red Rocks and lots of nature, you can do a great amount of exploring here. There's two lots for parking, one off Canyon, or you park on Arapahoe and walk over. Most folks enjoy doing the rocky scrambles near the beautiful sandstone outcrops. They are similar to Garden of the Gods or Red Rocks Amphitheater! Several trails wind around the rocks allowing for plenty of views. You can even find an old foundation on a cliff! If you want to make an adventure out of it, try heading up Anemone Loop for a beautiful forest jaunt! It took me around 2 hours at a moderate pace with plenty of options for exploring.

This is an easy yet nerve-wracking hike. Sections of the trail are slick, so the entire time you…read moreare climbing up you're kinda concerned "how am I gonna get back down??" As it turns out, when you reach the top, there are other trails you can take down. The one closer to the creek is notably less slick and less steep. I unfortunately do not remember the name. Once you get to the top though, wow! Gorgeous views of Boulder and the surrounding foothills. Climbing on the rocks at the top is pretty fun too. Overall this was probably the most "scary" hike I did while in Boulder (but not the most demanding) because it is less maintained than the Eldorado Canyon State Park and the Rocky Mountain trails that I did. But it is still pretty easy, just a bit slippery. Use hiking sticks and you should be fine. I think this is a must do when in Boulder.

Plenty of trees and benches around the perimeter ensures that your visit is a pleasant one if you choose to walk the trail.

A peaceful little getaway that you don't have to drive hundreds of miles to get too.
