Coldwater Canyon and the trail door at 2750 North.

At 2750 North Mountain Road, and its published name is the Pioneer Trailhead. That is the Bonneville Shoreline Trail Committee's own name for it in the trailhead list it publishes for this stretch, where it is the third trailhead southbound. The address geocodes inside North Ogden city at the U.S. Census Bureau, read 21 August 2026, and a U.S. Geological Survey point query at the same coordinates returns 4,742 feet. It is 1.52 miles from city hall in a straight line. No fee, permit, gate hour or capacity figure is published for it by any body.

No. Two point in place probes in the drainage between the Pioneer Trailhead and the Ogden Nature Center North Trailhead, run at the U.S. Census Bureau's address geocoder on 21 August 2026, both returned no incorporated place. The trail organisation that built the path there says the same thing from the other direction: its own segment write up records that the route stays on Forest Service and State land. What North Ogden holds here is the trailhead and the street access, not the canyon. The probes land in the reach the trail committee identifies as the canyon detour rather than at published canyon coordinates, because no issuing body published any.

Because a private landowner closed access to it, and the trail committee prints that in its own words: because a private landowner has closed off access to the road that goes up Coldwater Canyon, it is necessary to follow a detour along Mountain Road to the next trailhead. No date for the closure is published by anyone, and no North Ogden City page, Weber County page or Forest Service alert about it was found. The underlying reason the trail runs where it does is on the record too: the trail organisation says it worked for years to negotiate a lower route through private property and eventually resorted to a route on federal and state ground. No landowner is named here because no source read named one.

Along Mountain Road, between the Pioneer Trailhead at 2750 North, which is in North Ogden, and the Ogden Nature Center North Trailhead at 1180 North Mountain Road, which geocodes to Ogden. Those two are consecutive on the trail committee's southbound trailhead list for this region, which is what fixes the detour's two ends. A walker covering the whole stretch is on a road rather than on trail for that section. The trail committee's page carries its own warning that some trail details on it may not be up to date.

Two bodies publish two answers three miles apart and neither is preferred here. The Forest Service record for Coldwater Canyon Trail 325, updated 17 June 2025, gives 4.5 miles and lists day hiking, horseback riding and mountain biking in the Ogden Ranger District. The Trails Foundation of Northern Utah's own record gives 1.30 miles, rates it moderate, allows hiking and dogs but not bikes or horses, and describes a route along the canyon bottom past an old Civilian Conservation Corps camp. The plain reading is that one is a lower segment and the other the whole trail, but nothing published says so.

A street end car park at the top of Mountain Road, with no published capacity, no published fee and no published hours. The nearest facilities are at Equestrian Park, 2675 North Mountain Road, 0.02 miles away on the coordinates used here, which the city lists as 8.6 acres with a disc golf course, an equestrian arena, a pavilion, a drinking fountain, electricity and restrooms. The city does not publish any relationship between the park and the trail, so none is asserted here; the two simply sit at the top of the same street.

On the segment the trail foundation records from this trailhead, yes to both. Its record for the segment running from 2750 North toward the canyon gives 2.40 miles, rates it moderate and lists hiking, biking, horseback riding, snowshoeing, dogs, families and electric bikes among its uses. That is a broader permission set than the steep canyon paths above Ogden five miles south carry, which are hikers only. No elevation gain figure is printed here for any of these segments because the trail organisation's own gain and high point fields did not extract cleanly in this pass.

No. The northern anchor of the record stretch is a different trailhead further north, in the next city, and it belongs to that city's own pages rather than to this one. What the Pioneer Trailhead offers is a door onto the quiet middle of the run, on bench grade rather than canyon grade, five miles north of the crowded canyon trailheads inside Ogden. The full picture of that trail, its mileage, its segments and its two remaining gaps sits on the region's page on Ben Lomond and the Ogden bench.

Two, and neither is the canyon. Equestrian Park at 2675 North Mountain Road is 8.6 acres and is the city park nearest the bench, with the arena, the disc golf course and the restrooms. Lakeview Park at 3550 North 350 East is 24.3 acres, the largest in the city's own list, and its amenity line reads nature walking trails, access to canal trail. The canal trail is not named on the city's page and no separate page for it was found in this pass, which makes it one of the open questions this companion keeps rather than answers.
