Boulder Colorado Mount Sanitas Trail

Boulder’s Sanitas Trails are just .5 mile west of 4th Street on Mapleton. Don’t be fooled by the parking along Mapleton, or the lack of it as you approach the trailhead because there’s trail head parking on your left just beyond the start of the trail.

Both the Sanitas trails are great routes. The valley is heavily used and consequently favored by locals as dogs are allowed. Remember the rules: All dogs must be leashed in the parking lot and trailhead area. Beyond the trailhead leash area, dogs must be on a hand-held leash unless they meet the voice and sight control standard and display a City of Boulder Voice and Sight tag. Dog excrement removal is required by law.

A dog station is available to aid in the collection of dog excrement.

Whether you take the relatively easy hike up the valley, or choose the Mount Sanitas trail along the ridge, both end up at the north overlook with a wonderful view of Boulder and all the way out to the edges of Boulder County.

Sanitas Valley Trail is a wide, graveled trail heading north up the valley between the Hogback Ridge and Mount Sanitas.

At the ‘end’ of the trail you can access the Dakota Ridge Trail to the east, the Mount Sanitas Trail to the west, the Hawthorne Trail near its northeast end, and the East Ridge Trail at its northwest end.

It’s a relatively easy walk that only takes a short while for most folks, especially if you’re acclimated to the local altitude. If you’re not, but reasonably fit (can walk a few blocks in your home town without distress) this is a great place to take an easy hike and get some great views.

Mount Sanitas Trail is considered moderate to difficult which runs along both sides of the ridge leading to the summit of Mount Sanitas.

The southern portion of the trail, not far from the trail head  is used as an access by climbers to several bouldering areas along the trail.

Access points to these bouldering areas are pretty clearly marked and the Boulder Open Space and Mountain Parks folks ask that you only boulder in the designated areas.

This trail also provides beautiful views to both the east and west. It’s worth the trip if you’re reasonably fit, but don’t take your in-laws from the low lands up here in their loafers!

The trail was names for the old sanitarium (sometimes referred to as the health spa) located near the trail head.

The building was subsequently Boulder’s Mercy Hospital, and is now the Mapleton Medical Center which is owned and operated by Boulder Community Hospital.

The Mount Sanitas and Sanitas Valley trails are very popular with locals due to the close proximity to town, and for the fact that the Sanitas Valley trail is dog friendly. Now, if we could get everyone to use the doggie poop bags and put them in the receptacle, it would be even better!
