The Rainbow Trail is one of Colorado's oldest long-distance trails, dating to 1912 when the newly formed U.S. Forest Service built it to access grazing allotments in the Sangre de Cristo Mountains. Spanning 100+ miles from Poncha Pass south to Music Pass near Great Sand Dunes National Park, the trail arcs along the eastern flank of the Sangre de Cristos at an average elevation of 9,000 feet, earning its name from this rainbow-like curve.
This is a trail for backpackers seeking a quieter alternative to the Colorado Trail. You'll ramble through ponderosa forests and alpine meadows, cross mountain creeks with bridge crossings over larger waterways, and enjoy constant views of the jagged Sangre de Cristo peaks rising to the west. The trail skirts the boundary of the Sangre de Cristo Wilderness, with numerous side trails accessing the high country. Water is adequate but requires planning—expect to carry more than usual as some stretches have dry creek beds depending on season. Wildlife is abundant, making proper food storage essential.
The Rainbow Trail welcomes multiple users: hikers, mountain bikers, and motorcyclists share most sections (though motorized users are prohibited in wilderness areas). Thru-hikers typically complete the trail in 5-7 days, though the trail's many access points make it ideal for section hiking weekends.
No permits are required for backpacking the Rainbow Trail. The trail travels through Pike-San Isabel National Forest where dispersed camping is allowed outside developed campgrounds as long as you don't cause resource damage and follow these rules:
Bear Country Requirements: The Rainbow Trail is in active bear habitat. While bear canisters are not mandatory, you must store all food and scented items in a bear-resistant manner. Bear bags, bear boxes, and storage in hard-sided vehicles are acceptable methods. Pop-up campers, tents, and open-top vehicles do not qualify as bear-safe storage.
Fire Restrictions: Check current conditions before departure. During periods of high fire danger, campfires may be prohibited outside developed recreation sites. Fire restrictions vary by ranger district (Salida and San Carlos districts manage most of the Rainbow Trail). Current fire status is available through the Pike-San Isabel National Forest website.
Wilderness Areas: Where the trail borders the Sangre de Cristo Wilderness, standard wilderness regulations apply—no motorized equipment, no mountain bikes, and Leave No Trace principles in effect.
July through September offers the most reliable conditions, with July being the busiest month. The trail typically becomes snow-free by late June, though higher elevation sections and north-facing slopes can hold snow into early July following heavy winter snowpack.
Peak wildflower season runs from late June through August, with meadows exploding in color after good summer rainfall. Alpine blooms peak in July and early August.
Fall colors arrive in late September through early October as aspens turn golden against the evergreen forest backdrop. This is an excellent shoulder season with fewer crowds, though nighttime temperatures drop significantly and early season snowstorms are possible, especially above 10,000 feet on side trails.
Spring (May-June): Snow lingers at higher elevations and many trailheads require 4WD due to muddy road conditions. Creek crossings run high with snowmelt. Some sections may be passable for experienced spring hikers, particularly the lower elevation stretches near Salida.
Winter: The trail is occasionally used for snowshoeing, but is not maintained for winter travel and many trailhead access roads close seasonally (like Music Pass Road). Avalanche hazard exists on adjacent peaks.
Monsoon season (mid-July through mid-August) brings daily afternoon thunderstorms. Expect rain for 1-2 hours most afternoons, typically between noon and 3pm. The primary hazard is lightning rather than rainfall itself. Plan to camp in protected locations by early afternoon and avoid exposed ridgelines when storms build.
Water is adequate but not abundant—plan to carry 2-3 liters between sources. The trail crosses six major creeks with bridges, plus numerous smaller drainages. Backpackers report water is "plentiful in just enough places" but expect some dry creek beds, especially in late summer and fall. Specific advice from trip reports: fill up at the first streams around mile 1.5 on certain sections, as accessible water may not appear until mile 4.5 or beyond.
Water reliability by season: - Spring/early summer: All sources running strong, sometimes dangerously high during peak snowmelt - Mid-summer: Most sources reliable, though smaller tributaries may slow to trickles - Late summer/fall: Many smaller drainages dry; plan for longer water carries between reliable creek crossings
Always treat water from streams and lakes. Wildlife concentration near scarce water sources means higher contamination risk.
Resupply options:
Salida (mile 12-20 depending on route): Full-service town with Safeway grocery, Walmart (few miles outside town), outdoor outfitter, post office, restaurants, hotels, and laundromat. Salida sits approximately 15 miles east of where the trail crosses US Highway 50. This is the primary mid-trail resupply for northbound or southbound thru-hikers.
Poncha Springs: Located on the western outskirts of Salida near the northern terminus. Offers cheaper lodging than Salida, plus full grocery and hardware stores.
Westcliffe (near southern terminus): Full services available in this small mountain town, though it's not directly on the trail. Accessible via Music Pass Road trailhead area.
Coaldale and Cotopaxi: Small mountain communities between Salida and Hayden Creek offering basic accommodations but limited resupply options.
No commercial mail drop services are prominently advertised for the Rainbow Trail. Thru-hikers typically resupply in Salida or carry food for the entire journey if completing the trail in under 7 days.
Lightning exposure: The trail generally stays below treeline at 9,000 feet, but several connecting trails climb to exposed ridges and 13,000+ foot peaks. During monsoon season (mid-July to mid-August), afternoon thunderstorms are nearly daily. Follow the "treeline by noon" rule if climbing peaks, and even on the Rainbow Trail itself, avoid ridge crossings in afternoon when storms build. Lightning risk decreases significantly in September.
Creek crossings: The six major creeks have bridges, but smaller drainages require rock-hopping or wading. During peak snowmelt (late May through June), even bridged crossings can be treacherous with high water. Creek crossings present minimal danger by late summer when many smaller tributaries go dry.
Navigation: The trail is generally easy to follow but "isn't well marked" according to multiple trip reports. Download maps and GPS tracks before departure. The trail's many intersections with side trails require attention to navigation, especially where motorized routes diverge.
Bear activity: Black bears are common. Proper food storage is mandatory. Camp away from water sources where wildlife concentrates, especially during dry periods when water is scarce.
Terrain: The trail surface varies from smooth forest floor to rocky, cobbled sections with roots. Footing requires attention in rugged stretches. The trail is rated as "highly challenging" for the full distance, though individual sections vary significantly in difficulty.
Motorized users: The Rainbow Trail allows motorcycles on most sections (though motorized use is prohibited in designated wilderness). Be prepared to encounter dirt bikes, especially on summer weekends. Motorcycles must stay on designated routes and are far less common than hikers and mountain bikers.
Wildfire: Colorado's increasing wildfire activity means potential closures during fire season. Check COTREX app or Pike-San Isabel National Forest alerts for current closures before departure. Recent fire mitigation projects in some areas have thinned forest to reduce future fire risk.
No recent major reroutes reported, though always verify current conditions as fire damage can necessitate temporary closures or detours.
Airports: - Colorado Springs (COS): 80-107 miles depending on trailhead, 2-2.5 hour drive to most access points - Denver International (DEN): 115-165 miles, 2.5-3 hours to northern trailheads, longer to southern access - Pueblo Memorial (PUB): 62 miles from Westcliffe/southern terminus
Rental cars are available at all three airports. High-clearance vehicles are recommended for some trailheads.
Northern Terminus (Poncha Pass area): From Salida, take US Highway 285 northwest toward Poncha Pass. The Rainbow Trail trailhead is located just past Mears Junction, with parking on the west side of Highway 285. This section is accessible by 2WD vehicles.
Hayden Creek access (mid-trail, popular section hiking start): From Coaldale on US 50 (southeast of Salida), turn southwest on County Road 6 and drive approximately 4.5 miles. Road conditions are generally good, though they deteriorate during wet weather. 2WD vehicles can typically access this trailhead when dry.
Southern Terminus (Music Pass): From Westcliffe, take Highway 69 south for 4.5 miles and turn west at the Music Pass/South Colony Lakes sign. Critical: 2WD vehicles must park where the Rainbow Trail crosses Music Pass Road (adding 2.5 miles each way to any hike). 4WD vehicles can continue another 2.5 rough miles to Music Pass Trailhead. This last 2 miles requires high clearance. Music Pass Road closes seasonally, typically opening June 1.
Bear Creek Trailhead (northern section near Salida): Accessed via County Road 101. The last 2 miles require high-clearance vehicles. Road conditions worsen during wet weather.
Shuttle logistics: No commercial shuttle services are prominently advertised for the Rainbow Trail. Thru-hikers typically arrange their own vehicle shuttles or coordinate with hiking partners. The 100+ mile distance between northern and southern termini makes shuttle drives lengthy (3+ hours). Uber/Lyft availability is extremely limited in this rural area.
Parking: Most trailheads offer free parking. No permits required for parking. Verify that trailhead roads are open before departure, especially in spring when mud and snow can close access roads.
Section hiking strategy: The Rainbow Trail's many access points make it ideal for section hiking. Popular sections include Hayden Creek to Bear Creek (12.5 miles) and the Music Pass area for access to Great Sand Dunes backcountry. Plan sections based on available water sources.
Camp selection: Since you must camp 100+ feet from water and wildlife concentrates at water sources during dry periods, identify camping areas on maps before departure. Flat spots exist in meadows and forest clearings, but terrain can be sloped in places.
Timing for thru-hikers: Most backpackers complete the trail in 5-7 days. Starting at northern terminus (Poncha Pass) heading south means afternoon sun at your back, though prevailing weather patterns move west to east.
Side trip opportunities: The trail intersects numerous paths into the Sangre de Cristo Wilderness, including routes to Music Mountain, Spread Eagle Peak, and other 13ers. Cottonwood Trail, Comanche Trail, Goodwin Trail, and Venable Trail all connect from the Rainbow Trail into high country.
Wildflower timing: For best blooms, aim for late June through early August following good rainfall. Meadows burst with color in July.
Fastest Known Time: Ultra-runners have completed the trail in under 2.5 days (one FKT is 2 days, 7 hours, 27 minutes for 108 miles), demonstrating the trail's runnable character in many sections.
Combination routes: The Rainbow Trail can be combined with the Colorado Trail for a 325-mile traverse from Westcliffe to Durango, creating one of Colorado's premier long-distance backpacking routes.
Current conditions: Check Pike-San Isabel National Forest website or call the Salida Ranger District before departure for fire restrictions, trail conditions, and seasonal closures. The COTREX app provides real-time trail alerts including wildfire information.
