Colorado
Four parks. Three weeks.

Drive south on I-25 and west through the US 160 corridor into the San Luis Valley, choosing stops around the actual road conditions. The broad valley and snow-lined Sangre de Cristo range introduce a very different Colorado from Denver.

Settle into the dunes gateway for two nights. I keep this as a travel-and-arrival day, with an optional short evening look toward the mountains if time and energy allow.

Start early for a hike among the dune ridges. There is no single marked route through the dunefield, so I would agree a manageable out-and-back objective and turn around with enough energy for the return across soft sand.

High Dune on the first ridge can be a goal if conditions and fitness suit. Return before the sand heats up, with time to explore the Medano Creek margin if it is flowing. This one full park day combines the dunefield and creek; runoff is seasonal, not guaranteed.

Build the day around a reserved ranger-led Cliff Palace tour when it is offered on the chosen date. The alcove, masonry rooms and open kiva courts give the architecture a scale that distant viewpoints cannot.

Allow the full in-park drive and the tour’s ladder and stair requirements. I would pair the visit with the museum and a few mesa-top overlooks, with time to understand Ancestral Pueblo communities and their living descendants.

Reserve a second cliff-dwelling experience at Balcony House if its tour is running and the physical requirements suit. Its courtyard, passages and ladder access offer a different encounter with the architecture.

This tour includes tall ladders, a tight crawl-through and exposed steps. I would discuss those features before choosing it; another available ranger tour or an overlook-and-museum day can be the better fit. The artwork shows an alcove view, not permission to enter closed rooms or kivas. If time, conditions and energy suit, consider a short mesa-top walk afterwards; the rugged 2.4-mile Petroglyph Point loop is optional, not something to rush after the tour.

Drive through Durango and north on US 550 toward Silverton, allowing a full scenic travel day for the mountain passes. Choose the stops around road conditions and daylight rather than adding a demanding hike to the transfer.

Spend the night in Silverton. Walk the historic streets, find dinner and enjoy the snowcapped mountains around town. In June, high San Juan trails can still hold substantial snow, so this stay leaves room for local walking without promising access to every alpine route.

Use the middle day to enjoy Vestal Basin and views of Wham Ridge on Vestal Peak, with Arrow Peak and the Grenadier country around it. This is the hiking and backpacking visit I want: time to look up, explore suitable terrain and return to camp without a summit objective.

The upper approach is steep and rough, with navigation, snow and creek conditions to assess. Avoid entering hazardous snow slopes just to reach a viewpoint. Use existing durable camps, observe the water setbacks and food-storage rules, and do not build a wood fire in Vestal Basin. The second wilderness night leaves room to enjoy the setting.

Follow the Million Dollar Highway stretch of US 550 from Silverton toward Ouray, with snowcapped peaks above the road. The mountain walls, Red Mountain country and changing views deserve an unhurried daylight drive with stops at established pullouts, chosen around current conditions.

This is a demanding mountain road with exposed sections. I would choose a fair-weather daylight window, keep the day flexible and use an alternate route if conditions make that the sensible choice. Arrive in Ouray for the first of two nights.

Stay in Ouray for a full day after the backpack and Million Dollar Highway. Choose a suitable section of the Perimeter Trail in the morning, checking current access, then leave the afternoon for the Ouray Hot Springs Pool.

I like this change of pace: warm mineral water, mountain walls above and an evening in town without another drive. Check the pool’s dated hours, admission and maintenance notices; the soak is planned but no ticket is booked.

Continue toward Montrose and the South Rim of Black Canyon of the Gunnison. Make an afternoon introduction at the visitor center and selected overlooks, using only the road sections open for the season.

The narrow canyon and Gunnison River far below create a different sense of scale from the San Juans. Stay in Montrose so there is another morning for a hike or a viewpoint before continuing north.

Start the Rocky Mountain chapter around Bear Lake, with the right park-entry and Bear Lake Road arrangements for the actual dates. Take the short approach and walk what conditions allow around the lake.

June opens up more walking possibilities, but shaded trails and higher sections may still hold snow and ice. Add Nymph or Dream Lake if current reports and footing suit. Bear Lake itself is a place to walk and look: swimming and bathing are prohibited there.

I would consider two designated campground nights within this five-night stay. Explore camping in Rocky Mountain National Park ↗ for the options, preparation and reservation details.

Give Lake Haiyaha its own hiking day. The standard Bear Lake approach is about 4.2 miles round trip with roughly 745 feet of elevation gain. June is a better seasonal fit than May, but snow on shaded traverses and the boulder approach can still make this a demanding mountain outing. Check current reports, closures and ranger advice before choosing the route.

I would love to take the plunge in the lake if the actual conditions allow. The illustration captures that wish with an anonymous jumper, rather than recommending a jump from the boulders. Any swim is a separate, on-the-day decision about cold water, ice, rocks, a suitable exit and current restrictions; a lakeside pause remains rewarding without water entry. The groundwork below sets out the precautions.

Plan a dedicated Trail Ridge Road driving day, taking advantage of June’s better chance of through access. With the road open and weather suitable, drive from Estes Park toward the Alpine Visitor Center and Milner Pass, adding established overlooks and short open trails for sweeping mountain views. Return to the Estes base rather than combining the high road with a long transfer.

The road usually opens around late May, but snowstorms and temporary closures can still affect June. Check the park’s road status before departure and move this outing to the flexible day if needed. Short alpine walks depend on open trails, snow and wind; an open road does not mean every high trail is ready.

Keep the last full park day for the best opportunity: a postponed Trail Ridge drive or Haiyaha hike, an open lower Fern Lake route, or a wide-view walk in Moraine Park. This is the useful flexible day within the five-night base.

I like having a day that can respond to the place. It turns a change in weather into a choice rather than a failure of the schedule, and leaves room to stay with the part of the park that has caught my attention.
