3-Day Thunder Lake Backpacking Trip

Take a trip to Wind Basin, one of the most stunning and crowd-free cirques in Rocky Mountain National park. Let a seasoned local guide lead you to the shores of Thunder Lake, and hike through some truly magnificent high country. Set up a base camp near Thunder Lake, and venture high into the alpine peaks, hanging valleys, and hidden cirques of the Continental Divide.

Your trip starts with a scenic drive from Estes Park to the trailhead. After a final fit with the backpacks, the hike begins. In the first two miles, you will hike past Copeland Falls – a beautiful cascade along North St. Vrain Creek. The remainder of the trek continues up North St. Vrain Creek to the camp at Thunder Lake. Camp a short distance from the lake, next to a serene meadow with breathtaking views into the high country’s snow-capped peaks. After a tasty dinner and a stunning sunset, settle in for the night.
After a relaxing morning and a hearty breakfast, depart with light backpacks for a day of hiking and exploring in the higher mountains. Hike west through an alpine basin thick with thousands of wildflowers and up to the Continental Divide. The Lake of Many Winds sits very near the Divide below Boulder-Grand Pass. Hike around the lake and up to the pass for views into the lush, western side of Rocky Mountain National Park. If your group’s up for it, go for a summit attempt of the 12,420ft tall Tanima Peak.
After a relaxing morning and a big breakfast, break camp and begin your hike back to the trailhead. You’ll hike a slightly different trail on the way back that takes you along Ouzel Creek, past Ouzel Falls and Calypso Cascades, both Rocky Mountain water features well worth seeing. Ouzel Falls is a sheer waterfall about 50 feet high, and Calypso Cascades is a beautiful stretch of tumbling water in a thick Lodgepole Pine forest. Arriving at Wild Basin Trailhead marks the end of your backpacking trip; after a short shuttle ride back to Estes Park, your guides will drop you off at your hotel, where warm showers await you!

4-Day Thunder Lake Backpacking Trip

On the four-day hiking trip to Thunder Lake RMNP, you’ll head off-trail to the South Fork of North St. Vrain Creek. Enjoy a gorgeous 5-mile hike for additional opportunities to see marmot, pikas and bighorn sheep. Spend a day off the beaten path, hiking to the majestic Mertensia Falls waterfall. Your full 22-mile hike is brimming with mountain views and rewarding climbs!

After breakfast, head for an off-trail hike up the South Fork of North St. Vrain Creek. After traversing into the valley, reach Mertensia Falls, a waterfall that thunders down through steep drainage. Continue hiking up the valley and you’ll arrive at Box and Eagle Lakes, which reside below the Continental Divide. Wildflowers are abundant throughout this entire hike, as are opportunities to see marmot, pikas, and bighorn sheep. Eat lunch with a view before turning back and making your way to camp.

Can’t go wrong with this one!

Lisa M. (source: Wildland Trekking)

If you want to get away from the crowds, into the beautiful backcountry, this is a great choice! The first day is difficult, no doubt, but worth the effort. The scenery was amazing and you also get to hang out with like-minded travelers who quickly become new friends.

Couldn’t Be More Happy With This Trip

Zack S. (source: Wildland Trekking)

I couldn’t be more happy with the experience my daughter and I had. Everything was amazing! Our guides Charles and Zion both were very knowledgeable and very fun to be around. They both went out of their way to make my daughter and me comfortable. The views and experience were great, but Charles and Zion both made the trip awesome!

Tamar G. (source: Wildland Trekking)

The Rocky Mountain Thunder Lake backpack was a wonderful way to ease into backpacking. The pre-trip information and communication were great. The equipment was modern and top-notch. Our guide, Floyd, made his love of the mountains known and took good care of us- keeping us dry whenever possible, preparing well-thought-out and tasty and nutritious meals and snacks, and adjusting the hikes to the weather and our abilities and preferences. I felt safe and cared for, but still adventurous and prepared for my next outdoor experience.
