ITINERARY
Day 1
- Shuttle to trailhead: 30 minutes
- Hiking Mileage: 6.8 miles
- Elevation Gain: 2,250 feet
This Rocky Mountain National Park backpacking trip starts with a scenic drive from Estes Park to our trailhead. After doing a final fit with the backpacks we begin our hike. In the first two miles we hike past Copeland Falls – a beautiful cascade along North St. Vrain Creek. The remainder of our trek continues up North St. Vrain Creek to our camp at Thunder Lake. We’ll 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 we’ll settle in for the night.
Day 2
- Hiking Mileage: 6+ miles day hiking
- Elevation Gain/Loss: 1500 feet
After a relaxing morning and hearty breakfast we’ll depart with light backpacks for a day of hiking and exploring in the higher mountains. We’ll hike west through an alpine basin thick with thousands of wildflowers and up an alpine lake perched near the Continental Divide. We’ll hike around the lake and (for those who want an additional challenge) up to the pass for views into the lush, western side of Rocky Mountain National Park. If the group is really ambitious, we can continue on for a summit attempt of Tanima Peak (12,420 Ft.)
Day 3
- Hiking Mileage: 5+ miles
- Elevation Loss/Gain: 1,250+ feet
Day 3 is often remembered as the highlight of this trip. After breakfast we begin our hike off trail up the South Fork of North St. Vrain Creek. After traversing into the valley we’ll come to Mertensia Falls, a waterfall that thunders down through a steep drainage. As we continue hiking up the valley we 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. We’ll eat lunch with a view before turning back and making our way to camp.
Final Day
- Hiking Mileage: 6.8 miles
- Elevation Loss: 2,250 feet
- Shuttle to Estes Park: 30 minutes
After a relaxing morning and a big breakfast we’ll break camp and begin our hike back to the trailhead. We’ll hike a slightly different trail on the way back that takes us 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. Our arrival at Wild Basin Trailhead marks the end of our backpacking trip; after a short shuttle ride back to Estes Park we’ll drop you off at your hotel where warm showers await you!

This was an amazing trip!
This was one of the best trips, with the most exquisite views I have ever taken. Day 1 is just a beating of a hike, but it allows you to get a great nights sleep in preparation for the next few days. Our guide for this trip, Tamera, was so amazing and full of information. We asked a wide range of questions and she was able to answer almost all of our questions. Our group had a mix of abilities and Tamera was able to ensure we all had the greatest experience possible. I think she was Mother Nature reincarnated. She would schedule our arrival back to base camp just as the sky let loose with a torrential rainfall every day. Not once did we get caught up in a rainstorm outside of base camp.

First backpacking trip - will not be the last
First time backpacking and I am so glad I chose Wildland and was so lucky to have Sean & Leah as our guides for this trip at RMNP. I was initially nervous about the weight of the pack + the elevation increase on the first day since I was coming from sea level. Drinking a ton of water prior to the trip and during was key as well as having such experienced , knowledgeable and fun guides helped so much. Both were great about checking in, encouraging and staying positive, pushing us when needed. Anyone who gets to trek with them is lucky, I can't stress that enough! They were so so helpful , patient and fun to share this experience with!! The food was wonderful - great creative meals. I probably ate better & healthier during this trip than at home. Thanks chef(s) I will recommend taking the training description seriously as there was some strenuous bits of some of the hikes- I could have spent more time training with heavier packs, but either way our group got through it and even if I was dead tired each evening, it was an amazing sense of accomplishment to get through the trip (with our guides help!) I really loved this experience , particularly being so detached from regular real world stresses - no phone service and just focusing on the present and what's in front of you is a beautiful experience in a beautiful place. I am already plotting my next Wildland trip!!
