The website

PeakBucket isn't just another online summit log; we're a data tracking and visualization website that's been crafted to meet the specialized needs of modern peakbaggers. Everybody has peaks and lists; here are a few additional things that PeakBucket has to offer:

More than peaks

Peakbaggers love data, and there's more of it to love on PeakBucket. Our activity-based platform enables you to record common GPS statistics, including distance and elevation gain (in both metric and imperial units), along with the peaks you summit.

Not just one-and-done

Lists aren't one-time checklists. Whether your goal is to finish that list once or twelve times, our completion styles automatically track your list progress against all season, winter, four season and grid finishes.

Interactive maps and graphs

Data's more fun when you can interact with it. That's why PeakBucket provides data visualizations to review your peakbagging activity and list progress data in a format that's engaging and pleasing to the eye.


Peakbaggers are social. We've made it easy to share your peakbagging activity and list progress with like-minded people on PeakBucket and other websites.

On the go access

Laptops are heavy and Wi-Fi can be scarce. PeakBucket's responsive platform provides a seamless user experience on most mobile phones and tablets with a data connection so you can easily record, review and share your peakbagging activity and list progress closer to the mountains.
