Don MacGregor’s Slideshow

Day 1. Float Trips Ashcroft to Spences Bridge

Using large, pontoon platform rafts perfect for all ages, the first day of Kumsheen’s Naturalist Outing introduces you to the natural environment between Ashcroft and Spences Bridge. More than sixty species of birds, a wide array of mammals, reptiles and insects, and a myriad of desert plants are concentrated along the river.

Day 2. Float Trip & Whitewater, Spences Bridge to Lytton

This river section is what has made the Thompson River famous. We discover the geology, flora and fauna, and learn the natural history along the valley and river corridor. The last 16 km we get immersed in the best whitewater along the river from the safety of our large pontoon rafts.


60+ Bird Species

The birding component is a highlight. More than sixty species have been identified along the river corridor, and your heart will soar when a golden eagle lifts off the cliff at 150-million-year-old Black Canyon or an osprey dives into the Thompson, emerging with a rainbow trout in its talons.

Forty years ago, only one nesting pair of osprey lived along the Thompson. The original nest has collapsed, but dozens of their offspring now inhabit the treetops between Ashcroft and Lytton.

Pukaist Village & Huge Talus Slope

There was once a large First Nations village of at least 800 people near a long talus slope on the Thompson River. Their burial ground was at the base of the slope that is now home to a collection of mammals, birds and reptiles.

Explore the Thompson By Raft

A unique feature of this natural history tour is the exhilarating experience of travelling a breathtaking river by raft. You’ll find it both energizing and stimulating – smiles and laughter are guaranteed. Plus, rafting the river opens up possibilities for us to explore areas that otherwise are nearly impossible to access.


Your Home Base

In the evenings and early mornings, when you are not on the river or exploring a side canyon, you have all the amenities of the Kumsheen Rafting Resort at your disposal. We feast on gourmet French cuisine in the Cutting Board Restaurant, recharge in a Teepee or themed Canvas Cabin, and relax around the pool or hot tub.
