Whistler is a mountain town, but on a warm summer day it is the lakes in Whistler that fill up first. Five of them sit right in the valley, linked by a paved trail. Higher up, glacier-fed lakes wait at the end of forest paths and alpine climbs.
Some are for swimming and lazy afternoons on a dock. Others are for paddling at first light, or a long hike that ends somewhere quiet and cold. Between them, you could spend a week here and never visit the same shoreline twice.
This guide covers ten lakes, from the easy valley beaches to the remote alpine ones. Start with the comparison table, then read the notes on each. Where we have a full guide, the lake links straight to it.

Valley Lakes in Whistler
The five valley lakes run in a line through town. The paved Valley Trail connects them, so you can walk or cycle between them in an afternoon. These are the lakes for swimming, paddling and picnics.
Alta Lake
Alta Lake is the largest and most loved of the valley lakes. Rainbow Park on the west shore has the main beach, a long dock and views straight across to Whistler and Blackcomb. Lakeside Park on the east shore is where you rent a canoe or paddleboard.
Mornings are calm and glassy, before the afternoon breeze picks up. Our Alta Lake guide covers every beach, the parking rules and the best times to go.
Lost Lake
Lost Lake is the closest lake to Whistler Village, a short walk through the forest. Wide gravel trails loop around it. The water warms up faster than the bigger lakes, which makes it a favourite summer swim.
There are small beaches, a dock and a grassy area for lying in the sun. In winter, the trails become cross-country ski routes. The full Lost Lake guide explains the loop and how to get there.
Alpha Lake
The Lake sits at the south end of the valley, close to Creekside. Alpha Lake Park has a beach, a dock and a playground. It is quieter than Rainbow Park and well suited to families.
Seasonal pay parking applies here in summer, as it does at the other main lake parks.
Nita Lake
Nita Lake is small and peaceful, tucked beside Creekside and the old train station. The Valley Trail runs along its shore. It is better for a slow walk at golden hour than a swim.
Green Lake
Green Lake is the biggest lake in the valley, at the north end of town. Its colour comes from glacial silt, and it shifts from jade to milky green through the summer. Floatplanes take off and land here, which makes it a striking place to watch.
The water stays cold and public access points are few. Most people enjoy it from the Valley Trail or on a scenic flight.
Alpine Lakes Near Whistler
The alpine lakes take more effort, and they reward it. Most are glacier-fed, which gives them their colour. Swimming is for the brave, since the water stays very cold even in August.
Cheakamus Lake
Cheakamus Lake is the easiest alpine lake to reach. A gentle forest trail leads to a long, deep turquoise lake inside Garibaldi Provincial Park. The effort is small and the reward is huge.
The trailhead sits at the end of a rough gravel road. Our Cheakamus Lake guide covers the drive, the trail and camping at the lake.
Callaghan Lake
Callaghan Lake is a drive-up alpine lake in the Callaghan Valley, west of Whistler. A forest road climbs to a quiet shoreline ringed by peaks. It is ideal for a canoe, a slow afternoon or a night at the campsite.
The road is rough in places and opens later in the season. The Callaghan Lake guide explains road conditions and what to bring.
Rainbow Lake
Rainbow Lake sits in an alpine basin above the west side of the valley. Reaching it is a full-day hike of around 16 kilometres return. The lake feeds Whistler’s drinking water, so swimming, dogs and camping are not allowed.
It is one of the most rewarding hikes in the area. Read our Rainbow Lake guide for the trailhead, parking and trail notes.
Cirque Lake
Cirque Lake is the most remote lake in this guide. You paddle across Callaghan Lake, then climb a steep, rugged trail to a hanging lake below the cliffs. Few people make it, which is the point.
Only attempt it with paddling experience and settled weather. Our Cirque Lake guide walks you through it.
Garibaldi Lake
Garibaldi Lake sits in Garibaldi Provincial Park, south of Whistler toward Squamish. It is one of the most famous views in British Columbia, a vast turquoise lake below glaciers. The hike in is long and steady, around 18 kilometres return.
Check BC Parks advisories before you go, including any day-use pass requirements.
Swimming in Whistler’s Lakes
The valley lakes are warmest from mid-July to late August. Lost Lake and Alpha Lake usually warm up first. Alta Lake follows, while Green Lake stays cold all summer.
There are no lifeguards at most lake parks, so swim within your limits. Glacial lakes can cause cold shock, even on hot days. A quick-drying microfibre towel is worth packing for lake days.
Paddling and Lake Activities
Canoes, kayaks and paddleboards can be rented at Lakeside Park on Alta Lake. Paddle the River of Golden Dreams from Alta Lake toward Green Lake for a gentle river trip. Guided paddling tours and other experiences are listed in the OneLife Viator shop.
Travel insurance that covers water sports and hiking is worth arranging before you go. A plan through World Nomads covers both.
Parking at the lake parks. Seasonal pay parking runs at Rainbow, Lakeside, Wayside and Alpha Lake parks from 15 May to 15 September, between 10am and 6pm. Check current rates on the Resort Municipality of Whistler website, or walk the Valley Trail instead.
When to Visit Whistler’s Lakes
July and August are the classic lake months, with warm water and long evenings. June is quieter, though the alpine lakes may still be frozen or snowbound. September brings cooler water, golden light and fewer people.
In winter, the valley lakes freeze and the trails around them turn to snowshoe and cross-country routes. The alpine lakes are out of reach until the next summer.
Where to Stay Near the Lakes
Whistler Village puts you closest to Lost Lake and within an easy ride of Alta Lake. Creekside sits near Alpha Lake and Nita Lake, with a quieter feel. Our guide to where to stay in Whistler compares both areas.

Final Thoughts
The lakes in Whistler are where summer really happens. A morning paddle on Alta, an afternoon swim at Lost Lake, a long hike to Rainbow. Each one shows you a different side of the valley.
Start with the easy ones close to town. Then follow the trails higher, toward the quieter, colder water.
Bring a towel. You will want to get in.
