Grouse Ridge Backpacking Guide: Island Lake, Penner Lake & Five Lakes Basin

One of Northern California’s Best Places for Beginner Backpacking, Day Hiking & Alpine Lakes

If you’re looking for an easy backpacking trip in Northern California or one of the best places to spend a day wandering between alpine lakes, Grouse Ridge deserves your attention. Tucked into the western edge of Tahoe National Forest, this high-country basin is filled with interconnected trails leading to places like Island Lake, Penner Lake, Five Lakes Basin and dozens of smaller lakes that invite exploration rather than simply checking off a destination.

Whether you’re planning your first overnight backpacking trip, searching for a dog-friendly day hike, or hoping to spend a quiet weekend fishing and swimming in the Sierra, Grouse Ridge offers something many mountain destinations have lost—options.

One of my favorite parts of hosting the Sierra Rec Now podcast is listening when local guides start talking about the places they recommend to friends.

Not the famous trails you’ve seen a hundred times online.

The places that come up naturally when someone asks, “If you had a free weekend, where would you go?”

That’s exactly what happened when I sat down with James and Kelsey.

Before long we weren’t talking about gear anymore. We were talking about Grouse Ridge—why they continue recommending it to new backpackers, why experienced hikers keep returning, and how one trail can turn into an entire weekend of exploring.

I’d been here before, mostly wandering the lakes with Dakota on long summer day hikes. It always felt different from many Sierra trips. There wasn’t a summit pulling me forward or a long mileage goal hanging over the day. We’d simply follow a trail until another lake appeared, stop for a while, then decide where to wander next.

After that conversation, I found myself opening the map again.

Not because I’d forgotten Grouse Ridge.

Because James reminded me that this isn’t really one destination.

It’s an entire basin worth exploring.


Why Visit Grouse Ridge?

Some places are defined by one iconic destination.

Grouse Ridge isn’t one of them.

This corner of Tahoe National Forest is a collection of alpine lakes, granite ridges, open forests and flower-filled meadows connected by an easy network of trails. Instead of committing to one big objective, you’re free to build the kind of day that sounds good when you step out of the truck.

Maybe that’s swimming in Island Lake.

Maybe it’s fishing your way from one lake to another.

Maybe it’s wandering farther toward Penner Lake or Five Lakes Basin simply because you’re curious what’s around the next bend.

That’s the personality of Grouse Ridge.

The hiking is approachable.

The scenery changes constantly.

One hour you’re walking beneath towering pines. The next you’re crossing polished granite before dropping beside another lake that feels like a perfect place to spend the afternoon.

This is also one of those rare Sierra destinations that works just as well for different kinds of visitors.

Families can spend the afternoon exploring.

Anglers can hop between lakes looking for trout.

Backpackers can create an easy overnight loop or settle into camp and spend two days exploring without ever feeling rushed.

Dog owners will appreciate the moderate grades, open trails and plenty of water along the way. It was one of my favorite places to hike with Dakota because every mile seemed to offer another excuse to stop, cool off and enjoy the day.

Weekends can absolutely be busy, especially near Carr Lake and the more popular lakes.

But here’s something I appreciate about Grouse Ridge.

It isn’t lonely.

It’s spacious.

Walk another mile.

Choose a different lake.

Visit on a Thursday evening or stay through Sunday night.

The basin has a way of spreading people out, and before long it feels like you’ve found your own corner of the Sierra.

Before You Choose a Trail…

One thing I’ve learned after years of exploring the Sierra is that I rarely decide where to go based on mileage.

I choose places based on the experience I want to have.

Can I swim?

Will there be a quiet shoreline where coffee tastes better because there’s nowhere else I’d rather be?

Is there enough variety that I won’t feel like I need to rush to the next destination?

Would Dakota have loved wandering these trails?

Those are the questions that keep bringing me back to Grouse Ridge.

This isn’t a place where the goal is to conquer a route.

It’s a place to slow down.

Spend an hour beside a lake.

Follow a trail simply because you haven’t been that way before.

Cast a line into the water.

Watch the afternoon drift by from a patch of warm granite.

With dozens of lakes connected by moderate trails, Grouse Ridge rewards curiosity more than ambition.

For me, that’s exactly what makes it special.

How I’d Spend a Weekend Here

If I only had one summer weekend, I’d probably leave after work on a Thursday.

The trailheads are quieter.

Finding a campsite is easier.

Friday morning belongs to birdsong instead of a crowded parking lot.

I’d probably make my way toward Island Lake or Penner Lake, set up camp and spend the evening fishing or wandering the shoreline before settling in for the night. The next morning would start slowly—with coffee beside the lake and no real agenda other than deciding which trail looked interesting.

That’s the beauty of Grouse Ridge.

You don’t need a rigid itinerary.

Some of the best moments happen when you simply follow your curiosity.

If I couldn’t leave until Saturday morning, I’d skip the backpack entirely.

Honestly, I think Grouse Ridge shines just as brightly as a long day hike. Throw a fishing rod in the truck, wander through the basin, enjoy lunch beside one of the lakes and head home knowing you’ve barely scratched the surface.

That’s what keeps bringing people back.

Not one famous viewpoint.

Not one bucket-list destination.

Just another excuse to spend a day—or a weekend—among some of the friendliest alpine lakes in the Northern Sierra.

Where James & Kelsey Would Take You

One of the reasons I wanted to hear James and Kelsey’s thoughts on Grouse Ridge is simple—they’re not just hikers. They spend their summers introducing people to backpacking.

These are the trips where someone carries their first overnight pack.

Where families discover they really can sleep beside an alpine lake.

Where someone who has always wondered if backpacking is for them finally finds out.

So when I asked about favorite places in Tahoe National Forest, I paid attention.

Grouse Ridge wasn’t appealing because it’s the biggest challenge.

It was appealing because it gives people choices.

You don’t have to commit to a demanding multi-day route to have a memorable weekend. You can camp at Island Lake, wander toward Penner Lake, spend an afternoon exploring Five Lakes Basin, or simply settle beside one lake and enjoy being there.

That flexibility is exactly what makes it such a strong recommendation for first-time backpackers.

James also shared something that quietly says a lot about how they approach guiding. Their trips aren’t built around pushing people to hike farther—they’re built around helping people enjoy the experience. They even teach beginners how to use bear cans on trips where they’re not required because they know those skills will matter on future adventures.

In other words, they’re not just guiding a weekend.

They’re helping people become backpackers.

After talking with them, I understood why Grouse Ridge is one of the places they keep bringing people back to.

If I were planning my first trip here, I’d happily follow the advice of guides who have watched hundreds of beginners fall in love with these mountains before deciding which trail to take on my own.

Planning Your Grouse Ridge Adventure

Best Time to Visit

Grouse Ridge is primarily a summer and early fall destination. Most years, the snow begins melting from the trailheads in late spring, with the hiking season running until the first significant snowstorms return in the fall.

If your goal is wildflowers, keep an eye on local hiking groups and social media. Early summer often transforms the meadows with colorful blooms, making it one of the most beautiful times to explore the basin.

Late summer brings warm days for swimming, reliable trail conditions and some of the best opportunities for backpacking. Early fall offers cooler temperatures, changing colors and fewer visitors before winter closes the high country once again.

Getting There

Most visitors access Grouse Ridge from the Carr Lake Trailhead via Bowman Lake Road. The drive is part of the adventure, with the final miles following narrow mountain roads that can become rough, dusty and washboarded as the season progresses.

Passenger cars can usually reach the primary trailheads in normal summer conditions, but road conditions vary from year to year. If you plan to explore farther into the Grouse Ridge road system beyond the main access points, additional ground clearance may be helpful. Check current road conditions with Tahoe National Forest before your trip, especially early in the season after snowmelt.

Camping & Permits

Dispersed camping and backpacking opportunities are plentiful throughout the Grouse Ridge basin.

At the time of writing, overnight backpacking does not require a wilderness permit in this area, making it one of the more accessible places to experience a Sierra overnight. Regulations can change, however, so it’s always worth checking with Tahoe National Forest before your trip.

Practice Leave No Trace principles, camp on durable surfaces and respect existing campsites whenever possible.

Fires & Bear Safety

Fire restrictions are common during California summers and can change quickly depending on weather and fire danger. Always verify current restrictions before arriving and be prepared to cook with a camp stove if campfires are prohibited.

While bear canisters are not always required in this area, they’re still one of the best ways to protect both your food and the local wildlife. During my conversation with James and Kelsey, they mentioned they teach new backpackers to use bear canisters even on trips where they aren’t required because the habit prepares people for future adventures throughout the Sierra.

Dogs

Grouse Ridge has long been one of my favorite places to hike with Dakota. The moderate trails, countless lakes and opportunities to cool off make it a wonderful destination for well-behaved dogs.

Keep pets under control, pack out waste whenever possible and remember that wildlife, other hikers and changing weather are all part of sharing the backcountry responsibly.

Before You Go

  • Download maps before leaving home—cell service is limited once you reach the trailheads.
  • Carry more water than you think you’ll need, especially on hot summer afternoons.
  • Afternoon thunderstorms can develop quickly during the summer months, so start early whenever possible.
  • Pack layers. Even after warm days, mountain evenings can cool off surprisingly fast.
  • Leave yourself time to explore. One of Grouse Ridge’s greatest strengths isn’t reaching a particular destination—it’s discovering what lies beyond the next lake.

Following the Guides into Grouse Ridge

One of the reasons Grouse Ridge caught my attention again was listening to James and Kelsey describe how they introduce people to this part of Tahoe National Forest.

Rather than sending beginners deep into the backcountry, they use the basin almost like an outdoor classroom. The moderate trails, connected lakes and flexible route options allow them to build trips around the people they’re guiding instead of forcing everyone onto one itinerary.

For a first visit, I’d probably do exactly what they recommend.

Start at the Carr Lake Trailhead.

Spend your first night near Island Lake.

Wake up without feeling rushed.

Then spend the next day wandering toward Penner Lake or exploring farther into the basin before deciding whether to continue or simply enjoy another afternoon beside the water.

That’s one of the biggest lessons I took away from our conversation.

Grouse Ridge isn’t about reaching one famous destination.

It’s about giving yourself permission to explore.

Once you’re there, you’ll probably begin finding your own favorite lakes.

Island Lake

The most popular introduction to Grouse Ridge and a favorite destination for first-time backpackers.

Penner Lake

Continue a little farther and you’ll find a quieter corner of the basin with excellent camping and fishing opportunities.

Five Lakes Basin

Perfect for hikers who enjoy wandering from lake to lake instead of hiking toward one specific destination.
