Adventure at the city’s edge
Very few American cities put wilderness this close. From a downtown Burlington hotel you can be riding a lakeshore bike path within five minutes, swimming off a sand beach in fifteen, paddling open water in twenty, standing on a valley overlook in half an hour, or scrambling onto a 4,000-foot alpine summit inside ninety minutes. Nothing here requires an expedition; almost everything can be done between breakfast and dinner.
The geography is what makes it work. Chittenden County occupies the narrow, fertile shelf between Lake Champlain and the spine of the Green Mountains — 120 miles of freshwater on one side, the highest peaks in the state on the other, and the Winooski River cutting through the middle. The result is an unusual concentration: lake sports, river gorges, waterfalls, alpine hiking, world-class gravel and mountain biking, nordic skiing and a downhill area, all inside one small county.
This guide covers it season by season and activity by activity — the great bike path and the causeway, the beaches and swimming holes, paddling routes, the summits worth your legs, the mountain-bike networks, winter options, quiet wildlife corners, and the practical business of renting gear and getting to trailheads.
The Island Line Trail and the Colchester Causeway
The single best outdoor thing to do in Chittenden County is also the easiest. The Island Line Trail runs about fourteen miles from Oakledge Park in Burlington’s South End north along the lakeshore, through Waterfront Park and the city’s beaches, into Colchester — and then does something extraordinary. At Airport Park the trail joins the old Rutland Railroad bed and heads straight out onto Lake Champlain on a three-mile marble causeway, a raised stone berm barely wider than the path itself, with open water on both sides.
The causeway was built in 1899–1901 from hand-laid marble blocks quarried in Vermont, carrying trains from Burlington out to the Champlain Islands and on to Canada until the line closed in the 1960s. Riding it now feels like cycling on the surface of the lake: no railings, no shade, water lapping a few feet below on either side, the Adirondacks ahead to the west and the Green Mountains behind you.
Two-thirds of the way out is the Cut — a 200-foot gap deliberately left open for boat traffic. From roughly mid-June to early October a small bike ferry, run by Local Motion, shuttles cyclists across for a modest fee, and the trail continues to South Hero in the Champlain Islands, making a genuinely epic 30-mile day ride to Allen Point and back. Outside ferry season you simply ride to the Cut, sit on the marble and look at the water, which is arguably just as good.
The whole route is flat, car-free for most of its length and suitable for any fitness level; children ride it happily. Rent from a waterfront shop, bring water and sunscreen — there is no shade whatsoever on the causeway — and check the ferry schedule and wind forecast, because a strong westerly out on the berm is no joke.
Beaches, swimming and the waterfront parks
Lake Champlain is warm enough for comfortable swimming from late June through early September, and Burlington has a genuine string of city beaches.
North Beach, a short ride north of downtown, is the biggest — a broad sand crescent with a campground, snack bar, kayak and paddleboard rentals and warm shallow water, best for families. Leddy Park, a little further north, has a quieter beach, a big lawn, tennis courts and an ice arena. Oakledge Park at the trail’s southern end offers rocky ledges to jump from, a small beach, a lakeside picnic area and Vermont’s first fully accessible treehouse overlooking the water. Waterfront Park itself is for sitting rather than swimming — lawns, the famous swinging benches, boat cruises and the ECHO science center.
Beyond the city, Shelburne Bay Park and Red Rocks Park in South Burlington give wooded clifftop paths above the water with swimming coves below; Sand Bar State Park, half an hour north on the causeway road toward the islands, has the warmest, shallowest swimming in the region. For freshwater away from the lake, Bolton Potholes on Joiner Brook is a famous chain of deep rock pools east of Richmond — beautiful, extremely popular, and genuinely dangerous in high water.
One serious warning. Huntington Gorge, a narrow slot canyon on the Huntington River, is the most lethal swimming hole in Vermont; more than twenty people have drowned there. Its currents and undercut rock are unforgiving. Local advice is unambiguous: look, do not swim.
Paddling, sailing and being on the water
Lake Champlain is 120 miles long and up to 400 feet deep, which makes it a proper inland sea — it can turn from glass to whitecaps in twenty minutes, so watch the forecast and stay close to shore in a kayak or on a paddleboard.
The gentlest paddling is in the sheltered bays: Shelburne Bay south of the city, the Winooski River delta, Malletts Bay in Colchester, and the marshes of the LaPlatte River Natural Area, where you slip between cattails watching herons and osprey. Colchester Pond and Indian Brook Reservoir are quiet, motor-free, and lovely at dawn.
For bigger ambitions, the Lake Champlain Paddlers' Trail links primitive campsites down the length of the lake for multi-day trips. Rentals and lessons are easy to arrange on the Burlington waterfront, where you will also find sailing schools, charters, the Community Sailing Center’s programs and the Spirit of Ethan Allen’s narrated cruises. Fishing is excellent — lake trout, salmon, bass and legendary spring perch runs — with guides operating out of Burlington and Malletts Bay.
And keep an eye out for Champ, the lake’s resident monster. Sightings date to the 19th century, the Vermont legislature has passed resolutions protecting it, and every lakeside bar has an opinion.
Summits within an hour
The county and its immediate edges hold a full ladder of climbs, from stroller-friendly to genuinely alpine.
Mount Philo, Charlotte — 968 ft; a 0.8-mile walk or a short paved road to the best easy view in Vermont, over the Champlain Valley and the Adirondacks. Superb at sunset and for September hawk migration.
Camel’s Hump, Duxbury/Huntington — 4,083 ft; Vermont’s wildest big summit, 5–7 miles round trip with alpine tundra on top. No road, no lift, no buildings.
Mount Mansfield, Underhill — 4,393 ft; the state’s highest, via Sunset Ridge from Underhill State Park for an open alpine ridge, or the toll road and gondola from Stowe.
Bolton Valley & Bolton Notch — resort trails, Preston Pond, and ledges above the notch; a good rainy-day-alternative network.
Snake Mountain, Addison — a gentle, quieter climb to a broad valley overlook 40 minutes south.
Hinesburg & Williston town forests — easy, well-signed local loops for a short day or a run.
Red Rocks & Ethan Allen Homestead — flat wooded and riverside walking inside the city limits.
Mountain biking and gravel
Chittenden County is a strong riding area in its own right, and it sits an hour from the best network in the eastern United States.
Locally, Sleepy Hollow Inn in Huntington runs a well-built network of singletrack and doubletrack on a working property that turns nordic in winter. Perry Hill in Waterbury, twenty-five minutes east, is the area’s technical classic — steep, rooty, rocky descents that reward good bike handling. Bolton Valley has lift-served and cross-country trails; Cochran’s Ski Area in Richmond and the Williston and Hinesburg town forests offer mellower riding; and Burlington’s own Centennial Woods and Ethan Allen Homestead give short after-work loops.
Gravel riding may be the county’s real secret. The dirt-road network through Huntington, Hinesburg, Charlotte and Richmond is endless, quiet and beautiful — rolling farm roads with mountain views and almost no traffic. Local shops can point you at loops, and Vermont’s gravel events draw riders from across the country.
For a day trip, Kingdom Trails in East Burke, about ninety minutes northeast, has more than 100 miles of singletrack across privately shared land and is regularly voted the best network in the East. It is worth the drive and then some.
Winter outdoors
The county does not shut down in winter; it changes gear.
Bolton Valley, 40 minutes east, is the closest downhill area to Burlington — a family-scale resort with a strong backcountry and uphill-skiing culture, night skiing and a nordic center high on the mountain. Stowe and Smugglers' Notch, both under an hour, provide the big-mountain days; Cochran’s in Richmond is a tiny, historic, volunteer-run hill and one of the friendliest places to teach a child to ski.
For nordic skiing, Sleepy Hollow in Huntington and the Catamount Outdoor Family Center in Williston groom excellent trail networks close to the city, and the Bolton Valley nordic center adds high-elevation snow that lasts. Snowshoers can use almost any of the summer trails — Mount Philo, Red Rocks, Centennial Woods and the town forests are all straightforward — and the frozen lake margins, Colchester Pond and Malletts Bay draw skaters, ice fishers and, in a hard winter, Nordic skaters chasing black ice.
The Island Line Trail stays walkable and fat-bikeable, and the causeway in winter, with the lake frozen and empty on both sides, is one of the strangest and most beautiful walks in Vermont — but only with local knowledge of the ice.
Quiet corners and wildlife
Not every outing needs a summit. The Ethan Allen Homestead, minutes from downtown, preserves Vermont’s founding folk hero’s 1787 farmhouse alongside flat trails through the Winooski River delta — excellent birding, especially in spring migration. Adjacent Delta Park protects a sandy river mouth on the lake.
The LaPlatte River Marsh Natural Area in Shelburne and Shelburne Bay’s wooded shoreline are good for herons, osprey and quiet paddling. Colchester Pond and Indian Brook Reservoir offer motor-free water and easy loop trails. Centennial Woods, a 70-acre pocket of forest owned by the university inside the city, is a genuine escape ten minutes from Church Street.
Half an hour north, the Missisquoi National Wildlife Refuge in Swanton protects one of the great river deltas of the Northeast, with thousands of migrating waterfowl in spring and fall. Closer to home, keep an eye out for the county’s ordinary wildlife spectacle: osprey nesting on lake pilings, bald eagles recovering along the Winooski, spring peepers deafening in April wetlands and, on quiet dirt roads at dusk, moose in the higher towns.
Gear, rentals and logistics
Everything here is easy to organize once you know where to go.
Bike rental — waterfront shops in Burlington rent hybrids, e-bikes, kids' bikes and trailers by the hour or day, right on the Island Line Trail.
Bike ferry — runs roughly mid-June to early October across the causeway Cut; small fee, cash or card, check the daily schedule and wind.
Paddle rental — kayaks and paddleboards at North Beach, the waterfront and Shelburne Bay; sailing lessons and charters at the Community Sailing Center.
State park fees — modest day-use charges at Mount Philo, Sand Bar and Underhill; cash or card at the gate, cheaper on foot.
Trailhead parking — Camel’s Hump and Mount Philo fill before 9am on summer and foliage weekends; go early or midweek.
Mud season — stay off high-elevation trails from mid-April to Memorial Day while the tread thaws.
Weather — summit temperatures run 20°F colder than the valley with strong wind; the lake changes fast. Check both forecasts.
No shade — the causeway and open ridges have none; carry water, sunscreen and a windproof layer year-round.
Where to stay
Burlington and the waterfront are the obvious base for anything lake-related: downtown hotels put you on the Island Line Trail and within walking distance of rentals, beaches and dinner, and no car is needed for a bike-and-swim weekend.
South Burlington and Colchester sit closer to the causeway, Malletts Bay and the airport, with easy parking and good value. Shelburne and Charlotte are minutes from Mount Philo, Shelburne Bay and the southern beaches, with country inns and B&Bs.
For mountains, Richmond, Huntington and Waterbury put the Camel’s Hump trailheads, Perry Hill and Bolton Valley within twenty minutes, and Stowe and Underhill are the right choice for Mount Mansfield. Winter visitors often split the difference — a Burlington base for food and city life, or Bolton and Stowe for ski-in convenience.

Good to know
What is the Colchester Causeway?+
A three-mile marble railway berm built in 1899–1901 that carries the Island Line bike path straight out onto Lake Champlain, with open water on both sides. Two-thirds of the way out, a gap called the Cut is crossed by a seasonal bike ferry (roughly mid-June to early October), letting riders continue to the Champlain Islands.
Where can I swim near Burlington?+
North Beach and Leddy Park north of downtown, Oakledge Park to the south, Red Rocks and Shelburne Bay in South Burlington and Shelburne, and Sand Bar State Park half an hour north for the warmest shallow water. Bolton Potholes near Richmond is a popular rock-pool swimming hole; avoid Huntington Gorge entirely — it is Vermont’s most dangerous.
How close are the mountains?+
Very close. Mount Philo is 25 minutes south, the Camel’s Hump trailheads 35–40 minutes east, Bolton Valley 40 minutes, and Mount Mansfield and Stowe under an hour. You can hike a 4,000-foot summit and be back in the city for dinner.
Can I do all this without a car?+
Mostly, in summer. The Island Line Trail, city beaches, waterfront rentals, paddling and Centennial Woods are all walkable or bikeable from downtown Burlington. Mountain trailheads and the ski areas need a car, a rideshare or a shuttle.
What is there to do outdoors in winter?+
Downhill skiing at Bolton Valley, Stowe, Smugglers' Notch and tiny Cochran’s; nordic skiing at Sleepy Hollow, Catamount and Bolton; snowshoeing on almost any summer trail; skating and ice fishing on Colchester Pond and Malletts Bay; and fat biking or walking the Island Line Trail along the frozen lake.
