Sudbury.
Sudbury is a Canadian Shield city built on top of a 1.85-billion-year-old meteorite impact crater — the second-largest confirmed impact structure on Earth, originally an estimated 200–260 km in diameter and eroded to the ~60 × 30 km Sudbury Basin we walk on today. The amalgamated City of Greater Sudbury covers roughly 3,200 km² (the largest city by area in Ontario) and contains roughly 330 lakes within its boundary, including Lake Wanapitei (~132 km², among the largest lakes contained within the boundary of a single city in the world) and Ramsey Lake in the urban core.
Science North on the north shore of Ramsey Lake is Ontario's second-largest science centre; Dynamic Earth at the Big Nickel runs the Going Underground mine descent that interprets 140+ years of nickel mining and the impact-crater geology beneath the city. Sudbury sits within Robinson-Huron Treaty (1850) territory on the traditional lands of the Atikameksheng Anishnawbek and Wahnapitae First Nation.
The regreening program — liming, seeding, and tree-planting on ~3,400 ha of former smelter barrens — earned a UN Local Government Honours Award in 1992 and is the reason the boreal mosaic now stands where the moonscape used to.

worth your time
StrongHiking
Lake Laurentian Conservation Area covers ~2,400 ha on the city's south side with about 30 km of multi-use trails — varied difficulty, four-season, with a visitor centre. Kivi Park spreads ~480 ha and 55 km of trails across Long Lake's south arm, the city's biggest single trail venue. A.Y. Jackson Lookout / Onaping Falls — named after the Group of Seven painter who painted the falls — runs short trails to lookout platforms above the ~35 m High Falls drop on the Onaping River, ~50 km northwest of downtown. Bell Park's lakeside boardwalk and Junction Creek Waterway Park keep walkable trail in the urban core.

StrongMountain Biking
Kivi Park is the Sudbury mountain-biking anchor — 55 km of multi-use trails on 480 ha at Long Lake, purpose-built singletrack maintained in partnership with the Sudbury Mountain Bike Association. Lake Laurentian Conservation Area carries additional multi-use riding on the city's south side. The Canadian Shield terrain — exposed bedrock, jack pine and birch, kettle lakes — is the same surface Sudbury skiers and snowshoers use in winter; the trail network reads year-round.

StrongPaddling — Flatwater
Roughly 330 lakes sit inside the City of Greater Sudbury boundary. Lake Wanapitei (~132 km², 60+ m max depth) is among the largest lakes contained within the boundary of a single city in the world — cold, oligotrophic, with paddle-camping along the north shore and islands. Ramsey Lake in the urban core launches sheltered canoes, kayaks, and SUPs from Bell Park and the Science North area. Long Lake at Kivi Park and Vermilion River sections within the city add further flatwater.

StrongCross-Country & Nordic
The Walden Cross-Country Fitness Club at Kivi Park runs track-set classic and skate trails on a national-club-grade network, with hosting history for provincial and national racing. Lake Laurentian Conservation Area carries additional groomed cross-country trails. Sudbury's reliable mid-December through mid-March snow cover and Canadian Shield rolls give the network consistent conditions across the season.

StrongSnow Adventure
Sudbury Trail Plan Association manages roughly 600 km of OFSC-prescribed snowmobile trails across the Sudbury district — one of Northern Ontario's best-developed sled networks, anchored on the city. Lake Laurentian Conservation Area and Kivi Park carry snowshoe routes on the same trails used for hiking and skiing. Outdoor skating runs at Bell Park's Adanac-area rinks and at municipal community rinks across the amalgamated city.

StrongWildlife Viewing
Sudbury sits on the boreal-southern-edge mix where moose, black bear, beaver, and otter are reliably present across the conservation areas and the regreened landscape. Bald eagles have returned and now nest around Lake Wanapitei and along the Vermilion River corridor. Lake Laurentian Conservation Area, Onaping Falls / A.Y. Jackson Lookout, and the Lake Wanapitei shoreline are the canonical viewing platforms. Sudbury's regreening story is itself a wildlife story — the boreal mix recovering on former barrens carries the species back into corridors that a generation ago carried far less.

▲ SignatureHeritage & Culture
Science North sits on the north shore of Ramsey Lake — Ontario's second-largest science centre, opened in 1984, four floors of exhibits and an IMAX dome inside two snowflake-shaped buildings on the lake. Dynamic Earth, Science North's earth-science campus at the Big Nickel site, runs the "Going Underground" tour that descends roughly seven storeys into a former Inco demonstration drift to interpret the 140+ years of nickel mining beneath the city. The Big Nickel itself — a 9 m / 30 ft replica of the 1951 Canadian nickel — has stood at the Dynamic Earth site since 1964. Anderson Farm Museum (Conservation Sudbury, Lively) and the Copper Cliff Museum carry community heritage on the west side of the amalgamated city.

▲ SignatureGeology & Discovery
The Sudbury Basin is the second-largest confirmed meteorite impact structure on Earth — a ~1.85-billion-year-old crater originally an estimated 200–260 km in diameter, eroded today to a ~60 × 30 km elliptical basin whose rim runs through the city. Dynamic Earth's "Going Underground" tour is the canonical interpretive descent, and the surface geology — the Sudbury Igneous Complex, footwall breccias, Onaping Formation, and shatter-cone outcrops — is interpreted both at Dynamic Earth and on outdoor signage around the basin rim. The Big Nickel adds a 9 m surface anchor, and the regreening program's restoration of ~3,400 ha of smelter-era barrens (UN Local Government Honours Award, 1992) is itself a living geology-and-ecology exhibit.
