🏆 Twin Lakes State Park — A 175-acre park on the shore of Lake Roland in Houghton County, Michigan’s Copper Country — with a 62-site electric campground, a 500-foot swimming beach on one of the warmest inland lakes in the Upper Peninsula, a boat launch, and a 1.5-mile nature trail with two overlooks toward Lake Superior. Not to be confused with Twin Lakes State Park in Prince Edward County, Virginia — a different park in a different state.
Twin Lakes State Park exists for one reason that matters more than any other in this corner of Michigan: the water is warm enough to swim in. The Keweenaw Peninsula is ringed by Lake Superior, which stays punishing well into August. Lake Roland and neighbouring Lake Gerald are two of the warmest inland lakes in the Upper Peninsula — shallow, sheltered, and genuinely comfortable on a July afternoon. The park sits on M-26 halfway between Houghton and Mass City, 175 acres of second-growth forest sloping down to a sand beach, with a campground close enough to the water that you can hear it from your site.
⚠️ Reopening after a full-season closure. The entire park — campground, day-use area and boating access site — was closed through July 2026 for a roughly $1.9 million infrastructure project funded through the Building Michigan Together Plan: a new toilet and shower building, an upgraded sewer system, and a repaved entrance. The Michigan DNR set August 1, 2026 as the anticipated reopening date. Because that timeline was already extended once, confirm the park is open and check reservation availability before you drive up. Status as of August 2026.

Recreation Passport
Every vehicle entering a Michigan state park needs a Recreation Passport. Michigan-registered vehicles pay $14 for a year (or $28 for two years) when added to a licence plate renewal — a $1 increase that took effect January 1, 2026. Buying it later at a park, DNR customer service centre or Secretary of State office adds a $5 convenience fee. Out-of-state vehicles buy an annual or daily non-resident passport instead; check current rates on the DNR Recreation Passport page. Rates as of August 2026.
Planning Notes
This is the swimming park, not the scenery park. If you want Lake Superior cliffs and waterfalls, the Porcupine Mountains and the Keweenaw tip deliver more. What Twin Lakes gives you is water you will actually get into — and for families travelling the U.P. with children, that is often the deciding factor.
Use it as a Copper Country base. From here, Houghton and Hancock are under 40 minutes for supplies and the Quincy Mine, and the drive north up the Keweenaw is a straightforward day trip. The campground is quieter and easier to book than the parks directly on Superior.
Come prepared for a short season. The campground runs May to October, and the shoulder weeks are cold at night this far north. Peak swimming is a narrow window — mid-July into late August is when Lake Roland is at its warmest.
Frequently Asked Questions
Is Twin Lakes State Park open in 2026?
The park was closed through July 2026 for a major infrastructure project — a new toilet and shower building, an upgraded sewer system and a repaved entrance — with an anticipated reopening of August 1, 2026. That date had already been pushed back once, so verify on the official DNR park page before travelling.
Is this the Twin Lakes State Park in Virginia?
No. Virginia also has a Twin Lakes State Park, in Prince Edward County, with a significant African American heritage history from the segregation era. This page covers the Michigan park in Houghton County, on Lake Roland in the Upper Peninsula. The two share nothing but a name.
How warm does the water actually get?
Lake Roland and Lake Gerald are described by the Michigan DNR as two of the warmest inland lakes in the Upper Peninsula. They are shallow and sheltered, so they warm far faster than Lake Superior — which is the practical reason families choose this park over the Superior shoreline. Mid-July through August is the comfortable window.
Are there cabins?
One rustic mini-cabin sleeping four, in addition to the 62 modern campsites. It is a single unit, so it books out well ahead for summer weekends.
Can you see Lake Superior from the park?
Not from the campground or beach, but the 1.5-mile nature trail climbs to two overlooks that open north toward Lake Superior. It is a short, manageable walk and the best viewpoint the park offers.
Keep exploring: F.J. McLain State Park sits on the Lake Superior shore north of Hancock, and Baraga State Park covers Keweenaw Bay to the south. For the whole region, browse all Michigan state parks or use our Park Finder to search by activity, location, or features.
