Make sure you stop at Miners Castle, Whitefish Point, Tahqaumenon Falls (upper and lower),Top of the World Snowmobile Museum in Naubinway, and Big Spring in Manistique. All are worth the time.
Places where we have stayed and enjoyed. Buckhorn Bar and Cherrywood both are in Munising. Tahquamenon Suites Paradise MI(it is a little more than the hotel, but the beds are fabulous, my husband has back problems and can't handle a bad mattress.). The casino in Sault Saint Marie has great rooms and food options till 2 am in the morning. It is on the more costly side for rooms. The Quality Inn in Newberry good rooms and a full hot complimentary breakfast till 9 am. The Gray Wolf in Manistique plain rooms at a good price.
If weather has been warm before your trip you will want to watch out for the conditions on Southern side of UP. Fire roads going down to St Ignace if the club posts they are icy with little snow they are telling you the truth! You will need scratches or you will overheat.
Trail 2 between Manistique and Newberry has been closed many years lately because Bear Creek Swamp won't stay froze over. This section of trail has been closed many years in a row even in February so if the gates are closed the Swamp is open.
Between Munising and Paradise make sure you eat by 9 pm. The Brewery in Grand Marais, Pine Stump, RedWolf Inn, The Tahqaumenon Brewery at the Falls, and the Inn at Paradise all stop serving food at 9 pm. Some of them won't take an order after 8:30. All serve great food, all are very snowmobiler friendly. Pine Stump has fuel till 9 pm and I have counted 300 sleds there at a time on a Saturday.
Paradise and Newberry area are often spots for DNR traps on weekends. Especially Paradise make sure every member of your party stops at stop signs. PAY ATTENTION TO FLAGS AND ROPED OFF AREAS. People in the community are trying to keep snowmobilers off their septic systems and it has caused a lot of complaints and hard feelings.
There is a Swamp south of Paradise on trail 8. If the gates are closed you will need to ride the shoulder of the road about 2 miles to reconnect with trail at the mouth of the Tahqaumenon River. This is allowed.
Just to warn you the trail connection on 8 between Munising and Grand Marais can get ugly on the weekends. Just to many sleds. I will say the group that took over grooming after 2012 have done amazing improvements since. Used to be groomed by a company and groomers would sit on the weekend. The new club has turned things massively around. Shows what happens when volunteers are involved. Thank you to all of those everywhere that help us enjoy this sport.
Enjoy your trip.
