Don’t fall into the trap of con­sid­er­ing the win­ter months to be lazy ones. Just because the tem­per­a­ture has dropped just a bit doesn’t mean the excite­ment has to be frozen over as well. In fact, all across the coun­try there are unique adven­ture oppor­tu­ni­ties all thanks to the win­ter fore­casts. Whether it’s explor­ing cli­mate-con­trolled caves or soak­ing in some hot springs, there’s a long list of engag­ing win­ter adven­ture out­ings; here are a few great places to start.

Locat­ed 100-ft. under­ground in a for­mer lime­stone cav­ern, this new­ly ren­o­vat­ed, amaz­ing under­ground space now hosts over 320,000 square feet of trails, jumps and a nat­u­ral­ly cli­mate con­trolled area for you to bike all win­ter long. Rentals are avail­able, and whether you bor­row one of theirs or bring your own, you’ll find plen­ty dirt to push around down here.

Bre­it­en­bush Hot Springs—Detroit, Oregon

For those that thrive in cold­er con­di­tions, the exten­sive 45 miles of trails that con­nect the dif­fer­ent huts found in the wilder­ness of South­east­ern Maine is the place for you. While the ski­ing is fun, the real adven­ture lies with­in the four dif­fer­ent huts oper­at­ed by Maine Huts & Trail, each equipped with hot water show­ers, heat­ed bunk rooms and all the ameni­ties you need to have a good win­ter time. All the huts oper­at­ed in the area are com­mu­nal, so you can expect to meet some oth­er avid win­ter adven­tur­ers, adding a lit­tle body heat to the win­ter warmth.

Lake Supe­ri­or Ice Caves—Bayfield, Wisconsin
As part of the Apos­tle Islands Nation­al Lakeshore, all along the shore­line of Mawik­we Bay in Wis­con­sin are some amaz­ing win­ter mar­vels wait­ing for you to explore. While it is pos­si­ble to pop into a sea kayak and approach the caves by pad­dling, addi­tion­al road and trail access make these daz­zling ice caves a pop­u­lar spot all win­ter long. Prop­er footwear and win­ter appar­el is strong­ly rec­om­mend­ed, and with these nat­ur­al attrac­tions com­prised entire­ly of rock and ice, it pays to always keep your head on a swiv­el and know that con­di­tions are always chang­ing with­in the Lake Supe­ri­or Ice Caves.

Intro­duc­to­ry Win­ter Moun­taineer­ing Courses
If you thought explor­ing high alpine areas and moun­tains was a task in the sum­mer, add in some freez­ing tem­per­a­tures and heavy accu­mu­la­tions of snow and you have your­self a real adven­ture. It’s not advised to explore moun­tains in the win­ter if you’re inex­pe­ri­enced and alone, but rather to go with a guide before you ven­ture out on your own. Most intro class­es are rel­a­tive­ly affordable.

For a win­ter-ready retreat under­ground, the Lost Sea Cav­ern in Sweet­wa­ter, Ten­nessee has enough for the whole fam­i­ly to explore.

Dai­ly tours will take you into the cav­ern and across the lake on a glass-bot­tomed boat, but for the true adven­ture, it’s worth your while to form a group and take part in the mul­ti-hour Wild Cave Tour, which will get you on your hands and knees to explore all the nooks and cran­nies the guides can get you through.

Whether you take part in the race itself, or watch the oth­er events includ­ing a Junior Birkie and Barkie Birkie Ski­jor com­pe­ti­tion, there’s plen­ty of hot cocoa and good cheer at the Amer­i­can Birke­bein­er to go around.

Set­ting a high bar for win­ter fun and explo­ration, Grand Targhee Resort in Alta, Wyoming was one of the first ski resorts to wel­come fat bikes onto their Nordic trail sys­tems.
