Adventures On Land
Biking & Skating
Everyone from road cyclists, trail bikers, and afternoon cruisers will enjoy adventuring through the area on their favorite two-wheeler of choice. Recreational trails offer rugged terrain for beginner to advanced mountain bike riders. Winding country roads provide smooth surfaces for road cyclists, and Alpena’s 18 ½ mile Bi-Path takes pleasure bikers on a tranquil loop throughout the city.
Riverside Skate Park
Skateboarders and rollerbladers can try their skills at this free park. Located on Ninth Ave. east of the bridge, Riverside Skate Park features 15,000 square feet of surface with 14 ramps and elements, including a halfpipe and a Mini Skate Park designed for the beginning skater with ramps 3-4 feet high. Safety equipment is recommended, and skating enthusiasts use at their own risk.
Alpena Bike Park
This new park is for BMX bikes only. The Alpena Bike Park is located at Mich-E-Ke-Wis Park off of State Street. It consists of quarterpipes, a jump box and a grind box. Safety equipment is recommended, and bikers use at their own risk. The park is free and is open from dawn until dusk.
Geocaching is an entertaining adventure game for GPS users. Pronounced geo-cashing, it is the sport of treasure hunting using a Global Positioning Unit instead of a map. There are many caches hidden in the Alpena area and a regional organization meets regularly and hosts events.
The Northern Michigan Geocachers main objective is coming together in order to socialize in a family friendly atmosphere, discuss our activities, plan and execute various larger events, promote the educational benefits associated with geocaching, contribute group volunteerism in our communities, forests and recreational areas, as well as increasing traffic at our caches. Our activities are organized through our regular meetings, in our online c hat, and in our forum.

Mystery Valley Sinkhole
GPS: 45.21225, -83.73243
Mystery Valley is a unit of the Thunder Bay Karst Preserve, along with Stevens Twins Sinks and Bruski Sink. The 76-acre Mystery Valley Karst Preserve and Nature Sanctuary is located in Presque Isle County just a few miles north of the Thunder Bay Karst Preserve. It contains one of the largest karst “collapse valleys” in the Great Lakes region, several dramatic earth cracks and a lake that rises and falls, and sometimes disappears! Visitors to the preserve can follow two self-guided trails: Earthcrack Trail and Valley Trail. Earthcrack Trail passes a series of cracks, including two that converge into one that’s several hundred feet long and nearly 15 feet deep. Following the Valley Trail, visitors can see fossils of marine invertebrates such as brachiopods, bryzoa and crinoids that lived some 350 million to 400 million years ago. Unlike a valley carved by a river, Mystery Valley was formed by the collapse of the surface into a labyrinth of subterranean chambers created by the water erosion of rock below. Mystery Valley is 1.5 miles long, 500 yards wide at its widest point and about 150 deep, making it one of the largest known collapse valleys in the Great Lakes region.
