With more than nine miles of undeveloped shoreline and six lakes, this angler's paradise is one of the last large tracts of undeveloped lakeshore and land in west central Minnesota. In addition to the typical motorized boating and fishing opportunities offered in the park on Molly Stark Lake, Glendalough also offers a designated "Heritage Fishery" on Annie Battle Lake. This 335-acre lake, located near the park campground, was for the most part, a private fishing lake for many years, and its fish populations and sizes are more comparable to historic times than most public fishing lakes. Very large bass and panfish are still relatively abundant, as are walleyes of good eating size. Special experimental regulations are in effect to preserve the serenity of this undeveloped lake and give anglers the opportunity to catch these sizeable fish. As a result, visitors can experience fishing as it was 100 years ago. Check with the park for current fishing restrictions. No gas-powered augers are allowed during winter fishing. During spring and fall migration, to the delight of birdwatchers, the park becomes a major waterfowl staging area. Two observation areas in the park provide excellent opportunities to see wildlife activity. Hiking trails take you through oak and northern hardwood forests. One trail leads to a prairie hill.
