While the Giant's Causeway and Causeway Coast dominate Northern Ireland tourism, walkers know something different. The Nine Glens of Antrim offer what driving routes cannot deliver: intimacy with glaciated valleys, the sound of waterfalls hidden in mountain folds, the sense of genuine wilderness within reach of the coast. This guide focuses on walking these glens—not as a scenic drive observation but as a hiker fully inhabiting these dramatic landscapes.

The Nine Glens of Antrim represent something special in Irish walking: genuine remoteness combined with excellent accessibility. These glaciated valleys tumble from Antrim's high moorlands toward the Irish Sea, creating landscapes of extraordinary drama and beauty. Walking the Glens of Antrim reveals what cars miss entirely—the scale of waterfalls, the detail of stone-walled paths, the sense that you're exploring landscapes few tourists ever truly experience.

This isn't exaggeration. The Causeway Coast drive presents these valleys as scenic postcard views. Walking them reveals geology, ecology, and scale that photographs cannot capture. You develop understanding—the power of water that carved these valleys, the effort of farmers who carved paths through seemingly impossible terrain, the spiritual appeal that drew people to settle in these remote places.

The Nine Glens: Location and Overview

The Nine Glens stretch along the North Antrim coast, roughly between Larne (south) and Ballycastle (north). From south to north, they are: Glenlough, Glenarm, Glenshesk, Glenballyeamon, Glenwhirr, Glendun, Glentaisie, Glencoy, and Glenariff. Not all are equally developed for walking, but each offers distinct character and specific trail opportunities.

The region sits approximately 1.5 hours from Belfast, making it accessible for a dedicated hiking weekend or several days of focused glen exploration. Accommodation in the region has improved markedly in recent years—Northern Irish walking infrastructure has accelerated, with improved trail markings and walker-friendly guesthouses becoming increasingly common.

Glenariff Glen: The Queen of the Glens

Why Glenariff Dominates Glen Walking

Glenariff, the largest and most developed glen, has earned its reputation as "the Queen of the Glens." This isn't just marketing—Glenariff combines exceptional scenery with well-maintained trails and genuine facilities. The glen extends approximately 15 km inland, widening progressively as it descends from the moorlands.

What makes Glenariff distinctive is the combination of waterfall scenery (particularly Rainbow Falls and Ess-na-Crubh waterfall), forest trails (the Glenariff Forest Park), and multiple trail options suited to varying fitness levels.

Main Walking Routes in Glenariff

Glenariff Forest Park Loop (8-9 km, 2.5-3 hours)

The most developed walk in the glen, this trail navigates the lower valley where the river has carved spectacularly through the landscape. The route passes Rainbow Falls (where summer light creates actual rainbows in the spray), woodland sections, and valley viewpoints.

Difficulty: Moderate. The trail is well-marked and established. Elevation change is significant but manageable for any reasonably fit hiker. Water crossings can be challenging after heavy rain but are generally straightforward.

Why walk it: This is accessible Glen walking that delivers genuine dramatic scenery. The waterfall photography is exceptional in certain light. The sense of being within a wild valley is complete.

Ess-na-Crubh Waterfall Walk (6-7 km, 2-2.5 hours)

This route explores the upper glen valley, featuring Ireland's longest unbroken waterfall cascade, Ess-na-Crubh. The walk combines moorland approaches, forest sections, and waterfall drama.

Difficulty: Moderate to Challenging. Elevation is more substantial than the lower loop. The trail becomes rougher toward the waterfall. Some scrambling required in final approaches.

Why walk it: If you want to feel genuinely remote while accessing a truly dramatic waterfall, this delivers. The moorland sections offer expansive views. The waterfall itself is worth the effort.

Glenariff River Walk (5 km, 1.5-2 hours)

A gentler option following the river through lower glen sections, suitable for varying fitness levels. The walk offers waterfall views, river scenery, and woodland immersion without significant elevation.

Difficulty: Easy to Moderate. Well-established trail, minimal elevation gain. Suitable for families and those seeking gentle walking.

Why walk it: When weather turns poor or energy levels are lower, this delivers glen experience without excessive challenge. It's an excellent warm-up walk before tackling more demanding routes.

Accommodation and Logistics

Glenariff sits near Waterfoot, a small coastal village offering guesthouses and basic services. Walking tour operators increasingly feature Glenariff walking, with luggage transfer making multi-day glen exploration possible. You can spend 2-3 days based in Waterfoot, exploring different Glenariff routes at your own pace.

Glenarm Glen: The Accessible Alternative

Character and Appeal

Glenarm, the southernmost glen, often receives less attention than Glenariff but offers distinct appeal. The glen combines coastal access (Glenarm village sits on the coast), forested river sections, and less crowding than its famous neighbor.

Glenarm suits walkers seeking genuine glen atmosphere without the Glenariff bustle. The accommodation infrastructure is developing well—small guesthouses increasingly welcome walkers specifically.

Main Walking Route

Glenarm Forest Trail (6-8 km, 2-3 hours)

A forest walk following Glenarm River through lower and middle glen sections. The trail passes through mature forest, alongside river, and offers waterfall access. Multiple route variations allow you to customize distance and difficulty.

Difficulty: Easy to Moderate. Forest trails are well-maintained. River crossings are generally straightforward. Elevation is less aggressive than Glenariff.

Why walk it: This is genuine glen walking in a quieter setting. Walkers report feeling they've discovered somewhere authentic and less-touristed. The forest is beautiful, and the sense of being in a hidden valley is pronounced.

Upper Glenarm Ramble (5-6 km, 1.5-2 hours)

Explores the upper glen valley with moorland sections and viewpoints. Less developed than lower trail but follows clear paths. Offers expanding views as elevation increases.

Difficulty: Moderate. More rugged than forest trail but still manageable. Elevation change is noticeable.

Why walk it: For walkers wanting to feel they've ventured into genuine remote territory while maintaining clear trail access.

Glencoy Glen: The Hidden Gem

Character and Surprise Factor

Glencoy remains genuinely off most walking tourists' radar, which is exactly why experienced walkers are discovering it. The glen offers exceptional scenery—dramatic cliffs, waterfalls, river walks—without the crowds of its famous neighbors.

Accommodation is more limited here than Glenariff or Glenarm, but that's part of the appeal. This is authentic glen walking without tourist infrastructure overwhelming the experience.

Main Walking Route

Glencoy Glen Trail (7-8 km, 2.5-3 hours)

Following the river from coastal approaches inland, this walk passes waterfalls, waterside sections, and expanding valley views. The trail becomes progressively more remote as you venture further into the glen.

Difficulty: Moderate. Well-defined path but more rugged than formal forest trails. River crossings straightforward in dry conditions but can be challenging after heavy rain. Elevation change is moderate.

Why walk it: This delivers authentic Glen walking experience. You're likely to encounter few other walkers. The scenery is exceptional without being famous. The sense of discovery is strong.

Glendun Glen: The Long Valley

Character and Scope

Glendun, the longest of the glens, extends remarkably far inland—approximately 17 km from coast to moorland. This length means multiple trail options at different distances and difficulty levels.

The glen's length also means you can venture well into genuinely remote territory while maintaining clear return routes. Walking the full glen requires commitment and proper planning, but the reward is feeling like you've truly explored a substantial landscape.

Main Walking Routes

Lower Glendun Valley Walk (5-6 km, 1.5-2 hours)

Explores the glen's coastal approach and lower valley sections. Well-marked trail, manageable elevation, suitable for walkers of varying abilities.

Difficulty: Easy to Moderate. Clear trail, minimal exposure, straightforward navigation.

Why walk it: Access to glen atmosphere for walkers with limited time or fitness limitations.

Mid-Glen Exploration (8-10 km, 3-4 hours)

Ventures deeper into the glen, passing through forest sections, river valleys, and expanding moorland views. Requires decent fitness and navigation confidence.

Difficulty: Moderate to Challenging. Trail becomes less developed the further you venture. Route-finding requires attention. Elevation is more substantial.

Why walk it: For walkers wanting a full day immersed in glen scenery, with genuine sense of venture and discovery.

Planning Multi-Glen Walking Tours

The Antrim Glens and Causeway Coast Tour Opportunity

Our Antrim Glens and Causeway Coast walking tour combines multiple glens with coastal walking, creating a comprehensive Northern Irish walking experience. Luggage transfer throughout means you walk at your own pace, exploring different glens from comfortable accommodation.

Recommended Pacing

A 5-day glen focus might look like:

  • Day 1: Arrive, gentle Glenarm Forest walk, settle in
  • Day 2: Full Glenariff Glen day (morning Ess-na-Crubh, afternoon Rainbow Falls)
  • Day 3: Rest day or lighter walk; explore coastal sections
  • Day 4: Glencoy Glen or Glendun lower glen
  • Day 5: Final glen experience or return toward coast

This allows full immersion in different glens without excessive daily distance.

A 7-day tour adds Glendun full exploration, rest days, and additional glen time.

Walking Versus Driving: What Cars Miss

Here's what needs emphasizing: the Causeway Coast drive presents the Nine Glens as scenic postcard views. The real magic happens when you abandon the car and actually walk these valleys.

Cars show you the glens. Walking reveals them:

  • Scale: Photographs and car windows make waterfalls look pleasant. Walking beneath a 50-meter cascade with spray hitting your face communicates scale photographs cannot capture. Standing within a valley surrounded by 300-meter cliffs communicates drama that car views miss entirely.
  • Sound: The roar of rivers in flood, the hiss of waterfalls, the wind across moorlands—these auditory experiences are invisible to driving tourists. They're profound and moving when actually experienced.
  • Texture: Stone paths worn smooth by generations of feet, the feel of spray from waterfalls, the resistance of rough moorland grass underfoot—these tactile experiences create memories that driving tourism cannot access.
  • Solitude: You can see glens beautifully from a car. You can truly experience them only on foot, alone or with fellow walkers, at your own pace.
  • Time: Driving the Causeway Coast route takes 2-3 hours. Walking even a single glen thoroughly takes a full day. That extended time allows landscape integration that brief car views cannot achieve.

Practical Hiking Information

Best Times to Walk

May-September: Optimal conditions. Weather generally stable, daylight hours generous, accommodations available. June-August see most foot traffic; May and September offer similar conditions with fewer walkers.

October-April: Possible but demanding. Weather becomes unpredictable. Waterfalls are more impressive (higher water flow), but trails can be muddy and potentially dangerous. Winter walking in glens requires experience and appropriate equipment.

What to Pack

  • Waterproof jackets (essential—weather changes rapidly)
  • Proper hiking boots (not trainers—rocky terrain demands ankle support)
  • Layers (starting warm often means stripping layers within an hour)
  • Hat and gloves (wind on moorlands is chilling regardless of temperature)
  • Water and snacks
  • Map and compass (even well-marked trails benefit from backup navigation)

Trail Difficulty Assessment

Antrim Glen walking is generally easier than southern Irish mountain trails (like Kerry Way or Wicklow high ridges) but more challenging than easy walks. The key difficulty factor is weather rather than technical challenge. Sudden rain, poor visibility, and wind change conditions rapidly.

Navigation

Most developed routes (Glenariff, Glenarm) are well-marked and difficult to lose. Upper glen routes become less formal. Navigation apps (like AllTrails) work well but have limited coverage in remote sections. Traditional maps (OS 1:50,000) are reliable and worthwhile backup.

Accommodation and Services

Guesthouses and Lodging

Northern Irish walking accommodation has improved dramatically. Waterfoot (near Glenariff), Glenarm, and Ballycastle offer handpicked guesthouses increasingly welcoming to walkers specifically. Properties feature early breakfasts, packed lunches, and proprietor recommendations for local routes.

Restaurants and Pubs

Villages offer traditional Irish pub meals—reliable, hearty, warming after a day's hiking. Vegetarian options are increasingly available. Quality is consistently good. Pubs serve as social spaces where conversations with locals enhance understanding of glen history and current walking culture.

Supplies and Services

Most villages have small shops sufficient for trail snacks and supplies. Larger towns (Larne, Ballycastle) offer supermarkets for stocking up before multi-day glen ventures.

The Unique Appeal of Antrim Glen Walking

Walking the Nine Glens offers something distinctive in Irish walking. You experience genuine mountain scenery without the South's famous crowd pressure. You discover landscape that feels less touristed despite being equally spectacular. You encounter walkers who've deliberately chosen less-famous trails, creating a community of genuine walking enthusiasts rather than tourist-focused experiences.

The glens demand proper walking skills and appropriate equipment—they're not gentle strolls, and weather can turn serious. But that challenge is exactly why walkers find them so rewarding. You're not just seeing a scenic postcard. You're genuinely adventuring through terrain that reveals itself properly only when you're on foot.
