Beitostølen Trail Arena — Complete MTB Guide

Beitostølen Trail Arena is one of Norway's most extensive mountain bike networks — over 100 km of marked trails from 900 to 1350 masl, graded from beginner-friendly green to expert-level black. All with Jotunheimen as the backdrop.

What is Beitostølen Trail Arena?

Trail Arena is a network of over 100 km of marked MTB trails at Beitostølen, from 900 to 1350 masl. The trails are graded according to international colour standards (green, blue, red, black) and extend from the centre up towards Bitihorn. Season: June–September. Bike rental and a workshop are available on-site.

The Terrain — What Awaits You?

Trail Arena sits in the transition zone between mountain birch forest and open alpine terrain. That means varied surfaces: wide forest tracks at the bottom, singletrack through birch forest at mid-levels, and technical rocky sections towards the summits.

The elevation profile from the centre (930 masl) to the highest trails towards Bitihorn (1350 masl) gives 400 metres of climbing to work with — enough to build varied trails without becoming overwhelming for beginners.

The Trails — Level by Level

Green Trails — Beginners and Families

The green routes stay around the centre and on wide forest tracks. Low technical demand, consistent surface, and easy to navigate. Perfect for a first MTB ride or children wanting to try off-road.

Recommended route: Beitostølen Centre Beginner MTB — 8 km, 120 hm, easy. A flat loop around the ski centre with short, fun trail sections in between.

Blue Trails — A Little More Speed

Blue trails introduce narrower singletrack, some roots, and short technical sections. You need basic MTB technique: standing on the pedals over rough terrain, braking in a controlled manner on descents, and picking a line through rocky sections.

Recommended route: Beitostølen Ski Stadium MTB Loop — 14 km, 350 hm, intermediate. Farm tracks south of the ski centre with panoramic views towards Jotunheimen.

Red Trails — For Experienced Riders

The technical difficulty increases noticeably here. Longer sections with roots, rock, steep descents, and narrow trails where line choice is decisive. Full suspension is recommended, but a hardtail with good technique works.

Recommended routes:

Beitostølen–Mosetertoppen MTB — 16 km, 520 hm, intermediate-challenging
Beitostølen–Slettefjell MTB — 18 km, 450 hm, intermediate-challenging. Technical singletrack with Valdresflya panorama.

Black Trails — Expert Level

Black trails are only for experienced mountain bikers. Steep boulder fields, drop-offs, technical traverses, and sections where you may need to push. Full suspension is a must.

Recommended routes:

Trail Arena Expert — 22 km, 750 hm, challenging. The advanced variant with technical singletrack, rocky sections, and roots.
Bitihorn MTB — 28 km, 890 hm, challenging. Beitostølen's ultimate challenge — up to 1607 masl with Bygdin and Jotunheimen panorama. Read our Bitihorn MTB complete guide.

Three Day Plans — From Beginner to Expert

Day 1: Beginner (2–3 hours)

Start with the centre beginner loop (8 km, 120 hm). Ride it twice — first at an easy pace to learn the terrain, then with a bit more speed. Lunch in the centre. Afternoon: a short ride on green/blue trails in the ski stadium area.

Total: ~15 km, 250 hm, easy pace.

Day 2: Intermediate (4–5 hours)

Combine the ski stadium MTB loop (14 km, 350 hm) in the morning with Mosetertoppen (16 km, 520 hm) after lunch. Between rides: top up at the bike workshop, adjust tyre pressure.

Total: ~30 km, 870 hm. Bring extra food and water.

Day 3: Expert (5–7 hours)

Start early with Trail Arena Expert (22 km, 750 hm). After lunch and recovery: Slettefjell technical (18 km, 450 hm) or take on the challenge up to Bitihorn if your legs hold.

Total: 40–50 km, 1200–1640 hm. Requires good fitness and full suspension.

Season and Weather — Timing Matters

After rain: Give the trails 12–24 hours to dry. Red and black trails with a rock base dry fastest. Dirt trails in the birch forest need longer. Check yr.no for Beitostølen before you plan.

Wind: Above 1100 masl it can blow hard even on good-weather days. Windproof jacket in the pack — always.

Safety on the Trails

Helmet is mandatory — on green trails too
Glasses protect against branches and insects
Gloves give better grip and protect in a fall
Pump, inner tube, and multitool — always carry them
Mobile coverage is variable above 1100 masl — download offline maps
Never ride black trails alone unless you are very experienced and have shared your location
Emergency numbers: 113 (emergency services), 02222 (Red Cross helpline)

Combine Trail Arena with Other Routes

Trail Arena is perfect as a base, but don't limit yourself to the trails alone. From Beitostølen you can reach:

Valdresflya — 22 km climb to 1389 masl, Norway's most iconic cycling climb. Read our Valdresflya complete guide.
Mjølkevegen — 250 km national cycling route starts/ends here
Panoramavegen — 28 km mountain road with panoramic views
Stølsvidda — gravel through living mountain farm culture

A good week plan: 2–3 days Trail Arena MTB, 1 day Valdresflya road cycling, 1 day Stølsvidda gravel. That gives you the full range of what Beitostølen offers.

Practical Info

From Oslo: Bus via Fagernes, approx. 3.5 hours. Check transport to Valdres for up-to-date departures and bike-on-bus rules.

Technique Tips — Master the Trail Arena Terrain

Trail Arena terrain differs from lowland trails. Here are the techniques that make the difference between flow and frustration.

Roots and Wet Birch Forest

Roots in the birch forest become as slippery as soap after rain. Cross them at a right angle — never diagonally. Keep your weight back over the rear wheel and release the brakes just as you hit the root. Low tyre pressure (1.4–1.6 bar on 2.35" tyres) gives noticeably better grip.

Rocky Sections Above the Tree Line

Above 1100 masl you encounter boulder fields and loose shale. The rules here are:

Steep Climbs (8–15% gradient)

Trail Arena has short, steep ramps where you lose momentum quickly. Shift down BEFORE the ramp — not in the middle of it. Keep your upper body low towards the bars to hold the front wheel down. Pedal in smooth circles, not with power bursts — that spins the rear wheel on gravel.

Descending with Control

A dropper post is your best friend. Lower the saddle 8–10 cm on technical descents. Push your hips back behind the saddle, extend your arms, and brake with both brakes — but never lock the wheels. In corners: brake BEFORE the corner, release through the corner itself.

After the Ride — Recovery and Activities at Beitostølen

A day on Trail Arena calls for good recovery. Beitostølen has a surprisingly wide range to offer once the cycling shoes come off.

Combination tips for an MTB week:

Days 1–2: Trail Arena green/blue trails — getting used to the terrain
Day 3: Rest day — Bitihorn hike or swimming at Øyangen
Days 4–5: Red/black trails and longer routes towards Slettefjell
Day 6: Gravel ride on Stølsvidda — completely different terrain, active recovery for MTB legs
Day 7: Favourite trails again, or Valdresflya on a road bike

Beitostølen works as a base for a full week without getting bored. Combine MTB with gravel, road cycling, and outdoor activities — that is what makes the place special.

Children at Trail Arena — Age Guide 4–16 Years

Trail Arena is one of the better places in Norway to introduce children to mountain biking. Marked trails with clear grading make it easier to choose the right level — and shorter loops mean no one has to ride further than their legs allow.

Progression plan over a week:

Day 1: Pumptrack + 2 km flat gravel track. Let the child set the pace.
Day 2: Green trail loop (4–6 km). Parent in front, child behind.
Day 3: Rest day — swimming at Øyangen, climbing park, or a hike.
Day 4: Green trail loop again, this time the full 8 km. Reward along the way (chocolate at the halfway point).
Day 5: First careful attempt at a blue trail section (500–800 m). Rest on green.

Safety for children: Helmet always. Gloves always. Knee and elbow pads for children under 10 on anything above green trails. Children under 12 never ride without an adult. Maintain eye contact — if the child is 30 metres behind, you are too far ahead.

Rainy Days — Trail Arena in Bad Weather

Some days it pours. That does not mean the bike has to stay put. Trail Arena has trails that work in wet weather — and trails you should avoid.

Rain strategy for Trail Arena:

Light drizzle: Ride as normal, but stick to trails with a rock base or gravel. Blue birch forest trails are slipperier than they look.
Heavy rain (>10 mm): Gravel tracks and green trails. Good training, minimal trail damage. Avoid singletrack — you dig ruts that damage the trail for others.
The day after: Rock-base trails dry in 2–4 hours. Dirt trails need 12–24 hours. Start on red/black with rocky surfaces, then work down to blue as they dry.
Full rain day: Beitostølen centre has a café, grocery store, and bike workshop — perfect for maintenance, tyre changes, or just a lazy day with coffee and cycling videos.

Never ride muddy trails for fun: Wheel ruts in wet soil erode and take weeks to repair. Trail Arena is built on community effort and maintained locally. Show respect — ride gravel when the ground is soft.

Trail Arena is under continuous development — new trails and improvements arrive every year. Check locally on arrival for the latest update on trail conditions.
