Mesa de los Tres Reyes is the highest peak in Navarre at 2,444 metres, located in the Pyrenean massif of the Roncal Valley at the region's eastern edge. Its name — Table of the Three Kings — refers to the historic meeting point where the boundaries of the medieval kingdoms of Navarre, Aragon, and France once converged. The standard summit route is an 18-kilometre return trek beginning at the Refugio de Belagua, a staffed mountain refuge at approximately 1,400 metres elevation. The trailhead lies roughly 125 kilometres from Pamplona via the A-21 motorway east and then the NA-137 road south through the Roncal Valley to Isaba, continuing a further 10 kilometres on a narrow mountain road to the refuge. No public transport serves this destination; private vehicle access is essential. From the Belagua refuge, the route climbs steadily northeast through subalpine meadows and dwarf shrub on a well-marked path. The first 5 kilometres gain approximately 600 metres on clear track through open terrain with expanding views into France. Above 2,000 metres the path crosses rocky limestone and scree requiring careful foot placement. The summit block involves short sections of Class 2 scrambling over loose rock. The total ascent of 1,044 metres typically takes 4–5 hours; the descent 3–4 hours. The summit plateau is broad and relatively flat, affording 360-degree panoramas across the Navarro-Aragonese Pyrenees, the French Basque mountains, and on very clear days the Atlantic horizon. A stone border marker (mojón) at the summit marks the historic three-kingdom convergence; a wooden cross marks the highest point. No technical equipment is required in summer for the standard route, but mountaineering boots with ankle support are essential, trekking poles recommended, and a helmet advisable given rockfall risk on the upper scree. Route-finding above 2,000 metres in cloud requires a map and compass or GPS. The staffed Belagua refuge provides dormitory accommodation and meals from June to September; advance booking is essential in July and August.

Highlights
- Summit of Navarre's highest peak at 2,444m — the historic convergence point of three medieval kingdoms marked by a stone border marker
- 360-degree panoramas across the Navarro-Aragonese Pyrenees extending into France and toward the Atlantic on clear days
- Pristine subalpine meadow approach through the Roncal Valley's high-mountain landscape
- Staffed Refugio de Belagua at the trailhead offering dormitory accommodation and meals for those making an early start
- Stone mojón at the summit commemorating the medieval boundary of Navarre, Aragon, and France
Tips for visiting
- Begin the ascent by 7am at the latest — afternoon thunderstorms develop rapidly over Pyrenean summits from June onward
- Wear a helmet above 2,000m — rockfall from natural causes and from other parties on the upper scree is a real hazard
- Book the Belagua refuge well in advance for July and August stays; contact the refugio directly for reservations
- Carry a printed 1:25,000 topographic map (Isaba–Roncal sheet) as cloud above the vegetation line can quickly disorient navigation
- Attempt the summit only in settled forecast conditions — the exposed Pyrenean top collects rapid weather changes and the scree descent in cloud is hazardous
When to visit
Mid-June to late September for the snow-free summit window. Clear morning weather is essential — a pre-dawn start from Belagua allows descent before the afternoon thunderstorms that typically build over the Pyrenean summits from early afternoon onward.
Accessibility
Mesa de los Tres Reyes is entirely inaccessible to wheelchair users, stroller users, and those with limited mobility. The route crosses high-altitude scree, involves scrambling sections, and demands sustained alpine effort across 18 kilometres. No adapted infrastructure exists above the Belagua refuge car park.
Frequently asked questions
Is Mesa de los Tres Reyes technically difficult to climb?
The standard route is a demanding alpine hike rather than a technical climb — no roping required, but the upper section crosses scree and requires short Class 2 scrambling. Mountaineering boots, trekking poles, map, and experience in mountain terrain are essential.
When is the route safe and snow-free?
The standard route is typically hikeable from mid-June to late September. Outside these dates, snow and ice on the upper sections require crampons and ice axe. The Belagua refuge staff can advise on current conditions.
Is the Refugio de Belagua staffed?
Yes, from June to September the refuge is staffed and offers dormitory accommodation and meals. Advance booking is essential in July and August. Outside the staffed season it may be accessible only as an emergency bivouac.
Can I drive to the Belagua trailhead?
Yes. The Refugio de Belagua is reached by a paved but narrow mountain road from Isaba in the Roncal Valley, suitable for standard vehicles in summer. The drive from Pamplona is approximately 125 km via the A-21 and NA-137.
