Meet your guide and embark on your transfer to the Marangu gate, which takes about 45 minutes. Once you reach the park gate, all hikers are required to register at the Park office. After registering at the Marangu gate, we drive to the Kilema gate. Upon arrival you will ensure that you have all your daypack items (containing at least drinking water, your lunch pack and extra clothing) and do a final check on your mountain bike. You will then start the first route section of 16km, (with your guide also on a mountain bike) from the Kilema gate (1 950m) to the Horombo hut (3 705m). Bikers with good fitness levels, mountain biking skills and subject to road conditions, will be able to cycle all the way to Horombo hut. Remember that the biggest cause of altitude sickness is ascending too high too quickly. We will be stopping regularly and to give your body the maximum time to adjust to the higher altitudes. We will reach Horombo around 15:00pm.
