A lovely small clearing with a few picnic tables and the Yellow Water river running beside it. The small car park is a good place to leave the car for one of the many walks in this area.

A really fun descent down into the forest. Be sure to watch where you put your feet as there are some deep holes on the way down.

Nice and peaceful place with a bench that's perfect for resting weary legs and watching the wildlife around the lake. Even with the new gravel path this area can get quite boggy so best to wear the boots.

You can come at this from a few different directions but any way, it's a nice point to take a break and enjoy the sound of the water flowing below

Yes, there is one easy dog-friendly route available. While the guide doesn't list a specific easy route by name, the area offers gentle walks like the Spelga Dam Shore Walk mentioned in regional research, which provides tranquil views along the reservoir's edges. For a slightly more challenging but still moderate option, consider the Yellow Water Picnic Area – Yellow Water River loop, which is 7.5 km long.
The terrain around Spelga Reservoir is varied, featuring rolling hills, rugged mountain outcrops, open moorland, bog, and pasture. You'll find paths that traverse sections of the historic Mourne Wall and offer panoramic views of the surrounding peaks. Be prepared for potentially wet and uneven surfaces, especially in moorland areas.
Yes, many of the dog-friendly routes are circular, allowing you to start and end at the same point. For example, the Yellow Water River – Pierce's Castle loop from Altaggart Mountain is a moderate 11.7 km circular hike, and the Yellow Water River – Red Bog Pond loop from Altaggart Mountain offers a more challenging 17.3 km circular option.
Spring and autumn generally offer the most pleasant conditions for hiking with dogs, with cooler temperatures and beautiful scenery. Summer can be lovely, but be mindful of warmer weather and ensure your dog has access to water. Winter hikes are possible but require appropriate gear for both you and your dog due to potentially cold, wet, or icy conditions on the exposed mountain trails.
Absolutely. For those seeking a more demanding adventure, the Yellow Water River – Red Bog Pond loop from Altaggart Mountain is classified as difficult, covering 17.3 km with over 550 meters of elevation gain. This route will test your endurance and reward you with spectacular views.
The trails offer stunning views of the Spelga Reservoir itself, with its tranquil waters. You'll also encounter the dramatic landscapes of the Mourne Mountains, including peaks like Hen Mountain and Slieve Doan. Sections of the historic Mourne Wall are incorporated into many routes, providing a unique cultural landmark. Keep an eye out for the curious "Magic Hill" or "Gravity Hill" near Spelga Dam, an optical illusion where cars appear to roll uphill.
Always bring plenty of water for both yourself and your dog, especially on longer routes. Essential items include a leash, waste bags, a portable water bowl, and appropriate clothing and footwear for the varied mountain weather. Consider a first-aid kit for both humans and dogs, and ensure your dog is microchipped and wearing an ID tag.
Yes, parking is generally available at common starting points for trails around Spelga Reservoir, such as near Spelga Dam Car Park or other access points to the Mourne Mountains. It's always advisable to check specific route details for parking information before you set out.
The area is highly rated by the komoot community, with an average score of 4.5 stars. Reviewers often praise the stunning panoramic views of the Mourne Mountains, the sense of wilderness, and the diverse terrain that makes for an engaging experience for both hikers and their dogs. The quiet, open moorland and the challenge of the mountain ascents are frequently highlighted.
While popular, the vastness of the Mourne Mountains means you can often find quieter spots. Routes that venture further into the open moorland, such as the Red Bog Pond – Yellow Water River loop from Crotlieve Mountain (10.7 km), might offer a more secluded experience compared to trails closer to the main reservoir access points. Early mornings or weekdays are also good times to avoid crowds.
